Tonkin (French protectorate)

In March 1945, the emperor Bảo Đại rescinded the Patenôtre Treaty, ending the French protectorates over Annam and Tonkin, establishing the Empire of Vietnam, a Japanese-backed state. Following the surrender of Japan, ending World War II, the Việt Minh launched the August Revolution which led to the abdication of Bảo Đại and the declaration of independence of the Democratic Republic of Vietnam.

Tonkin was briefly occupied by the Chinese National Army before the French took over following the Ho–Sainteny Agreement in March 1946. After eliminating virtually all nationalist oppositions, the communist-led Việt Minh clashed with the French over control of the territory. On 27 May 1948, Tonkin and Annam were partly merged under the Provisional Central Government of Vietnam. The French legally maintained the protectorate until they formally signed over sovereignty to Bảo Đại and the State of Vietnam in 1950 after the Élysée Accords took effect on 14 June 1949.

History

Establishment

After defeating the Vietnamese Nguyễn dynasty, the French colonised Southern Vietnam including Saigon in 1862 and 1867. Their sovereignty over here was recognized by the Vietnamese in 1874. Central and Northern Vietnam later became the French protectorates of Annam and Tonkin and French influence in the Indochina Peninsula strengthened. However unlike Cochinchina, these two territories were still parts of Vietnam legally. During the Sino-French War (1884–85), the northernmost part of Vietnam, Tonkin (then considered a crucial foothold in Southeast Asia and a key to the Chinese market), was invaded by the French. After the Treaty of Huế (1883) with Vietnam and the Treaty of Tientsin (1885) with the Chinese Qing dynasty, all of Vietnam was governed by the French.

During the French colonial administration, Vietnam was administratively divided into three different territories: Tonkin (in the north), Annam (in the centre), and the colony of Cochinchina (in the south). These territories were fairly arbitrary in their geographic extent as the vast majority of the Vietnamese regarded their country as a single land and minor resistance to French rule continued over the next 70 years to achieve an independent state. Annam and Tonkin were originally a single entity, the Résidence supérieure of Annam-Tonkin. On June 3, 1886, the Nguyễn emperor Đồng Khánh delegated all of his powers in Tonkin to a Kinh lược sứ (經略使, equivalent of Viceroy), who acted under French supervision. On May 9, 1889, the Résidence supérieure of Annam-Tonkin was abolished, with Annam and Tonkin being separated in two Résidences supérieures, each subordinated to the governor-general of French Indochina. On July 26, 1897, Governor-General Paul Doumer had Emperor Thành Thái abolish the post of Kinh lược sứ.The Nguyễn dynasty still nominally reigned over Tonkin; it was now de facto under direct French rule.

During French rule, Hanoi was made capital of Tonkin and, in 1901, of the whole French Indochina. Cities in Tonkin saw significant infrastructure and economic development under the French, such as the development of the port of Haiphong and construction of the Trans-Indochinois Railway linking Hanoi to Saigon. Under French economic plans, mines yielding gold, silver, and tin as well as the farming of rice, corn, and tea powered Tonkin's economy. The imports included rice, iron goods, flour, wine, opium and cotton goods. Industrialization later led to the opening of factories producing textiles and ceramics for export throughout the French Empire. French cultural influence on Tonkin was also significant as French became the primary language of education, government, trade and media and heavy Catholic missionary activity resulted in almost 10% of the population identifying as Catholic by the 1940s. Prominent buildings in Hanoi were also constructed during the period of French rule, such as the Hanoi Opera House and the Hanoi University of Technology.

World War II

French colonial administration lasted until March 9, 1945, during Japanese occupation (1941–1945). Although French administration was allowed during Japanese occupation as a puppet government, Japan briefly took full control of Vietnam in March 1945 under the Empire of Vietnam and Tonkin became the site of the Vietnamese Famine of 1945 during this period. At the end of the war, the north of Vietnam (including Tonkin) saw a sphere of influence by China while the south was briefly occupied by the British for French forces to regroup and regain control. Harry Truman at the Potsdam Conference, stated an intention to hand the region back to French rule, a sharp contrast to Franklin D. Roosevelt's strong opposition to colonialism and commitment to support the Viet Minh. However, after the Japanese withdrew from Vietnam, Ho Chi Minh proclaimed the establishment of the Democratic Republic of Vietnam in Ba Đình Square. Hanoi was later reoccupied by the French and conflict between the Viet Minh and France broke out into the First Indochina War.

End

As the French sought to establish a coherent government in Vietnam as an alternative to Ho Chi Minh, Tonkin was merged in 1948 into the Provisional Central Government of Vietnam, which was replaced the next year by the State of Vietnam, following the reunification with Cochinchina. After the French defeat at the Battle of Dien Bien Phu in Western Tonkin in 1954, the Communist state of North Vietnam was formed, consisting of Tonkin and northern Annam.
