    Key Facts And Information

    Let's know more about Ngo Dinh Diem!

    • Ngô Đình Diệm was a Vietnamese politician supported by the United States. He became the final prime minister of the State of Vietnam 1954-55.
    • Ngo Dinh Diem (3 January 1901-2 November 1963) served as President of South Vietnam from 1955 until he was killed during the 1963 military coup, also supported by the United States.
    • He was born into one of the noble families of Vietnam. His ancestors were among the first Vietnamese who converted to Roman Catholicism.
    • Even from the beginning of his youth, he was on friendly terms with the imperial family, later serving as Minister of Interior for Emperor Bao Dai.
    • His Catholicism made him favour fellow Vietnamese Roman Catholics while at the same time he discriminated Buddhists.
    • Diem would often imprison or kill those who opposed his regime.
    • Diem's discrimination against Buddhists persuaded the United States and the Army of the Republic of Vietnam to withdraw their support for him, leading to his assassination.
    • In 1955, he proclaimed the creation of the Republic of Vietnam and became the first president of the newly created republic.
    • He supported Vietnamese nationalism, promoting an anti-communist and anti-colonialist "third way" opposed to both Bao Dai and communist leader Ho Chi Minh.
    • Diem established the Can Lao Party to support his political doctrine of Person Dignity Theory.
    • He is a controversial figure, historians consider him a tool for the United States, while others portray him as an avatar of Vietnamese tradition.

    • While he is usually referred to as Diệm in English, his family name is Ngô.
    • The assassination of Ngo Dinh Diem occurred twenty days before the assassination of John F. Kennedy.


    • The crumbling of the French Empire in Southeast Asia would create the eventual states of North Vietnam and South Vietnam. South Vietnam was a state and member of the French Union that claimed authority over all of Vietnam during the First Indochina War, however, large parts of its territory were controlled by the communist Democratic Republic of Vietnam of the Viet Minh or North Vietnam.

    • The Viet Minh was a national independence coalition formed by Ho Chi Minh in 1941 and was an anti-French and anti-Japanese group. They sought independence from France and for the whole of Vietnam. France was backed up by the United States who would then backup the Viet Minh against the Japanese. Later, the Viet Minh took control of North Vietnam through the Geneva Agreements and opposed South Vietnam and the United States.
    • South Vietnam was a state created in 1949 by France and internationally recognised in 1950. Former Emperor Bao Dai became Chief of State, and after the 1954 Geneva Agreements, South Vietnam had to abandon the northern part of the country to the Democratic Republic of Vietnam. Ngo Dinh Diem was appointed prime minister in 1954, and after ousting Bao Dai in 1955, he became President of the Republic of Vietnam with the backing of the United States.

    Ho Chi Minh

    • Ho Chi Minh was the Prime Minister of North Vietnam from 1945 to 1955 and the President from 1945 to 1969.
    • Ho Chi Minh (19 May 1890 - 2 September 1969) was the Vietnamese Communist leader who led the People's Army of Vietnam and the Vietcong during the Vietnam War. He served as the Prime Minister of the Democratic Republic of Vietnam from 1945-1955 and its President from 1945-1969.

    Ngo Dinh Diem

    • Born in 1901 in central Vietnam, Ngo Dinh Diem's family originated from Phu Cam Village, a Catholic village near Hue City. His family had been among the first to convert to Catholicism in the 17th century. The family suffered under the anti-Catholic persecutions of Emperors Minh Mang and Tu Duc.

    • Diem's father was educated in a Catholic school in British Malaya, where he learned English and studied European culture. Despite being a devout Catholic, he scrapped plans to become a Roman Catholic priest in the late 1870s. He worked for the commander of the French armed forces as an interpreter and took part in campaigns against anti-colonial rebels. He soon became a high-ranking Mandarin and a counsellor to Emperor Thanh Thai under the French colonial regime. He wanted to make sure his children were well educated in both Christian and Confucian classics.
    • During his childhood, Diem laboured in the rice fields while studying at a French Catholic school, and later entered a private school started by his father. Diem's elder brother, Ngo Dinh Thuc, went into seminary and later became Vietnam's highest-ranking Catholic bishop. Due to his family's background, education and especially Catholicism and Confucianism, Diem would show off these influences in his later life, especially in his career and politics.


