Outline of Vietnam
Vietnam was under Chinese control for a thousand years before becoming a nation-state in the 10th century. Successive dynasties flourished along with geographic and political expansion deeper into Southeast Asia, until it was colonized by the French in the mid-19th century. Efforts to resist the French eventually led to their expulsion from the country in the mid-20th century, leaving a nation divided politically into two countries. Bitter fighting between the two sides continued during the Vietnam War, ending with a communist victory in 1975.
French colonial empire
It was only after its defeat in the Franco-Prussian War of 1870–1871 and the founding of the Third Republic (1871–1940) that most of France's later colonial possessions were acquired. From their base in Cochinchina, the French took over Tonkin (in modern northern Vietnam) and Annam (in modern central Vietnam) in 1884–1885. These, together with Cambodia and Cochinchina, formed French Indochina in 1887 (to which Laos was added in 1893 and Guangzhouwan in 1900). In 1849, the French concession in Shanghai was established, lasting until 1946. The French also had concessions in Guangzhou and Hankou (now part of Wuhan).
