During the transitional period of relocation, at least 500,000 Catholics sailed South, many of them through

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.

(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

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 groupthe Cao Đài, Hòa Hảo and the Bình Xuyên organised crime syndicate whose military strength combined amounted to approximately 350,000 fighters.
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.[
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:

Kỳ and Thieu 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. The Parliamentary election took place on 22 October 1967.

North Vietnam launched a conventional invasion of South Vietnam in late March 1972 which was only finally repulsed by October with massive US air support.
1973–1975
In accordance with the Paris Peace Accords signed on 27 January 1973, 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
Nguyễn Chấn, known as Trần Văn Trà (15 September 1919 – 20 April 1996) was a colonel-general in the People's Army of Vietnam. He was Commander of B2 Front during 1963 – 1967, Deputy Commander of Liberation Army of South Vietnam dur ...
. 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 north of Saigon.
On 15 March 1973, 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

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.
In December 1974, the PAVN launched an invasion at Phuoc Long 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, in the first phase of what became known as the Ho Chi Minh Campaign. 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
Gerald Rudolph Ford Jr. (born Leslie Lynch King Jr.; July 14, 1913December 26, 2006) was the 38th president of the United States, serving from 1974 to 1977. A member of the Republican Party (United States), Republican Party, Ford assumed the p ...
, 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: April 1975
Morale was low in South Vietnam as the PAVN advanced. A last-ditch defense was made by the ARVN 18th Division at the Battle of Xuân Lộc from 9–21 April. Thiệu resigned on 21 April 1975, and fled to Taiwan

. 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. The North, however, was not interested in negotiations, and its forces captured Saigon. Minh unconditionally surrendered Saigon and the rest of South Vietnam to North Vietnam 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 carrier

, 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.][

Thieu quickly consolidated power much to the dismay of those who hoped for an era of more political openness.

Administrative divisions
Provinces
South Vietnam was divided into forty-four provinces:
Regions
Throughout its history South Vietnam had many reforms enacted that affected the organisation of its administrative divisions.
On 24 October 1956 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 coup d'état that ousted Diem 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 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 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.[''The Pentagon Papers'' (1971), Beacon Press, vol. 3, p. 140.] It provided for unification elections under the supervision of the United Nations

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 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 (commonly known as the Việt Cộng), 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''.

. In 1968, the NLF 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. 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 fall 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 NLF, became the nominal government. The North Vietnamese quickly moved to marginalise non-communist members of the PRG and integrate South Vietnam into the communist North. The unified Socialist Republic of Vietnam was inaugurated on 2 July 1976.

International organisations
South Vietnam was a member of Agence de Coopération Culturelle et Technique, accT, the Asian Development Bank (ADB), the World Bank (IBRD), the International Development Association (IDA), the International Finance Corporation (IFC), the International Monetary Fund, IMF, the International Telecommunications Satellite Organization (Intelsat), International Criminal Police Organization, Interpol, the International Olympic Committee, IOC, the International Telecommunication Union, ITU, the Red Cross, League of Red Cross and Red Crescent Societies (LORCS), United Nations Educational, Scientific and Cultural Organization, UNESCO and the Universal Postal Union (UPU).
Military
The Republic of Vietnam Military Forces (RVNMF; – QLVNCH), was formally established on 30 December 1955. Created out from ex-French Union
The French Union () was a political entity created by the French Fourth Republic to replace the old French colonial empire system, colloquially known as the " French Empire" (). It was ''de jure'' the end of the "indigenous" () status of Frenc ...
Army colonial Indochinese auxiliary units (French language, French: ''Supplétifs''), gathered earlier in July 1951 into the French-led Vietnamese National Army – VNA (Vietnamese language, Vietnamese: ''Quân Đội Quốc Gia Việt Nam'' – QĐQGVN), Armée Nationale Vietnamiènne (ANV) in French, the armed forces of the new state consisted in the mid-1950s of ground, air, and naval branches of service, respectively:
*ARVN, 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.
Conscription was practiced in South Vietnam but soldiers could join voluntarily also. However, enforcement of conscription was lax. Conscription began in 1957 initially requiring adult males who were 20 and/or 21 to serve for 18 months in the military. Rules would change over time in regards to military conscription.
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 (South Vietnam), I Corps, II Corps (South Vietnam), II Corps, III Corps (South Vietnam), III Corps, IV Corps (South Vietnam), 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 Operation Enhance Plus, 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.
Economy
South Vietnam maintained a capitalist free-market economy with ties to the West. It established an airline named Air 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.[Kim, Youngmin,]
The South Vietnamese Economy During the Vietnam War, 1954–1975
" 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.[Wiest, Andrew A., ''The Vietnam War, 1956–1975'', p. 80.] 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. The unification of Vietnam in 1976 was followed by the imposition of North Vietnam's centrally planned economy in the South.
A 2017 study in the journal ''Diplomatic History (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.
Demographics
In 1968, the population of South Vietnam was estimated to be 16,259,334. However, about one-fifth of the people who lived in Southern Vietnam (from Quang Tri Province to the South) lived in areas that were controlled by Viet Cong
The Viet Cong (VC) was an epithet and umbrella term to refer to the communist-driven armed movement and united front organization in South Vietnam. It was formally organized as and led by the National Liberation Front of South Vietnam, and ...
. In 1970 about 90% of population was Kinh (Viet), and 10% was Hoa people, Hoa (Chinese), Degar, Montagnard, French people, French, Khmer Krom, Khmer, Cham people, Cham, Eurasians and others.
Vietnamese was the official language and was spoken by the majority of the population. Despite the end of French colonial rule, 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. The ruling elite of South Vietnam spoke French.[ 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 language, Khmer, Cham language, 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 Viet Cong, some others joined the Front for the Liberation of Champa, 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 United Front for the Liberation of Oppressed Races, Front Unifié de Lutte des Races Opprimées (FULRO), which struggled against both the governments of South Vietnam and the succeeding Socialist Republic of Vietnam until the late 1980s.
The majority of the population identified as Buddhism, Buddhists. Approximately 10% of the population was Christianity, Christian, mainly Catholic Church, Catholic. Other religions included Caodaism and Hoahaoism. Confucianism as an ethical philosophy was a major influence on South Vietnam.]
Culture
Cultural life was strongly influenced by China until French domination in the 18th century. 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.
Media
Radio
There were four AM and one FM radio stations, all of them owned by the government (VTVN), named . 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 by 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.
*American Forces Network#Vietnam, AFVN-TV on Channel 11, operated by American Forces Network, 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.
