Hồ Chí Minh's leadership (1945–1960) Proclamation of the republic After nearly three centuries of partition by feudal dynasties, Vietnam was again under one single authority in 1802 when
Gia Long founded the
Nguyễn dynasty, but the country became a French
protectorate after 1883 and under
Japanese occupation after 1940 during
World War II. US President
Franklin D. Roosevelt was opposed to a return to French rule in Indochina, and proposed placing the region under
United Nations trusteeship. Soon after
Japan surrendered, the Việt Minh in the
August Revolution entered
Hanoi, and the Democratic Republic of Vietnam was proclaimed on 2 September 1945 establishing independence and a new government for the country, replacing the Nguyễn dynasty.

Early periods The Democratic Republic of Vietnam claimed sovereignty over all of Vietnam, but during this time, several areas, particularly in the South, were not aligned with the Viet Minh. The successive collapse of French, then Japanese power, followed by the disputes among the political factions, had been accompanied by widespread violence in the countryside. On 12 September 1945, the first British troops arrived in Saigon, and on 23 September 1945, French troops occupied the police stations, the post office, and other public buildings. In the north, the
Chinese Nationalist Army arrived to disarm the Japanese, and the Chinese presence had forced Hồ Chí Minh and the Việt Minh to accommodate Kuomintang-supported Vietnamese nationalists. After the departure of the British in 1946, the French controlled the urban regions of Vietnam south of the 16th parallel following the
Southern Resistance War. Meanwhile, the Viet Minh sought to consolidate power by terrorizing and purging rival Vietnamese
nationalist groups and
Trotskyist activists. In January 1946, the Việt Minh held
an election, mainly in the North, to establish a National Assembly. There were few competitive races and the party makeup of the Assembly was determined in advance of the vote. Former Prime Minister
Trần Trọng Kim claimed there were places where people were forced to vote for the Việt Minh. Rumors of secret negotiations with the French were putting the Viet Minh at a disadvantage. In late February, gripped by despair, Hồ went so far as to ask Bảo Đại to take over the government. Before Bảo Đại could reach a decision, however, Hồ changed his mind after receiving assurances from the Chinese that they would pressure the nationalist parties to join the new government. The
Vietnamese Nationalist Party (Việt Quốc) and the
Vietnam Revolutionary League (Việt Cách) then accepted 70 assigned seats in the National Assembly, allowing the DRV to present the appearance of an inclusive government. In March 1946, the Franco-Chinese and
Ho–Sainteny Agreements enabled French forces to replace the Chinese north of the
16th parallel and facilitated a coexistence between the DRV and the French that strengthened the Viet Minh while undermining the nationalists. In June, Chinese Nationalist troops evacuated Hanoi, and on 15 June, the last detachments embarked at Haiphong. With the Chinese Kuomintang withdrawal,
Võ Nguyên Giáp resolved that the Viet Minh must consolidate full control of the government and promptly moved to secure a monopoly of power for the movement. That summer, the Viet Minh colluded with French forces to eliminate Vietnamese nationalists, targeted for their ardent anti-colonialism. It was reported that a force of about 13,000 nationalists was destroyed in
Tonkin. Another estimate indicates that 15,000 were massacred across northern Vietnam. When France declared
Cochinchina, the southern third of Vietnam, a separate state as the "Autonomous Republic of Cochinchina" in June 1946; Vietnamese nationalists reacted with fury. In November 1946, the DRV's
National Assembly adopted the first constitution.