    • During his career as a Mandarin, Diem formed a reputation for being a workaholic, incorruptible, nationalist Catholic leader. Catholic nationalism in Vietnam during the 1920s and 1930s facilitated Diem's ascent in his bureaucratic career. His rise was also facilitated through his brother's marriage to the daughter of the Catholic head of the Council of Ministers at the Hue court.
    • Nguyen Huu Bai, the Minister of the Interior of the Royal Court, was highly impressed by Diem's religious and family ties and thus became his patron. Upon encountering communists distributing propaganda, he was revolted and started distributing his own pamphlets and engaged in anti-communist activities.

    • In 1929, Diem was promoted to the governorship of Binh Thuan Province. In 1930-1931 he helped the French to suppress peasant revolts organised by communists. With the ascension of Bao Dai to the throne in 1933, Diem received an invitation to become his interior minister. He accepted but after his proposals for reforms were rejected, he resigned. Diem denounced Emperor Bao Dai as a puppet for the French.
    • The French threatened Diem with arrest and exile. For the next decade, he conducted extensive nationalist activities, and corresponded with various Vietnamese revolutionaries such as his friend Phan Boi Chau, a Vietnamese anti-colonial activist whom Diem greatly respected. They concluded that Confucian teachings could be applied to modern Vietnam. World War II started and Diem saw an opportunity for Vietnam to challenge French colonisation. He tried to establish relationships with the Japanese and formed a secret political party.

    • The secret political party was named the Association for the Restoration of Great Vietnam but its existence was discovered in 1944 and the French ordered Diem's arrest. He fled to Saigon under Japanese protection where he would remain until the end of the war. Ho Chi Minh proclaimed the Democratic Republic of Vietnam, and in the northern half of Vietnam, his Viet Minh began fighting the French. Diem wanted to dissuade Bao Dai from joining Ho Chi Minh but was captured by the Viet Minh and exiled again. Later, he was taken to Ho Chi Minh where he received an offer from him to become a minister but Diem declined.
    • In this period of time, Diem and the other non-communist nationalists faced a dilemma: They didn't want to restore colonial rule nor wished to support the Viet Minh. As such, Diem declared his neutrality and attempted to establish a Third Force movement that would be both anti-colonialist and anti-communist. He united non-communist Vietnamese and also maintained secret contact with high-ranking leaders of the Democratic Republic of Vietnam in an attempt to persuade them to leave Ho Chi Minh's side and join his.

    • Bao Dai signed an agreement to grant Vietnam status as an "associate state" within the French Union, much to Diem's disappointment. The French then created the State of Vietnam and Diem refused to become Bao Dai's prime minister. He publicly declared in newspapers his manifesto about a third force opposite the Viet Minh and Bao Dai, but few people showed interest in it and the Viet Minh and French now knew that he was a threat. A couple of failed assassination attempts forced Diem to flee into exile yet again.


    • Diem travelled to Japan and Rome. In Japan, he met with Prince Cuong De, a former ally, and they discussed their efforts concerning Vietnam. Cuon De introduced Wesley Fishel to Diem. He was an American working for the CIA. Fishel was a proponent of the anti-colonial, anti-communist third force doctrine in Asia. He helped Diem organise connections in the United States and, in 1951, Diem went there. The Americans' assessment of Diem was varied, however, he gained favour with high-ranking officials such as William Douglas, Francis Spellman, John F. Kennedy, the legendary spy chief of the CIA William J. Donovan, and many others. These connections would help him in the future.

    Return to Power

    • Following the Geneva Conference in 1954, Diem met with Bao Dai and agreed to be the Prime Minister if he received military and civilian control. Diem was successful and established his new government. He criticised the French for abandoning North Vietnam to the Communists at Geneva.
    • Diem faced a lot of challenges in his new position: His enemies where everywhere and they were helped by the French who wanted to remove him from power. However, Diem established the National Bank of Vietnam, attacked his enemies, defeated Binh Xuyen and, thus, marked the end of French interference and plots to remove him.

