South Vietnam, officially the Republic of Vietnam (RVN; Vietnamese: Việt Nam Cộng hòa; VNCH, French: République du Viêt Nam), was a country in Southeast Asia from 1955 to 1975, with first international recognition in 1949 as the State of Vietnam. Its capital was located in Saigon, a city in Southern Vietnam. It was a member of the anti-communist and capitalist Western Bloc during the Cold War, especially after the division of Vietnam on 21 July 1954. South Vietnam was bordered by North Vietnam (Democratic Republic of Vietnam) to the north, Laos to the northwest, Cambodia to the southwest, and Thailand across the Gulf of Thailand to the southwest. In 1975, it was succeeded by the Republic of South Vietnam, which was de facto controlled by the communist North. On 2 July 1976, the Republic of South Vietnam and North Vietnam merged to form the Socialist Republic of Vietnam.

At the end of the Second World War, the communist Việt Minh of Hồ Chí Minh, led the August Revolution of different political organizations against the Nguyễn dynasty and its Japanese puppet state on 16 August 1945. On 19 August, the Việt Minh took control of Hanoi. On August 25, the Nguyễn dynasty collapsed. In Hanoi (Northern Vietnam), the Việt Minh proclaimed the establishment of the Democratic Republic of Vietnam to replace the old regime on 2 September 1945. The Viet Minh did not publicize it as a communist organization but as a neutral and nationalist one to attract or cooperate with non-communists and receive support from the people,, however the communists sought to suppress politicians and political organizations who did not submit to them with the goal of establishing a future communist state for Vietnam. The French returned to French Indochina (including Vietnam) to re-establish their colonial rule here on 23 September 1945 with a legal recognition of the victorious Allies that they were a member. Although the Viet Minh tried to make peace with France and France recognized the Việt Minh's state as a "Free State" within the French Union with an agreement on 6 March 1946, French army later still clashed with the Việt Minh on December 19, leading to the First Indochina War. During the war on 8 March 1949, under a pressure of the domestic left, France agreed that they would give a non-communist Vietnam independence and unification. After two preliminary treaties with Vietnamese anti-communists and a transition process, the French formed the State of Vietnam, a rival state of anti-communist Vietnamese politicians in Saigon, led by former Nguyễn emperor Bảo Đại. With this event, the French abolished the old-style colonial regime in Vietnam, France recognized the independence and unification of the State of Vietnam within the French Union, but this state still depended on France as an associated state like other two countries within Indochina. However, the autonomy of the State of Vietnam within the French Union was still higher than that of Malaysia within the British Commonwealth from 1948 to 1957. The state was proclaimed on 2 July 1949. The formation of the State of Vietnam on 8 March 1949 made this French colonial war part of the Cold War between the United States and the Soviet Union, culminating in the American recognition of Saigon regime in February 1950 and subsequent aid to the French in the war against the communist Việt Minh. The First Indochina War of France itself was also similar to the Malayan Emergency (1948-1960) of the British. The French government agreed to give the State of Vietnam complete independence with the Matignon Accords on 4 June 1954, however they were never completed. After the Việt Minh with the main aid of China defeated the French Union with an armistice and an accompanying declaration in the Geneva Conference on 21 July 1954 (taking effect July 22), the State of Vietnam was forced to abandon its claims to the North while the Việt Minh's state was recognized by the French and took power in the North. With the American support, a 1955 referendum on the state's future form of government was widely marred by electoral fraud and resulted in the deposal of Bảo Đại by Prime Minister Ngô Đình Diệm, who proclaimed himself president of the new republic on 26 October 1955. South Vietnam also withdrew from the French Union on 9 December 1955. South Vietnam then held parliamentary elections and subsequently promulgated a constitution on 26 October 1956. After a 1963 coup, Diệm was killed and his dictatorship was overthrown in a CIA-backed military rebellion on November 2, and a series of short-lived military governments followed. General Nguyễn Văn Thiệu then led the country after a US-encouraged civilian presidential election from 1967 until 1975.

The Vietnam War, a Cold War conflict between North and South Vietnam, started on 1 November 1955 and escalated in March 1959 when North Vietnam accepted the use of force in the South. North Vietnam de facto established the National Liberation Front for South Vietnam (Việt Cộng) the next year. North Vietnam was supported mainly from China and the Soviet Union. Larger escalation of the insurgency occurred in 1965 with foreign intervention to help South Vietnam (mostly the U.S.) and the introduction of regular forces of Marines, followed by Army units to supplement the cadre of military advisors guiding the Southern armed forces. North Vietnam was also helped by foreign armies, mostly Chinese. A regular bombing campaign over North Vietnam was conducted by offshore US Navy airplanes, warships, and aircraft carriers joined by the South Vietnamese and American Air Force squadrons from 1965 to 1968. Fighting peaked up to that point during the Tet Offensive of February 1968, when there were over a million South Vietnamese soldiers and 500,000 US soldiers in South Vietnam. In 1969, the North Vietnam-controlled Việt Cộng established the Provisional Revolutionary Government of the Republic of South Vietnam (PRG) to challenge the legitimacy of the South Vietnamese government. What started as a guerrilla war eventually turned into a more conventional fight as the balance of power became equalized. An even larger, armored invasion from the North commenced during the 1972 Easter Offensive following US ground-forces withdrawal. Under the support of the US air force, the South Vietnamese army successfully stopped the communist attack. In the Second Battle of Quảng Trị, the South Vietnamese army successfully recaptured part of Quang Tri territory from the enemy. However, the Saigon government still lost about 10% of its territory to the communists.

Despite a truce agreement under the Paris Peace Accords, concluded in January 1973 after five years of on-and-off negotiations, fighting continued almost immediately afterwards. The regular North Vietnamese army and Viet Cong auxiliaries launched a major second combined-arms conventional invasion in 1975. Communist forces overran Saigon and South Vietnamese president unconditionally surrendered to North Vietnamese army on the radio on 30 April 1975, marking the end of anti-communist regime in South Vietnam. In 1976, the North Vietnam-controlled Republic of South Vietnam (PRG) and North Vietnam merged to form the Socialist Republic of Vietnam.

Etymology

Main article: Names of Vietnam

The official name of the South Vietnamese state was the "Republic of Vietnam" (Vietnamese: Việt Nam Cộng hòa; French: République du Viêt Nam). The North was known as the "Democratic Republic of Vietnam".

Việt Nam (Vietnamese pronunciation: [vjə̀tnam]) was the name adopted by Emperor Gia Long in 1804. It is a variation of "Nam Việt" (南 越, Southern Việt), a name used in ancient times. In 1839, Emperor Minh Mạng renamed the country Đại Nam ("Great South"). In 1945, the nation's official name was changed back to "Vietnam" by the government of Bảo Đại. The name is also sometimes rendered as "Viet Nam" in English. The term "South Vietnam" became common usage in 1954, when the Geneva Conference provisionally partitioned Vietnam into communist and capitalist parts.

