State of Vietnam

The State of Vietnam (Vietnamese: Quốc gia Việt Nam; chữ Hán: 國家越南; French: État du Viêt-Nam) was a state in Southeast Asia that existed from 1949 until 1955, first as an associated state of the French Union and later as an independent state (from 20 July 1954 to 26 October 1955). The state claimed authority over all of Vietnam during the First Indochina War, although large parts of its remote territory were controlled by the Democratic Republic of Vietnam.

The State of Vietnam was formed in 1949 within the framework of the French Union as a compromise between Vietnamese nationalists and the French, in opposition to the communists. It gained international recognition in 1950 and aligned politically with the Western Bloc. Former emperor Bảo Đại became Chief of State. Following the 1954 Geneva Accords between the communist Viet Minh and the French, the State of Vietnam lost its remaining foothold in the northern half of the country, where most rural areas were already controlled by the Viet Minh. Ngô Đình Diệm was appointed prime minister the same year and—after having ousted Bảo Đại in 1955—became president of the Republic of Vietnam.

The 16th parallel was established by the Allies on August 2, 1945, following the Potsdam Conference, dividing the former French Indochina into two military zones: Chinese Nationalist forces occupied the North, and British forces the South, to disarm Japanese troops. The communist-led Viet Minh launched the August Revolution to seek control in Vietnam, and Ho Chi Minh declared the independence of the Democratic Republic of Vietnam (DRV).

Beginning in August 1945, the Viet Minh sought to consolidate power by terrorizing and purging rival Vietnamese nationalist groups and Trotskyist activists. On September 23, the British supported a French coup de force that overthrew the DRV government in Saigon and attempted to reinstate French control over southern Indochina. In 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. That summer, the Viet Minh colluded with French forces to eliminate nationalists, targeted for their ardent anti-colonialism.

With most of the nationalist partisans defeated, and negotiations broken down, tensions between the Viet Minh and French authorities erupted into full-scale war in December 1946, a conflict which became entwined with the Cold War. Surviving nationalist partisans and politico-religious groups rallied behind the exiled Bảo Đại to reopen negotiations with France in opposition to communist domination.

On June 5, 1948, the Halong Bay Agreements (Accords de la baie d’Along) allowed the foundation of a unified Vietnamese government replacing the governments of Tonkin (North Vietnam) and Annam (Middle Vietnam) associated to France within the French Union. The Associated States of Indochina then also included the neighboring Kingdom of Laos and Kingdom of Cambodia. Cochinchina (South Vietnam), however, had a different status, both as a colony and as an autonomous republic, and its reunification with the rest of Vietnam had to be approved by its local assembly, and then by the French National Assembly. During the transitional period, a Provisional Central Government of Vietnam was proclaimed: Nguyễn Văn Xuân, until then head of the Provisional Government of South Vietnam (as Cochinchina had been known since 1947), became its president, while Bảo Đại waited for a complete reunification to take office.

On May 20, 1949, the French National Assembly approved the reunification of Cochinchina with the rest of Vietnam. The decision took effect on June 14 and the State of Vietnam (SVN) was officially proclaimed on July 2. From 1949 to 1954, the State of Vietnam had partial autonomy from France as an associated state within the French Union.

Bảo Đại and Hồ Chí Minh competed for international and domestic recognition as the legitimate authority over Vietnam. While the State of Vietnam aligned with the anticommunist Western Bloc, the French exploited it to extend their colonial presence and to bolster their standing within NATO. The State of Vietnam received its strongest support from the United States while Hồ's DRV was backed by the People's Republic of China and the Soviet Union (since 1950).
