French Indochina (previously spelled as French Indo-China), officially known as the Indochinese Union and after 1941 as the Indochinese Federation, was a group of French dependent territories in Southeast Asia from 1887 to 1954. It was initially a federation of French colonies (1887–1949), later a confederation of French associated states (1949–1954). It comprised Cambodia, Laos (from 1899), Guangzhouwan (1898–1945), Cochinchina, and Vietnamese regions of Tonkin and Annam. It was established in 1887 and was dissolved in 1954. In 1949, Vietnam was reunited and it regained Cochinchina. Its capitals were Hanoi (1902–1945) and Saigon (1887–1902, 1945–1954).
The Second French Empire colonized Cochinchina in 1862 and established a protectorate in Cambodia in 1863. After the French Third Republic took over northern Vietnam through the Tonkin campaign, the various protectorates were consolidated into one union in 1887. Two more entities were incorporated into the union: the Laotian protectorate and the Chinese territory of Guangzhouwan. The French exploited the resources in the region during their rule, while also contributing to limited and uneven improvements of the health and education system in the region, designed to benefit the French and, to an extent, a tiny group of native elites, rather than most of the local population. Deep divides remained between the native population and the colonists, leading to sporadic rebellions by the former.
After the Fall of France during World War II, the colony was administered by the Vichy government and was under Japanese occupation until 9 March 1945, when the Japanese army overthrew the colonial regime. They established puppet states including the Empire of Vietnam. After the Japanese surrender, the communist Viet Minh movement called for an uprising, leading to the August Revolution. Ho Chi Minh, leader of the Viet Minh, subsequently proclaimed the independence of the Democratic Republic of Vietnam on 2 September 1945. 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 Vietnamese nationalists. That summer, the Viet Minh colluded with French forces to eliminate nationalists, targeted for their ardent anti-colonialism, which led to all-out the First Indochina War.
In 1945, France returned Guangzhouwan to China. To counter the Viet Minh and as part of decolonization, France, working with Vietnamese nationalists, formed the anti-communist State of Vietnam as an associated state within the French Union in 1949. This led to Cochinchina returning to Vietnam in June. Laos and Cambodia also became French associated states the same year. French efforts to retake Indochina were unsuccessful, culminating in defeat at the Battle of Điện Biên Phủ. On 22 October and 9 November 1953, Laos and Cambodia gained independence, as did Vietnam with the Geneva Accords of 21 July 1954, ending French Indochina.
French–Vietnamese contacts can be traced to 1658 when Jesuit missionaries Joseph Francis Tissanier and Pierre Jacques Albier arrived in Vietnam. Around this time, Vietnam was carrying out its Nam tiến ("Southward"), the occupation of the Mekong Delta, a territory being part of the Khmer Empire and to a lesser extent, the kingdom of Champa which they had defeated in 1471.
European involvement in Vietnam was confined to trade during the 18th century, as the remarkably successful work of the missionaries continued. In 1787, Pierre Pigneau de Behaine, a French Catholic priest, petitioned the French government and organised French military volunteers to aid Nguyễn Ánh in retaking lands his family lost to the Tây Sơn. Pigneau died in Vietnam but his troops fought on until 1802 in the French assistance to Nguyễn Ánh.
French conquest of Cochinchina
The French colonial empire was heavily involved in Vietnam in the 19th century; often French intervention was undertaken in order to protect the work of the Paris Foreign Missions Society in the country. For its part, the Nguyễn dynasty increasingly saw Catholic missionaries as a political threat; courtesans, for example, an influential faction in the dynastic system, feared for their status in a society influenced by an insistence on monogamy.
A brief period of unification under the Nguyễn dynasty ended in 1858 with French military intervention. Under the pretext of protesting the persecution and expulsion of Catholic missionaries, and following Charles de Montigny's failure to secure concessions, Napoleon III ordered Admiral Charles Rigault de Genouilly to attack Tourane (present day Da Nang).
Fourteen French gunships, 3,300 men including 300 Filipino soldiers provided by the Spanish attacked the port of causing significant damage and occupying the city. After fighting the Vietnamese for three months and finding himself unable to progress further in land, de Genouilly sought and received approval of an alternative attack on Saigon.
Sailing to southern Vietnam, de Genouilly captured the poorly defended city of Saigon on 17 February 1859. Once again, however, de Genouilly and his forces were unable to seize territory outside of the defensive perimeter of the city. De Genouilly was criticised for his actions and was replaced by Admiral Page in November 1859 with instructions to obtain a treaty protecting the Catholic faith in Vietnam while refraining from making territorial gains.
Peace negotiations proved unsuccessful and the fighting in Saigon continued. Ultimately in 1861, the French brought additional forces to bear in the Saigon campaign, advanced out of the city and began to capture cities in the Mekong Delta. On 5 June 1862, the Vietnamese conceded and signed the Treaty of Saigon whereby they agreed to legalize the free practice of the Catholic religion; to open trade in the Mekong Delta and at three ports at the mouth of the Red River in northern Vietnam; to cede the provinces of Biên Hòa, Gia Định and Định Tường along with the islands of Poulo Condore to France; and to pay reparations equivalent to one million dollars.
In 1864 the aforementioned three provinces ceded to France were formally constituted as the French colony of Cochinchina. Then in 1867, French Admiral Pierre de la Grandière forced the Vietnamese to surrender three additional provinces, Châu Đốc, Hà Tiên and Vĩnh Long. With these three additions all of southern Vietnam and the Mekong Delta fell under French control.
Establishment and early administration
In 1863, the Cambodian king Norodom had requested the establishment of a French protectorate over his country. In 1867, Siam (modern Thailand) renounced suzerainty over Cambodia and officially recognised the 1863 French protectorate on Cambodia, in exchange for the control of Battambang and Siem Reap provinces which officially became part of Thailand. (These provinces would be ceded back to Cambodia by a border treaty between France and Siam in 1906).
France obtained control over northern Vietnam following its victory over China in the Sino-French War (1884–85). French Indochina was formed on 17 October 1887 from Annam, Tonkin, Cochinchina (which together form modern Vietnam) and the Kingdom of Cambodia; Laos was added after the Franco-Siamese crisis of 1893.
The federation lasted until 21 July 1954. In the four protectorates, the French formally left the local rulers in power, who were the emperors of Vietnam, kings of Cambodia, and kings of Luang Prabang, but in fact gathered all powers in their hands, the local rulers acting only as figureheads.
Japanese women called Karayuki-san migrated or were trafficked to cities like Hanoi, Haiphong and Saigon in colonial French Indochina in the late 19th century to work as prostitutes and provide sexual services to French soldiers who were occupying Vietnam. Since the French viewed Japanese women as clean, they were highly popular. Images of the Japanese prostitutes in Vietnam were put on French postcards by French photographers. The Japanese government tried to hide the existences of these Japanese prostitutes who went abroad and did not mention them in books on history.