Other names of this state were commonly used during its existence such as "Free Vietnam", "Free South", "National Government", "National side", and the "Government of Vietnam".

Before World War II, the southern part of Vietnam had been administered as a complete colony of France since 1862 (Nam Kỳ). It had been annexed by France and even elected a deputy to the French National Assembly. It was more "evolved", and French interests were stronger than in other parts of Indochina, notably in the form of French-owned rubber plantations. The northern part of Vietnam or Tonkin (Bắc Kỳ) was under a French resident general (thống sứ). Between Tonkin in the north and Cochinchina in the south was Annam (Trung Kỳ), under a French resident superior (khâm sứ). The Nguyễn dynasty emperors of Vietnam, residing in Huế, since 1883 had been the nominal rulers of Annam and Tonkin protectorates, which had parallel French and Vietnamese systems of administration, but French political power in Tonkin was stronger than in Annam. A French governor-general (toàn quyền) administered all the five parts of French Indochina (Tonkin, Annam, Cochinchina, Laos, and Cambodia) while Cochinchina (Nam Kỳ) was under a French governor (thống đốc). During World War II, French Indochina was administered by Vichy France and occupied by Japan in September 1940. The communist Việt Minh was formed as one of nationalist groups of Vietnam in 1941. After Japanese troops overthrew the Vichy administration on 9 March 1945, Nguyễn Emperor Bảo Đại proclaimed his Vietnam independent and to regain Cochinchina to establish the Empire of Vietnam on 11 March 1945. However, it was a puppet state of Japan within the Greater East Asia Co-Prosperity Sphere. After the Japanese emperor claimed to surrender to the Allies on the radio on August 15, with the August Revolution led by communists, Emperor Bảo Đại abdicated on 25 August 1945 and Việt Minh leader Hồ Chí Minh proclaimed the Democratic Republic of Vietnam (DRV) in Hanoi on September 2. Since its establishment, the Viet Minh had never publicized it as a communist organization but as a neutral and nationalist one to attract or cooperate with non-communists and receive support from the people, however the communists sought to suppress politicians and political organizations who did not submit to them with the goal of establishing a future communist state for Vietnam. The Viet Minh tried to make peace with France and France recognized the Việt Minh's state as a "Free State" within the French Union with an agreement on 6 March 1946. In June 1946, France declared Cochinchina a republic, separate from the northern and central parts. A Chinese Kuomintang army arrived to occupy Vietnam's north of the 16th parallel north, while a British-led force occupied the south in September. The British-led force facilitated the return of French forces who fought the Viet Minh for control of the south. The French Indochina War began on 19 December 1946, the French defeated the Việt Minh in Hanoi on 18 February 1947. France returned to Vietnam but no longer recognized this place as a colony but a territory having a higher status. With co-operation between indigenous anti-communists and France, two preliminary treaties at Ha Long Bay recognizing Vietnam's independence and unity were signed between ex-emperor Bao Dai (representative of the anti-communist faction) and France on 7 December 1947 and 5 June 1948, and the Provisional Central Government of Vietnam was established on 27 May 1948 as a transitional government partly replacing the French protectorates of Tonkin (Northern Vietnam) and Annam (Central Vietnam), until French Cochinchina (Southern Vietnam) could be reunited with the rest of the country under a unified French-associated administration.

The State of Vietnam was created as a unified and associated state within the French Union by the Élysée Accords on 8 March 1949. Former emperor Bảo Đại accepted the position of chief of state (quốc trưởng). In its Domain of the Crown, he was still officially titled as the "Emperor of the Nguyễn dynasty". This was known as the "Bảo Đại Solution". The colonial struggle in Vietnam became part of the global Cold War. This state was proclaimed on July 2. In 1950, China, the Soviet Union and other communist nations recognised the DRV while the United States and other non-communist states recognised the Bảo Đại government. In 1953, Bảo Đại responded to the communist Việt Minh program of land redistribution and rent reduction with a decree declaring that rents for land should not exceed 15 percent of the crop. The decree was unenforceable and rendered null by a failing colonial government and, in any case, contained loopholes that could have been exploited by landlords. In 1954, the French government of Prime Minister Joseph Laniel was forced to sign the Matignon Accords with the State of Vietnam government of Prime Minister Nguyễn Phúc Bửu Lộc to recognize the complete independence of Vietnam within the French Union on 4 June 1954. However, the Accords had not yet been ratified by the heads of both countries.

About 1 million North Vietnamese refugees left the newly created communist North Vietnam during Operation Passage to Freedom (1954-1955). Hải Phòng, October 1954.

On 21 July 1954, the war ended, France and the Việt Minh (DRV) agreed at the Geneva Conference with an armistice effective at 24:00 on July 22 accompanied by a declaration that the Viet Minh army withdrew all to the North and the French Union army withdrew all to the South, and Vietnam would be temporarily divided at 17th parallel north and State of Vietnam would rule the territory south of the 17th parallel, pending unification on the basis of supervised elections in 1956. France also re-recognised independence of Vietnam. At the time of the conference, it was expected that the South would continue to be a French dependency. However, South Vietnamese Premier Ngô Đình Diệm, who preferred American sponsorship to French, rejected the agreement. When Vietnam was divided, 800,000 to 1 million North Vietnamese, mainly (but not exclusively) Roman Catholics, sailed south as part of Operation Passage to Freedom due to a fear of religious persecution in the North. About 90,000 Việt Minh were evacuated to the North while 5,000 to 10,000 cadre remained in the South, most of them with orders to refocus on political activity and agitation. The Saigon-Cholon Peace Committee, the first communist front, was founded in 1954 to provide leadership for this group.

About the communist Việt Minh, on 7 March 1951, it and the communist National United League of Vietnam (Hội Liên Việt) merged to form the communist Vietnamese United Front (Mặt trận Liên Việt). Nonetheless, people continued to call the new front as the Việt Minh. Later, after communists took power in North Vietnam, the United Front (Việt Minh) changed into the current communist Vietnam Fatherland Front (Mặt trận Tổ quốc Việt Nam) on 10 September 1955.

Republic of Ngô Đình Diệm: 1955–1963

South Vietnamese President Ngô Đình Diệm meeting with Indian Prime Minister Jawaharlal Nehru during a state visit to India on 8 November 1957. India was a neutral country during the Cold War and adopted a socialist economic system.

