French Indochina (French: Indochine française; Vietnamese: Đông Dương thuộc Pháp, frequently abbreviated to Đông Pháp) is part of the French Union in southeast Asia. It borders in the north with China, British Burma to the northwest, Thailand to the west, to the southwest the Gulf of Thailand, and the South China Sea, referred to as East Sea (Vietnamese: Biển Đông), to the east.

French Indochina is a federation of three Vietnamese regions, Tonkin (North), Annam (Central), and Cochinchina (South), as well as Cambodia, formed in 1887. Laos was added in 1893 and Kwang-Chou-Wan in 1900. The capital was moved from Saigon (in Cochinchina) to Hanoi (Tonkin) in 1902.

Government of Indochina

Initially Indochina was under the direction of a Governor General, appointed by the French Government. Under his direction were the French colony of Cochinchina and the protectorates of Tonkin, Annam, Laos and Cambodia. Each one under the direction of a Resident-Superior or Governor named by the Governor General.

After the Yen Bai mutiny of 1930, the central government pushed for a reform of the colonial governance and a limited autonomy of Indochina. Part of the revolt came from the parallel structure in the administration. Native and French, the last one supervising the former. This created a tension between colonial and local interest, such has the lack of knowledge of many French administrators of Vietnamese language. Also the necessity considering that the zones of former Vietnam, during the mutiny, had given a large local support to it.

The 1932 reform of Indochina established the Governor General named for a term of 5 years, renewal for another term. An elected Territorial Assembly serves in an advisory function and approves or modifies the budget. The colony of Cochinchina and protectorates of Tonkin, Annam where reformed. Each one is under the direction a Territorial Governor, named by the Governor General. They are assisted by an elected Territorial Council. All the Assemblies are elected by two separate electorates: Natives and French for a term of 5 years.

The protectorates of Cambodia and Laos maintain their autonomy under the direction of their monarchs, assisted by a Resident-Superior and Provincial Residents, all named by the Governor General. The protectorates however have to enact their own constitutions that must limit the executive powers of the monarchs. Vietnamese is made the co-official language in the administration, local government, justice courts and education in all Indochina. Khmer and Lao are only co-official in Cambodia and Laos.

The Territory of Kwang-Chou-Wan (1898-1936) was under the supervision of the Territorial Governor of Tonkin, who named its Administrator. Chinese and French where the co-official languages.

By means of the reform, the public administration is wrap up in one common civil service under the direction of the Governor General, whose enrollment is made by means of examinations and merit.

With the end of the protectorates of Tonkin and Annam in 1932, the Emperor of Vietnam (Nguyễn Dynasty) had only a symbolic role. Under reserve orders, the Governor General was instructed to keep a regal expenditure from public funds for the lavish lifestyle of the Nguyễn Dynasty. This as one of the means to keep them out of state functions. The monarchs of Cambodia and Lao where rewarded for their loyalty during the Yen Bai mutiny (1930) in keeping their internal autonomy.


Vietnamese Nationalism, a constant source of unrest and surveillance by French authorities resurged after the Versailles Treaty. A delegation traveled to France and at the French at the Versailles Peace Conference presented a list of demands to the colonial authorities. These included representation in the French parliament, freedom of speech, and release of political prisoners. These demands where ignored and several Nationalist and Communist organizations sprang up in Vietnam.

The most enduring and organized parties that surged were the Viet Nam Quoc Dan Dang (VNQDD) and the Indochinese Communist Party (PCI, Vietnamese: Đảng Cộng sản Đông Dương) which was transformed from the old Vietnamese Communist Party (Việt Nam Cộng sản Đảng).

Vietnamese Nationalism after the Yen Bai mutiny of 1930, become more modeled and a mirror of power struggles in China. The Chinese KMT support the VNQDD, and Chinese Communist the PCI. Both VNQDD and PCI decided to create a political base within the peasantry. This was to prove instrumental in the later success of the VNQDD. A more collaborationist line followed parties like the Vietnamese Constitutional Association (ACV).

The French also organized their own political parties following the divisions and affiliation of the ones in the French Metropolis.

Different was the political development in Cambodia and Laos. The fear of domination by the Vietnamese encouraged the formation of nationalist parties that became the political vehicles of the established rulers. These parties were pro-loyalist, pro-French and reformist in their outlook. However some follow more independentist and nationalist stance that also merged with local Buddhism and/or millenarian visions.

Economy of Indochina

The currency was French Indochinese piastre (1885-1925) issued by the Banque de l'Indochine. After the monetary reform of 1925, the currency is the Franc d'outre-mer (FOM, 1925) issued by the caisse centrale de la France d'outre-mer (CCFOM). Although devoid of its main function, the Banque de l'Indochine expanded its operations and office in the rest of Indochina, China and Asia. Becoming one of the principal investment banks and one main financial institutions for foreign trade in this area of the World. Economic development and promotion of trade is helped by the Agence économique de l'Indochine (AEI). A public concern that provides information, propaganda and credit.

The main agricultural production of Indochina is rice, rubber plantations, indigo, tea and coffee. Also important is mining, cigarette manufacturing, breweries and distilleries. The funding and promotion of the AEI has helped in establishing iron and steel works in Hanoi-Haiphong and Saigon. Fishing and related industries are also important in the South China Sea and in the Mekong river and delta.

In 1935 it was started the construction of Transindochinese (Transindochinois) railroad, initially running from Saigon to Hanoi, later extended to Phnom Penh.