Hai Phong incident and the deterioration of the
Fontainebleau Agreements, the French
reoccupied Hanoi and the
First Indochina War (1946–54) followed, during which many urban areas fell under French control. Following the
Chinese Communist Revolution (1946–50), Chinese communist forces arrived on the border in 1949. Chinese aid revived the fortunes of the Viet Minh and transformed it from a guerrilla militia into a
standing army. The outbreak of the
Korean War in June 1950 transformed what had been an anti-colonial struggle into a
Cold War battleground, with the U.S. providing financial support to the French. The DRV became increasingly radicalized in 1948 as
Indochinese Communist Party (ICP) leaders began looking beyond independence toward building a
socialist regime. At its accession, the DRV state had accommodated urban elites, the colonial-trained bureaucracy, former officials of the Empire of Vietnam, and local mass organizations. However, these compromises fell apart in 1948 as internal conflict between communist and non-communist leaders escalated at many levels of government. The ICP valued its political cadres and distrusted educated professionals, managers, and intellectuals. Following the establishment of the
Cominform and the
Chinese Communist Party's victories in areas where Mao Zedong attributed success to the mobilization of landless peasants, the DRV adopted a more aggressive land policy. Although the ICP expanded rapidly, with its membership surging from 5,000 in late 1945 to about 180,000 by the end of 1948, the radical vision of ICP leaders met opposition among party members, who were mostly from the middle peasantry and higher social classes. Communist leaders resolved to eradicate
judicial independence entirely. As Trường Chinh indicated, it was "now time for the Indochinese revolution to show its true colours," 1948 thus marked an irreversible, proletarian turn of the DRV toward a
communist revolution. With communist leaders no longer concealing their social revolutionary agenda and Chinese guidance, the DRV underwent further radicalization, including rectification () campaigns to indoctrinate party members, soldiers, and government personnel in communist ideology. This process of radicalization, in which
land reform was the latest and most radical, provoked widespread disillusionment and large-scale defections from the maquis to areas controlled by the French and the
State of Vietnam (SVN), a phenomenon known as
dinh tê. Among the defectors were numerous intellectuals, teachers, landlords, civil servants, soldiers, and cadres, including
Phạm Duy,
Trần Chánh Thành,
Trần Ngọc Châu, and
Nguyễn Văn Thiệu. Some joined the SVN, others entered existing anticommunist groups, and still others supported anticommunist nationalism in principle but adopted an
attentiste (wait-and-see) stance. In the meantime, with Chinese communists' assistance, Giáp built and unleashed a remarkably modern army against the French in the decisive
Battle of Dien Bien Phu in 1954.
Provisional military demarcation of Vietnam Following the partition of Vietnam in 1954 at the end of the
First Indochina War, more than one million North Vietnamese migrated to South Vietnam, many under the US-led evacuation campaign named
Operation Passage to Freedom, with an estimated 60% of the north's one million Catholics fleeing south. The Catholic migration is attributed to an expectation of persecution of
Catholics by the North Vietnamese government, as well as publicity employed by the Saigon government of the Prime Minister
Ngo Dinh Diem. The CIA ran a propaganda campaign to get Catholics to come to the south. However Colonel
Edward Lansdale, the man credited with the campaign, rejected the notion that his campaign had much effect on popular sentiment. The Viet Minh sought to detain or otherwise prevent would-be refugees from leaving, such as through intimidation through military presence, shutting down ferry services and water traffic, or prohibiting mass gatherings. Concurrently, between 14,000 and 45,000 civilians and approximately 100,000 Viet Minh fighters moved in the opposite direction.
Lê Duẩn's leadership (1960–1976) Vietnam War During 1962, North Vietnam intensified its war efforts by infiltrating military personnel and materiel into South Vietnam. Meanwhile, Beijing, following the
Sino-Soviet split and rejecting Moscow's policy of "peaceful coexistence" with the West, backed Hanoi's escalation by providing the
Viet Cong with vital small arms and heavier weaponry.
Reunification After the
fall of Saigon on 30 April 1975, the
Provisional Revolutionary Government of the Republic of South Vietnam, or the
Việt Cộng, alongside the
North Vietnamese Army, governed South Vietnam for the next year. However it was seen as a vassal government of North Vietnam. North and South Vietnam were officially reunited on 2 July 1976 as the
Socialist Republic of Vietnam. The merged country's government was dominated by holdovers from North Vietnam, and adopted the North Vietnamese constitution, flag and anthem. == Government and politics ==