In July 1955, Diệm announced in a broadcast that South Vietnam would not participate in the elections specified in the Geneva Accords. As Saigon's delegation did not sign the Geneva Accords, it was not bound by it, despite having been part of the French Union, which was itself bound by the Accords because the Matignon Accords that made Saigon gain independence from France never took effect legally. He also claimed the communist government in the North created conditions that made a fair election impossible in that region. Dennis J. Duncanson described the circumstances prevailing in 1955 and 1956 as "anarchy among sects and of the retiring Việt Minh in the South, the 1956 campaign of terror from Hanoi's land reform and resultant peasant uprising around Vinh in the North".

Diệm held a referendum on 23 October 1955 to determine the future of the country. He asked voters to approve a republic, thus removing Bảo Đại as head of state. The poll was supervised by his younger brother, Ngô Đình Nhu. Diệm was credited with 98 percent of the votes. In many districts, there were more votes to remove Bảo Đại than there were registered voters (e.g., in Saigon, 133% of the registered population reportedly voted to remove Bảo Đại). His American advisors had recommended a more modest winning margin of "60 to 70 percent". Diệm, however, viewed the election as a test of authority. On 26 October 1955, Diệm declared himself the president of the newly proclaimed Republic of Vietnam. South Vietnam withdrew from the French Union on 9 December 1955. The French, who needed troops to fight in Algeria (then French internal part) and were increasingly sidelined by the United States, completely withdrew from Vietnam by April 1956.

Under Bảo Đại, Saigon planned to organize parliamentary elections and promulgate a constitution to establish a republic, but not in time due to the progress of the war. However, South Vietnam under Diệm held parliamentary elections and subsequently promulgated a constitution on 26 October 1956.

The Geneva Accords promised elections in 1956 to determine a national government for a united Vietnam. In 1957, independent observers from India, Poland, and Canada representing the International Control Commission (ICC) stated that fair, unbiased elections were not possible, reporting that neither South nor North Vietnam had honored the armistice agreement: "The elections were not held. South Vietnam, which had not signed the Geneva Accords, did not believe the Communists in North Vietnam would allow a fair election. In January 1957, the ICC agreed with this perception, reporting that neither South nor North Vietnam had honored the armistice agreement. With the French gone, a return to the traditional power struggle between north and south had begun again."

In October 1956 Diệm, with US prodding, launched a land reform program restricting rice farm sizes to a maximum of 247 acres per landowner with the excess land to be sold to landless peasants. More than 1.8m acres of farm land would become available for purchase, the US would pay the landowners and receive payment from the purchasers over a six-year period. Land reform was regarded by the US as a crucial step to build support for the nascent South Vietnamese government and undermine communist propaganda.

The North Vietnamese Communist Party approved a "people's war" on the South at a session in January 1959 and this decision was confirmed by the Politburo in March. In May 1959, Group 559 was established to maintain and upgrade the Ho Chi Minh Trail, at this time a six-month mountain trek through Laos. About 500 of the "regroupees" of 1954 were sent south on the trail during its first year of operation. Regarding the relations with communist North Vietnam, Diệm maintained total hostility and never made a serious effort to establish any relations with it.

Diệm attempted to stabilise South Vietnam by defending against Việt Cộng activities. He launched an anti-communist denunciation campaign (Tố Cộng) against the Việt Cộng and military campaigns against three powerful group – the Cao Đài, Hòa Hảo and the Bình Xuyên organised crime syndicate whose military strength combined amounted to approximately 350,000 fighters (see also: Battle of Saigon (1955)).

By 1960 the land reform process had stalled. Diệm had never truly supported reform because many of his biggest supporters were the country's largest landowners. While the US threatened to cut aid unless land reform and other changes were made, Diệm correctly assessed that the US was bluffing.

Like Bảo Đại, the Saigon regime under Ngô Đình Diệm was a dictatorship but not a liberal democracy; although Diệm overthrew Bảo Đại to establish a nominal republic and he was an ally of the US. Based on mass-organizations and secret networks as effective instruments, the Cần Lao Party with the Person Dignity Theory played a considerable role in creating a political groundwork for the power of Diệm's family and helped them to control all political activities in South Vietnam.

Opening of the Bien-hoa Highway in South Vietnam by President Ngo Dinh Diem, 28 April 1961

Throughout this period, the level of US aid and political support increased. In spite of this, a 1961 US intelligence estimate reported that "one-half of the entire rural region south and southwest of Saigon, as well as some areas to the north, are under considerable Communist control. Some of these areas are in effect denied to all government authority not immediately backed by substantial armed force. The Việt Cộng's strength encircles Saigon and has recently begun to move closer in the city." The report, later excerpted in The Pentagon Papers, continued:

Many feel that [Diem] is unable to rally the people in the fight against the Communists because of his reliance on virtual one-man rule, his tolerance of corruption extending even to his immediate entourage, and his refusal to relax a rigid system of public controls.

Support for the North Vietnam-controlled Viet Cong (NLF/VC) was driven by resentment of Diem's reversal of Viet Minh land reforms in the countryside. The Viet Minh had confiscated large private landholdings, reduced rents and debts, and leased communal lands, mostly to poorer peasants. Diem brought the landlords back, people who had been farming land for years had to return it to landlords and pay years of back rent. Marilyn B. Young wrote that "The divisions within villages reproduced those that had existed against the French: 75% support for the NLF, 20% trying to remain neutral and only 5% firmly pro-Saigon government".

The Diệm government lost support among the populace, and from the Kennedy administration, due to its repression of Buddhists and military defeats by the Việt Cộng. Notably, the Huế Phật Đản shootings of 8 May 1963 led to the Buddhist crisis, provoking widespread protests and civil resistance. The situation came to a head when the Special Forces were sent to raid Buddhist temples across the country, leaving a death toll estimated to be in the hundreds. However, the people who support Diem's regime claim he sponsored and supported many Buddhist organizations, and Buddhism flourished under his regime. Before Diệm was overthrown, on 3 September 1963, South Vietnamese army (ARVN) also defeated communists in a small battle at Go Cong. Diệm feared the escalation of American military personnel in South Vietnam, which threatened his nationalist credentials and the independence of his government. In 1963, Diệm's government secretly discussed with North Vietnam on the issue of peace and reunification between the two sides and reached an important consensus with the communists.

Diệm's removal and assassination set off a period of political instability and declining legitimacy of the Saigon government. Saigon's ability to fight communism as well as build and govern the country was seriously weakened after the fall of his dictatorship. General Dương Văn Minh became president, but he was ousted in January 1964 by General Nguyễn Khánh. Phan Khắc Sửu was named head of state, but power remained with a junta of generals led by Khánh, which soon fell to infighting. Meanwhile, the Gulf of Tonkin incident of 2 August 1964 led to a dramatic increase in direct US-allied participation in the war in South Vietnam, with nearly 200,000 American troops deployed by the end of the year. North Vietnam was also helped by foreign armies, mostly Chinese. Khánh sought to capitalize on the crisis with the Vũng Tàu Charter, a new constitution that would have curtailed civil liberties and concentrated his power, but was forced to back down in the face of widespread protests and strikes. Coup attempts followed in September and February 1965, the latter resulting in Air Marshal Nguyễn Cao Kỳ becoming prime minister and General Nguyễn Văn Thiệu becoming nominal head of state. A regular bombing campaign over North Vietnam was conducted by offshore US Navy airplanes, warships, and aircraft carriers joined by the South Vietnamese and American Air Force squadrons from 1965 to 1968.

