Vietnam

Historical overview

Vietnam’s history includes periods of independent dynastic rule, Chinese domination, regional expansion, French colonialism, Japanese occupation, revolution, division and reunification. The Nguy–n dynasty, established in 1802, unified the country under the imperial court at Huế. French military intervention began in 1858, and France progressively established colonial control over Vietnam, Cambodia and Laos, which became French Indochina in 1887.

Vietnamese resistance movements developed throughout the colonial period. In 1941, H– Chí Minh and other nationalists established the Việt Minh coalition to pursue independence. Following Japan’s surrender in August 1945, the August Revolution brought the Việt Minh to power in Hanoi. On 2 September 1945, H– Chí Minh proclaimed the Democratic Republic of Vietnam.

France attempted to re-establish colonial authority, leading to the First Indochina War. The French defeat at Điện Biên Phủ in May 1954 and the Geneva Agreements of July 1954 ended the war and established a temporary military demarcation near the 17th parallel, pending elections intended to reunify the country. Those elections did not take place. The Democratic Republic of Vietnam governed the North, while the Republic of Vietnam was established in the South in 1955.

The Vietnam War expanded into a major international conflict. The Paris Peace Accords were signed on 27 January 1973. Saigon fell to North Vietnamese forces on 30 April 1975, and the country was formally reunified as the Socialist Republic of Vietnam on 2 July 1976.

In 1986, the Communist Party of Vietnam introduced the Đổi Mới reform programme, initiating major economic changes and a gradual opening to international trade and investment. Political power remains organised under the one-party socialist republic system. The historical archive should therefore include both the national independence and reunification narratives and research on political freedoms, post-war displacement, re-education, migration and human-rights concerns. archives.go.jp