    • According to Miller, Diem's capacity in subduing his enemies and consolidating power strengthened US support of his government. A referendum was soon scheduled in 1955 that would determine the direction of South Vietnam. Diem and Bao Dai participated in elections for presidency.
    • Supporters of Diem used propaganda to destroy Bao Dai's reputation, stopped his supporters from voting and, when the official results of the votes came in, they were clearly fraud. This is when Diem proclaimed the Republic of Vietnam, with himself as its first President.
    • The Can Lao Party played a key role in Diem's regime and, when necessary they would assume the role of the government. According to Miller, democracy to Diem was rooted in his dual identity as Confucian and Catholic and was associated with communitarianism and the doctrine of Personalism.

    • However, Diem's regime of "democratic one-man rule" faced increasing difficulties. After pressures from both the United States and Vietnam, he agreed to hold legislative elections. However, Diem applied censorship of the press, candidates faced harassment and intimidation, leaving no chance for anyone to step into his shoes. US Vice President L.B. Johnson visited Saigon and declared Diem the "Winston Churchill of Asia".
    • During his presidency, Diem imposed programmes to reform Saigon society, specifically:
      • Brothels and opium dens were closed
      • Divorce and abortion were made illegal
      • Adultery laws were strengthened
    • Many schools and universities were established and the preservation of Vietnamese traditional culture was preserved.
    • In the economic section, key factors were pointed out, a developed economy, support for local capitalists, stabilised currency, reduced budget deficits, and enhanced building infrastructure.
    • In 1957, Diem's government suggested the 5-year plan, which aimed at expanding cultivated area to 20% and improving agricultural production to 25%. The government also encouraged the development of handicrafts, industry, commerce and other actions to diminish the role of foreign capitalists and enhance the role of indigenous capitalists. While making these reforms, Diem also concentrated on eliminating communists.

    Persecutions and demise

    • Come 1963, Diem's methods had made him unpopular amongst the Southern Vietnamese as his policies did not help the economy of Vietnam. Furthermore, his oppression of Buddhists led to the Hue Phat Dan shootings on 8 May 1963, which killed 9 unarmed Buddhist civilians. This event provoked widespread condemnation of his government.
    • Thousands of people were killed by Diem's secret police, even if they were just suspected of being communists. There were many assassination attempts on Diem, but he managed to protect himself. The way in which he handled the communists created a sense of fear in the general public and the US slowly started to drift away from him. The administration of John F. Kennedy ultimately decided to have Diem deposed in late 1963, because of the Buddhist crisis. A couple of months before Diem's overthrow, Buddhists celebrating the Buddha's birthday in Hue were ordered to take their religious flags down.

    • There was a government decree that implied that only the national flags could be flown in South Vietnam. The protesting Buddhists pointed out that Diem's brother, Ngo Dinh Thuc, the Archbishop of Vietnam, was recently celebrated with papal banners. This appeared to be more evidence of the administration's pro-Catholic anti-Buddhist bias. Diem did nothing about this, and another protest in Hue ensued that resulted in a massacre. Government troops fired upon the crowd, people and children were run over by tanks.
    • More protests ensued and more people were either arrested or killed until one incident put an end to it. A monk by the name of Thich Quang Duc burned himself alive while other monks and nuns stopped the police from getting close to him. Malcolm Brown, an American photographer, captured this moment and the monk became a martyr because of the government's lack of concern.
    • Although Diem hung onto power for a few more months, this is the moment that led to his demise. This wasn't an isolated incident - a growing number of Buddhist monks and nuns followed Thich Quang Duc's example and burned themselves alive in protest. Finally, in November 1963, a cabal of generals rose up and overthrew Diem. Diem and his brother were shot and stabbed repeatedly and then their bodies were buried in an unmarked grave.


    • South Vietnam was unable to establish a stable government after Diem's assassination. Several coups took place after his death while the United States continued to influence South Vietnam's government. The assassination bolstered North Vietnam's attempts to characterise the South Vietnamese as "supporters of colonialism."
    • Upon Diem's death, the regime collapsed and marked the end of the First Republic of Vietnam. Some of Diem's contributions can, however, be appreciated, such as his part in resolving the northern refugee crisis, and the general pacification of the country. He had stabilised a South Vietnam that suffered through the First Indochina War and was now partially independent. The security and normalisation factors contributed to the creation of favourable conditions for the economy and the development of education, especially through the creation of universities that applied the methods of European and American-style vocational schools.