Kỳ and Thiệu functioned in those roles until 1967, bringing much-desired stability to the government. They imposed censorship and suspended civil liberties, and intensified anticommunist efforts. Under pressure from the US, they held elections for president and the legislature in 1967. The Senate election took place on 2 September 1967. The Presidential election took place on 3 September 1967, Thiệu was elected president with 34% of the vote in a widely criticised poll. Like Diệm, Thiệu was among the hardline anti-communists and did not accept a political alliance with the South Vietnamese communists (de facto controlled by the North); however, despite the South Vietnamese constitution considering Vietnam a unified country, he advocated a two-state solution with North Vietnam to join the United Nations together and co-exist peacefully to wait for the day of democratic unification. The Parliamentary election took place on 22 October 1967.

On 31 January 1968, the People's Army of Vietnam (PAVN) of North Vietnam and its Việt Cộng broke the traditional truce accompanying the Tết (Lunar New Year) holiday. The Tet Offensive failed to spark a national uprising and was militarily disastrous. By bringing the war to South Vietnam's cities, however, and by demonstrating the continued strength of communist forces, it marked a turning point in US support for the government in South Vietnam. The new administration of Richard Nixon introduced a policy of Vietnamization to reduce US combat involvement and began negotiations with the North Vietnamese to end the war. Thiệu used the aftermath of the Tet Offensive to sideline Kỳ, his chief rival.

The Land to the Tiller project carried out in South Vietnam from 1970 to 1973 was based on a proposal by Roy Prosterman, a prominent American "land-rights activist", who the US government of the time recruited within its efforts against communists. Drawing on experiences in other countries (particularly in Latin America), Prosterman proposed a "land-to-the-tiller" program to compete with the communists for the allegiance of the peasants. The plan mimicked the communists' land expropriation strategy, coupled with monetary compensation to the former landowners. On 26 March 1970, with the war still underway, the government of South Vietnam began implementation of the Land-to-the-Tiller program following Prosterman's model. In total, the United States financed 339 million US dollars of the reform's 441 million dollars of expenses. Individual holdings were limited to 15 hectares. Legal titles were extended to peasants in areas under control of the Republic of Vietnam government to whom land had previously been distributed by the communists.

In accordance with the Paris Peace Accords signed on 27 January 1973 (taking effect January 28), US military forces withdrew from South Vietnam at the end of March 1973 while PAVN forces in the South were permitted to remain in place.

North Vietnamese leaders had expected that the ceasefire terms would favour their side. As Saigon began to roll back the Việt Cộng, they found it necessary to adopt a new strategy, hammered out at a series of meetings in Hanoi in March 1973, according to the memoirs of Trần Văn Trà. As the Việt Cộng's top commander, Trà participated in several of these meetings. A plan to improve logistics was prepared so that the PAVN would be able to launch a massive invasion of the South, projected for 1976. A gas pipeline would be built from North Vietnam to the Việt Cộng provisional capital in Lộc Ninh, about 60 mi (97 km) north of Saigon.

On 15 March 1973, US President Richard Nixon implied that the US would intervene militarily if the communist side violated the ceasefire. Public reaction was unfavorable, and on 4 June 1973 the US Senate passed the Case–Church Amendment to prohibit such intervention. The oil price shock of October 1973 caused significant damage to the South Vietnamese economy. A spokesman for Thiệu admitted in a TV interview that the government was being "overwhelmed" by the inflation caused by the oil shock, while an American businessman living in Saigon stated after the oil shock that attempting to make money in South Vietnam was "like making love to a corpse". One consequence of the inflation was the South Vietnamese government had increasing difficulty in paying its soldiers and imposed restrictions on fuel and munition usage.

After two clashes that left 55 South Vietnamese soldiers dead, President Thiệu announced on 4 January 1974 that the war had restarted and that the Paris Peace Accord was no longer in effect. There were over 25,000 South Vietnamese casualties during the ceasefire period. The same month, China attacked South Vietnamese forces in the Paracel Islands on the South China Sea, taking control of the islands. Saigon later objected diplomatically. North Vietnam recognized Chinese territorial claims in the South China Sea because China was one of two main allies in the Vietnam War. The "Operation Tran Hung Dao 48" was a campaign conducted by the South Vietnamese Navy in February 1974 to station troops on unoccupied islands to assert Vietnam's sovereignty over the Spratly archipelago after the Battle of the Paracel Islands. After communist reunification in 1976, Hanoi has carefully praised the South Vietnamese forces that took part in the battle, while trying to avoid praising the Saigon regime as always to keep the image of the current regime. After the battle, the US refused Saigon's requests for assistance because the US signed the Paris Peace Accords and the US and South Vietnam had no mutual defense treaty.

In August 1974, Nixon was forced to resign as a result of the Watergate scandal, and the US Congress voted to reduce assistance to South Vietnam from $1 billion a year to $700 million. By this time, the Ho Chi Minh trail, once an arduous mountain trek, had been upgraded into a drivable highway with gasoline stations. On 10 December 1974, South Vietnam did recapture a series of hills from communist North Vietnam in the Battle of Phú Lộc, but this was the army's last victory before suffering repeated defeats and collapse.

President Nguyễn Văn Thiệu used samples of South Vietnamese off-shore oil to light a flame commemorating his country's war dead at the military cemetry in Thu Duc, 1 February 1975.

On 12 December 1974, the PAVN launched an invasion at Phuoc Long as the beginning of the 1975 spring offensive to test the South Vietnamese combat strength and political will and whether the US would respond militarily. With no US military assistance forthcoming, the ARVN were unable to hold and the PAVN successfully captured many of the districts around the provincial capital of Phuoc Long, weakening ARVN resistance in stronghold areas. President Thiệu later abandoned Phuoc Long in early January 1975. As a result, Phuoc Long was the first provincial capital to fall to the PAVN.

In 1975, the PAVN launched an offensive at Ban Me Thuot in the Central Highlands. The South Vietnamese unsuccessfully attempted a defence and counterattack but had few reserve forces, as well as a shortage of spare parts and ammunition. As a consequence, Thiệu ordered a withdrawal of key army units from the Central Highlands, which exacerbated an already perilous military situation and undermined the confidence of the ARVN soldiers in their leadership. The retreat became a rout exacerbated by poor planning and conflicting orders from Thiệu. PAVN forces also attacked south and from sanctuaries in Laos and Cambodia capturing Huế and Da Nang and advanced southwards. As the military situation deteriorated, ARVN troops began deserting. By early April, the PAVN had overrun almost 3/5th of the South.

Thiệu requested aid from US President Gerald Ford, but the US Senate would not release extra money to provide aid to South Vietnam, and had already passed laws to prevent further involvement in Vietnam. In desperation, Thiệu recalled Kỳ from retirement as a military commander, but resisted calls to name his old rival prime minister.

Fall of Saigon: 30 April 1975

The president of the Republic of Vietnam (South Vietnam) Trần Văn Hương nominated Nguyễn Văn Thiệu and Trần Thiện Khiêm as his envoys to visit the Republic of China (Taiwan) and other countries, 25 April 1975

With Operation Babylift from 3 April to 26 April 1945; over 3,300 South Vietnamese infants and children had been airlifted by the United States and other Western countries (including Australia, France, West Germany, and Canada), although the actual number has been variously reported. Morale was low in South Vietnam as the PAVN advanced. A last-ditch defense was made mostly by the ARVN 18th Division led by Brigadier General Lê Minh Đảo at the Battle of Xuân Lộc from 9–21 April. The North Vietnamese communists demanded that Thieu resign so peace negotiations could take place; under pressure from within the country, Thiệu was forced to resign on 21 April 1975, and fled to Taiwan under the name of an envoy of the South Vietnamese president. He nominated his Vice President Trần Văn Hương as his successor. After only one week in office, the South Vietnamese national assembly voted to hand over the presidency to General Dương Văn Minh. Minh was seen as a more conciliatory figure toward the North, and it was hoped he might be able to negotiate a more favourable settlement to end the war. After that, on 28 April 1975, South Vietnamese president Minh immediately asked the US defense attaché to leave South Vietnam to create conditions for negotiations with Hanoi. The communist North, however, was not interested in negotiations to create a coalition government in the South with anti-communists and neutrals, and its forces captured Saigon. Minh unconditionally surrendered to North Vietnam on the radio on 30 April 1975.

During the hours leading up to the surrender, the United States undertook a massive evacuation of US government personnel as well as high-ranking members of the ARVN and other South Vietnamese who were seen as potential targets for persecution by the Communists. Many of the evacuees were taken directly by helicopter to multiple aircraft carriers waiting off the coast.

Communist rule and reunification, 1975-1976

Main articles: Provisional Revolutionary Government of the Republic of South Vietnam, Flag of South Vietnam, and Vietnamese democracy movement

Following the surrender of Saigon to North Vietnamese forces on 30 April 1975; South Vietnam was de facto overthrown, while the communists took power throughout Vietnam and there was no place for neutrals and anti-communists. The Provisional Revolutionary Government of the Republic of South Vietnam (PRG) of the Việt Cộng (de facto controlled by the North) officially became the government of South Vietnam, which merged with North Vietnam to create the communist Socialist Republic of Vietnam on 2 July 1976. The North's flag, national anthem, capital, and constitution were still chosen. After reunification, Hanoi abandoned the policy of neutrality in its relations with the Soviet Union and China to choose to be pro-Soviet. The North Vietnam-controlled Việt Cộng was merged with the Vietnamese Fatherland Front of the North on 4 February 1977. Now the yellow flag of the old regime is being banned by the communist regime in Vietnam but is still being used in anti-communist Vietnamese overseas communities (however, not all Vietnamese dissidents use this flag) and is recognized by many places in Australia, the US, and Canada.

South Vietnam went through many political changes during its short life. Initially, former Emperor Bảo Đại served as Head of State of the State of Vietnam and Emperor of its Domain of the Crown. He was unpopular however, largely because monarchical leaders were considered collaborators during French rule and because he had spent his reign absent in France.

In 1955, Prime Minister Ngô Đình Diệm held a referendum to decide whether the State of Vietnam would remain a monarchy or become a republic. This referendum was blatantly rigged in favor of a republic. Not only did an implausible 98% vote in favor of deposing Bảo Đại, but over 380,000 more votes were cast than the total number of registered voters; in Saigon, for instance, Diệm was credited with 133% of the vote. Diệm proclaimed himself the president of the newly formed Republic of Vietnam. Despite successes in politics, economics and social change in the first 5 years, Diệm quickly became a dictatorial leader. With the support of the United States government and the CIA, ARVN officers led by General Dương Văn Minh staged a coup and killed him in 1963. The military held a brief interim military government until General Nguyễn Khánh deposed Minh in a January 1964 coup. Until late 1965, multiple coups and changes of government occurred, with some civilians being allowed to give a semblance of civil rule overseen by a military junta.

In 1965, the feuding civilian government voluntarily resigned and handed power back to the nation's military, in the hope this would bring stability and unity to the nation. An elected constituent assembly including representatives of all the branches of the military decided to switch the nation's system of government to a semi-presidential system. Military rule initially failed to provide much stability however, as internal conflicts and political inexperience caused various factions of the army to launch coups and counter-coups against one another, making leadership very tumultuous. The situation within the ranks of the military stabilised in mid-1965 when the Republic of Vietnam Air Force chief Nguyễn Cao Kỳ became Prime Minister, with General Nguyễn Văn Thiệu as the figurehead chief of state. As Prime Minister, Kỳ consolidated control of the South Vietnamese government and ruled the country with an iron fist.

In June 1965, Kỳ's influence over the ruling military government was solidified when he forced civilian prime minister Phan Huy Quát from power. Often praising aspects of Western culture in public, Ky was supported by the United States and its allied nations, though doubts began to circulate among Western officials by 1966 on whether or not Ky could maintain stability in South Vietnam. A repressive leader, Ky was greatly despised by his fellow countrymen. In early 1966, protesters influenced by popular Buddhist monk Thích Trí Quang attempted an uprising in Quang's hometown of Da Nang. The uprising was unsuccessful and Ky's repressive stance towards the nation's Buddhist population continued.

In 1967, the unicameral National Assembly was replaced by a bicameral system consisting of a House of Representatives or lower house (Hạ Nghị Viện) and a Senate or upper House (Thượng Nghị Viện) and South Vietnam held its first elections under the new system. The military nominated Nguyễn Văn Thiệu as their candidate, and he was elected with a plurality of the popular vote. Thieu quickly consolidated power much to the dismay of those who hoped for an era of more political openness. He was re-elected unopposed in 1971, receiving a suspiciously high 94% of the vote on an 87% turn-out. Thieu ruled until the final days of the war, resigning on 21 April 1975. Vice-president Trần Văn Hương assumed power for a week, but on 27 April the Parliament and Senate voted to transfer power to Dương Văn Minh who was the nation's last president and who unconditionally surrendered to the Communist forces on 30 April 1975.

The National Assembly/House of Representatives was located in the Saigon Opera House, now the Municipal Theatre, Ho Chi Minh City, while the Senate was located at 45-47 Bến Chương Dương Street (đường Bến Chương Dương), District 1, originally the Chamber of Commerce, and now the Ho Chi Minh City Stock Exchange.

The South Vietnamese government was regularly accused of holding a large number of political prisoners, the exact number of which was a source of contention. Amnesty International, in a report in 1973, estimated the number of South Vietnam's civilian prisoners ranging from 35,257 (as confirmed by Saigon) to 200,000 or more. Among them, approximately 22,000–41,000 were accounted "communist" political prisoners.

  • Lê Văn Hoạch (1946–1947)
  • Nguyễn Văn Xuân (1947–1948)
• 1948–1949 Provisional Central Government of Vietnam (Chính phủ lâm thời Quốc gia Việt Nam). This "pre-Vietnam" government prepared for a unified Vietnamese state, but the country's full reunification was delayed for a year because of the problems posed by Cochinchina's legal status.
  • Nguyễn Văn Xuân (1948–1949)

Regions

See also: State of Vietnam § Autonomous regions

Throughout its history South Vietnam had many reforms enacted that affected the organisation of its administrative divisions.

The "Bảo Đại Palace" in Buôn Ma Thuột, one of the residences of the Head of State located in the Domain of the Crown.

The Domain of the Crown was officially established as an administrative unit of autonomous territories within the State of Vietnam on 15 April 1950. In the areas of the Domain of the Crown, the Chief of State Bảo Đại was still officially (and legally) titled as the "Emperor of the Nguyễn dynasty". It was established to preserve French interests in French Indochina and to limit Kinh (Vietnamese) immigration into predominantly minority areas, halting Vietnamese influence in these regions while preserving the influences of both French colonists and indigenous rulers. On 11 March 1955 Prime Minister Ngô Đình Diệm dissolved the Domain of the Crown reducing both the power of the Chief of State Bảo Đại and the French directly annexing these areas into the State of Vietnam as the crown regions still in South Vietnam would later become Cao nguyên Trung phần in the Republic of Vietnam.

Following the creation of the State of Vietnam and the establishment of its government, the Chief of State Bảo Đại signed the two ordinances related to the administration and local governance of the State of Vietnam, namely Ordinance No. 1 ("Organisation and Operation of civil authorities in Vietnam") and Ordinance No. 2 ("Statutes of Government office"). These ordinances renamed the regions to Bắc Việt (北越), Trung Việt (中越), and Nam Việt (南越). Later on 4 August 1954 the government of the State of Vietnam enacted Ordinance No. 21 which renamed the regions to Bắc Phần (北分), Trung Phần (中分), and Nam Nhần (南分). On 24 October 1956 the South Vietnamese president Ngô Đình Diệm officially abolished the three region system as the regions were divided into smaller regions in South Vietnam. At the time, President Ngô Đình Diệm enacted a reform of the administrative divisions system of the Republic of Vietnam in the form of Decree 147a/NV. This decree divided the region of Trung phần into Trung nguyên Trung phần (the Central Midlands) and Cao nguyên Trung phần (the Central Highlands).

The offices of appointed representative and assistant representative of the central government were created for the region of Trung phần, the main representative had an office in Buôn Ma Thuột, while the assistant had an office in Huế.

Following the 1963 United States-backed coup d'état that outsted Diệm, the Central Government's Representatives in the Trung phần region were gradually replaced by the control of the Tactical zone's Commanders (Tư lệnh Vùng Chiến thuật), which replaced a civil administration with a military one. However, following the 1967 Senate election the military administration was replaced back with civilian administrators.

On 1 January 1969, during the presidency of Nguyễn Văn Thiệu, Act 001/69 became effective which abolished the offices of government's representative and assistant government's representative, this was later followed on 12 May 1969 with Decree 544 – NĐ/ThT/QTCS which completely abolished the civil administration in Trung nguyên Trung phần in favour of the Tư lệnh Vùng Chiến thuật.

The Geneva Accords promised elections in 1956 to determine a national government for a united Vietnam. Neither the United States government nor Ngô Đình Diệm's State of Vietnam signed anything at the 1954 Geneva Conference. With respect to the question of reunification, the non-communist Vietnamese delegation objected strenuously to any division of Vietnam, but lost out when the French accepted the proposal of communist Viet Minh delegate Phạm Văn Đồng, who proposed that Vietnam eventually be united by elections under the supervision of "local commissions". The United States countered with what became known as the "American Plan", with the support of South Vietnam and the United Kingdom. It provided for unification elections under the supervision of the United Nations, but was rejected by the Soviet delegation and North Vietnamese. U.S. President Dwight D. Eisenhower wrote in 1954 that "I have never talked or corresponded with a person knowledgeable in Indochinese affairs who did not agree that had elections been held as of the time of the fighting, possibly eighty percent of the population would have voted for the Communist Ho Chi Minh as their leader rather than Chief of State Bảo Đại. Indeed, the lack of leadership and drive on the part of Bảo Đại was a factor in the feeling prevalent among Vietnamese that they had nothing to fight for." According to the Pentagon Papers, however, from 1954 to 1956 "Ngô Đình Diệm really did accomplish miracles" in South Vietnam: "It is almost certain that by 1956 the proportion which might have voted for Ho—in a free election against Diệm—would have been much smaller than eighty percent." In 1957, independent observers from India, Poland, and Canada representing the International Control Commission (ICC) stated that fair, unbiased elections were not possible, reporting that neither South nor North Vietnam had honored the armistice agreement.

The failure to unify the country in 1956 led in 1959 to the foundation of the National Front for the Liberation of South Vietnam (abbreviated NLF but also known as the Việt Cộng) by North Vietnam, which initiated an organized and widespread guerrilla insurgency against the South Vietnamese government. Hanoi directed the insurgency, which grew in intensity. The United States, under President Eisenhower, initially sent military advisers to train the South Vietnamese Army. As historian James Gibson summed up the situation: "Strategic hamlets had failed…. The South Vietnamese regime was incapable of winning the peasantry because of its class base among landlords. Indeed, there was no longer a 'regime' in the sense of a relatively stable political alliance and functioning bureaucracy. Instead, civil government and military operations had virtually ceased. The National Liberation Front had made great progress and was close to declaring provisional revolutionary governments in large areas." President John F. Kennedy increased the size of the advisory force fourfold and allowed the advisers to participate in combat operations, and later acquiesced in the removal of President Diệm in a military coup.

After promising not to do so during the 1964 election campaign, in 1965 President Lyndon B. Johnson decided to send in much larger numbers of combat troops, and conflict steadily escalated to become what is commonly known as the Vietnam War. In 1968, the communist Viet Cong ceased to be an effective fighting organization after the Tet Offensive and the war was largely taken over by regular army units of North Vietnam. In Paris, President Thiệu, who had not even been informed of the secret negotiations between the U.S and North Vietnam, was presented with the draft of the new agreement, he was furious with Kissinger and Nixon (who were perfectly aware of South Vietnam's negotiating position) and refused to accept it without significant changes. He then made several public radio addresses, claiming that the proposed agreement was worse than it actually was. However, Nixon ordered a halt to bombings north of the 20th parallel on 30 December 1972. With the U.S. committed to disengagement (and after threats from Nixon that South Vietnam would be abandoned if he did not agree), Thiệu had little choice but to accede. South Vietnam was pressurized into accepting an agreement that virtually ensured its collapse.

Following American withdrawal from the war in 1973, the South Vietnamese government continued fighting the North Vietnamese, until, overwhelmed by a conventional invasion by the North, it finally unconditionally surrendered on 30 April 1975, the day of the surrender of Saigon. North Vietnam controlled South Vietnam under military occupation, while the Provisional Revolutionary Government of the Republic of South Vietnam, which had been proclaimed in June 1969 by the North-controlled Viet Cong, became the nominal government. The North Vietnamese quickly moved to marginalise non-communist party members of the PRG and integrate South Vietnam into the communist North. The unified Socialist Republic of Vietnam was inaugurated on 2 July 1976.

The Embassy of the Republic of Vietnam in Washington donated 527 reels of South Vietnamese-produced film to the Library of Congress during the embassy's closure following the Fall of Saigon, which are in the Library to this day.

Specially, from 1952 to 1975 South Vietnam was an observer of the United Nations while the North was not.

The patch (1955-1975) of the South Vietnamese Airborne Division

A group of South Vietnamese troops celebrated victory after repelling North Vietnamese communist troops at An Loc, 1972.

The Republic of Vietnam Military Forces (RVNMF; Vietnamese: Quân lực Việt Nam Cộng hòa – QLVNCH), was formally established on 30 December 1955. Created out from the Vietnamese National Army of the State of Vietnam (1949-1955). The armed forces of the new state consisted in the mid-1950s of ground, air, and naval branches of service, respectively:

• Army of the Republic of Vietnam (ARVN)
• Republic of Vietnam Air Force (RVNAF)
• Republic of Vietnam Navy (RVNN)
• Republic of Vietnam Marine Division (RVNMD)

Their roles were defined as follows: to protect the sovereignty of the free Vietnamese nation and that of the Republic; to maintain the political and social order and the rule of law by providing internal security; to defend the newly independent Republic of Vietnam from external (and internal) threats; and ultimately, to help reunify Vietnam.

The French ceased training the QLVNCH in 1956 and training passed to American advisers who progressively restructured the military along US military lines.

The country was divided from north to south into four corps tactical zones: I Corps, II Corps, III Corps, IV Corps and the Capital Military District in and around Saigon.

At the time of signing of the Paris Peace Accords, the South Vietnamese government fielded the fourth largest military force in the world as a result of the American Enhance and Enhance Plus programs with approximately one and one-half million troops in uniform. The lack of sufficient training and dependence on the U.S. for spare parts, fuel, and ammunition caused maintenance and logistical problems. The impact of the 1973 oil crisis, a faltering economy, inflation and reduced US aid led to a steady decline in South Vietnamese military expenditure and effectiveness.

The ARVN always had problems keeping men in the ranks, but during 1973–75, the problem reached epidemic proportions. During 1974, for example, only 65 percent of authorized manpower was present for duty at any time. The nation's officer corps still suffered from the promotion and retention of generals due to their political loyalties, not their professional abilities. Corruption and incompetence among officers was endemic, with some "raising it almost to an art form."

South Vietnamese Marines boarded HMM-164 CH-46 to join the offensive in the Second Battle of Quảng Trị, 28 June 1872.

In 1972, General Creighton Abrams fumed at ARVN complaints that they lacked arms and equipment. He likewise harangued President Nguyen Van Thieu and chief of staff General Cao Van Vien: "Equipment is not what you need. You need men that will fight... You've got all the equipment you need... You lost most of your artillery because it was abandoned."

South Vietnam maintained a capitalist free-market economy with ties to the West. It established an airline named Air Vietnam in 1951. In 1953, notes (dated 1952) were introduced by the Institut d'Emission des Etats du Cambodge, du Laos et du Vietnam in denominations of 1, 5, 10, 100 and 200 đồng for South Vietnam. On 22 September 1955, the Ministry of Finance and Economic Affairs announced that notes from the Bank of Indochina and the Institut d'Emission issues for Cambodia and Laos would be exchanged for Institut d'Emission issues for Vietnam starting 30 September until 7 November. The Institut issues for Cambodia and Laos ceased to be legal tender on 7 October, and all Bank of Indochina notes lost their legal tender status on 31 October following the 15 October introduction of the first notes from the National Bank of Vietnam.

When the republic was established in South Vietnam on 26 October 1955, there were a few industrial facilities left over from the French colonial period, including some tobacco factories, beverages and alcohol, two sugar processing factories (Hiệp Hòa and Khánh Hội), a few machinery factories, and Michelin rubber processing plants. The government of Ngô Đình Diệm carried out a policy of export-oriented industrialization to replace imported goods and set up trade protectionism, tariff and non-tariff barriers were created to protect light industrial businesses. The result of this policy brought about the first paper factory of Vietnam, An Hao Paper Factory (1961) in Bien Hoa which supplied 30-40% domestic paper demand. Saigon served as the financial, industrial and transport centre of the Republic of Vietnam.

The economy was greatly assisted by American aid and the presence of large numbers of Americans in the country between 1961 and 1973 during Vietnam War. Electrical production increased fourteen-fold between 1954 and 1973 while industrial output increase by an average of 6.9 percent annually. South Vietnam had a small industrial sector and fell far behind other countries in the region in this respect. Output increased 2.5 to 3 times over the 20 years of the country's existence, but the share in total GDP remained at only around 10%, even dropping to 6% in some years, while the economy was dominated by strong agricultural and service sectors. Industrial production was highly dependent on imported inputs (some as part of aid programs) and mostly oriented towards local markets, while exports were dominated by agricultural and sea products. Over the 20 years of the existence of the Republic of Vietnam, the share of services in the economy grew from around 45% to 50-60%. Food processing and textiles became the largest industries by 1967, both having increased their capital ten-fold and employing over 17000 workers each. Other important industries included paper, rubber, basic chemicals, and cement. After 1965 industry suffered from escalating warfare and increasing inflows of American consumer goods. Some industries were able to continue growing rapidly, including food processing, wood processing, construction materials, and metals. By 1973 food processing was by far the largest industry in terms of output (almost half of the total industrial output of 448 billion dong), followed by textiles (around 1/5 of total output, but the largest employer with 32,489 out of 111,964 workers) and chemicals (1/10) (in terms of capital, electricity was the largest industry). Industry was highly concentrated in Saigon, Biên Hòa, Gia Định, with these three accounting for 85% of industrial companies and 90% of manufacturing output.

During the same period, rice output increased by 203 percent and the number of students in university increased from 2,000 to 90,000. US aid peaked at $2.3 billion in 1973, but dropped to $1.1 billion in 1974. Inflation rose to 200 percent as the country suffered economic shock due to the decrease of American aid as well as the oil price shock of October 1973.

A 2017 study in the journal Diplomatic History found that South Vietnamese economic planners sought to model the South Vietnamese economy on Taiwan and South Korea, which were perceived as successful examples of how to modernize developing economies. However, political conflicts and unrests (armed conflicts between factions, continuous coup d'état) confined the efficiency of those policies. Economic relations between the Saigon government and the communists were restored after the 1954 Geneva Accords. At one point there were minor commercial relations between the Saigon government in the South and the communists in the North, these interactions ceased in 1959, when political ties between the two sides deteriorated because the communists decided to use force in the South.

Demographics

South Vietnam population density map (left) and South Vietnamese ethnic map (right), 1972

In 1968, the population of South Vietnam was estimated to be 16,259,334.

Vietnamese was the official language and was spoken by the majority of the population. Despite the end of French colonial rule in Vietnam in 1954, the French language maintained a strong presence in South Vietnam where it was used in administration, education (especially at the secondary and higher levels), trade and diplomacy as a national language. The ruling elite of South Vietnam spoke French. Due to its special relationship with France, South Vietnam became a member of the Organisation internationale de la Francophonie in 1970, its membership was later inherited by unified communist Vietnam in 1979. With US involvement in the Vietnam War, English was also later introduced to the armed forces and became a secondary diplomatic language. Languages spoken by minority groups included Chinese, Khmer, Cham, and other languages spoken by Montagnard groups.

Starting from 1955, the South Vietnamese government of Ngô Đình Diệm carried out an assimilation policy towards indigenous peoples (Montagnard) of the Central Highlands and the Cham people, including banning the Cham language in public schools, seizing indigenous lands and granting them to mostly Catholic Northern Kinh people who had moved to South Vietnam during Operation Passage to Freedom. This resulted in increasing nationalism and support for independence among the Cham and other indigenous peoples. Some Cham joined the communist Viet Cong, some others joined the Front de Libération des Hauts Plateaux du Champa. By 1964, civil rights activists and independent organizations of the indigenous peoples, including Cham organizations, had been merged into the Front Unifié de Lutte des Races Opprimées (FULRO), which struggled against both the governments of North and South Vietnam, as well as the succeeding Socialist Republic of Vietnam until 1992. There were some industrial businesses run by local Chinese, including textiles, food processing, while local Vietnamese people had only workshop-size industrial activities. However, President Ngô Đình Diệm issued a series of measures between 1955 and 1956 to integrate the ethnic Chinese into South Vietnamese society.

The majority of the population identified as Buddhists. Approximately 10% of the population was Christian, mainly Catholic. Other religions included Caodaism and Hoahaoism. Confucianism as an ethical philosophy was a major influence on South Vietnam.

Culture

South Vietnam winning gold at the 1959 SEA Games. During its existence (1949-1975), South Vietnam joined FIFA (in 1952) and the AFC while the North did not. Vietnam unifying in 1976 is classified as its successor by FIFA.

Saigon University, 1961

Cultural life of Vietnam was strongly influenced by China until the French colonial period. At that time, the traditional culture began to acquire an overlay of Western characteristics. Many families had three generations living under one roof. The emerging South Vietnamese middle class and youth in the 1960s became increasingly more Westernised, and followed American cultural and social trends, especially in music, fashion and social attitudes in major cities like Saigon.

Music

Yellow Music (Nhạc vàng) refers to music produced in South Vietnam, especially after the country was divided; and it also refers to South Vietnamese flag being mostly yellow, named in opposition to "Red Music" (Nhạc đỏ) endorsed by the communist government of North Vietnam. The genre contained topics and characteristics considered decadent and was banned in 1975, with those caught listening to it punished, and their music confiscated. Most Yellow Music has been associated with the bolero genre. After the Fall of Saigon, many Vietnamese artists emigrated to the United States to pursue their careers and industry there instead. The ban on Yellow Music was lightened in 1986, but by then the music industry had ceased to exist.

In the 1990s, Vietnam's Ministry of Culture, Sports and Tourism promoted the "nhạc xanh" genre (literally "green music", which refers to music for young generations) to divert people from listening to yellow music, but with little success.

At the beginning of the 21st century, various yellow music concerts were held in Vietnam. In August 2010, two singers – Hương Lan and Tuấn Vũ – performed at the Hanoi Opera House for half a month.

Media

There were four AM and one FM radio stations, all of them owned by the government (VTVN), named Radio Vietnam. One of them was designated as a nationwide civilian broadcast, another was for military service and the other two stations included a French-language broadcast station and foreign language station broadcasting in Chinese, English, Khmer and Thai. Radio Vietnam started its operation in 1955 under then President Ngo Dinh Diem, and ceased operation on 30 April 1975, with the broadcast of surrender to the North Vietnamese army by South Vietnamese president Duong Van Minh. The radio stations across the former South were later reused by the communist regime to broadcast their state-run radio service.

Television

Television was introduced to South Vietnam on 7 February 1966 with a black-and-white FCC system. Covering major cities in South Vietnam, started with a one-hour broadcast per day then increased to six hours in the evening during the 1970s. There were two main channels:

• THVN-TV (Truyền hình Việt Nam-TV) on Channel 9, featuring Vietnamese-language shows, news, and special announcements from Saigon. This entirely Vietnamese language channel catered to the Vietnamese populace. In Los Angeles during the 1980s, some former technicians re-established THVN9 to broadcast news and dramas by Vietnamese language for service to the Vietnamese American community. It was the first television broadcaster in Vietnam. From 1972, all important events were broadcast in color as standard. Its final programming aired the evening of April 29, 1975.

• AFVN-TV on Channel 11, operated by Armed Forces Radio and Television Service (now American Forces Network), catered to US troops in South Vietnam. Broadcasting entirely in English, it relayed popular US-made shows like The Ed Sullivan Show and The Tonight Show Starring Johnny Carson, and various sports games like the World Series. It also broadcast news and special announcements from the American government and military commanders.

Both channels used an airborne transmission relay system from airplanes flying at high altitudes, called Stratovision.
