In the second half of the nineteenth century Vietnam, Laos, and Cambodia all fell under French rule, and the Nguyen Dynasty’s emperors became no more than puppets of the French. The French conquest began under Napoleon III, whose forces captured Saigon in 1859. By 1867 the French had taken control of the whole of Cochin China, roughly the southern third of Vietnam. They also secured a protectorate over Cambodia. The French conquest of Vietnam was completed under the Third Republic, after the fall of Napoleon III’s Second Empire during the Franco-German War of 1870-1871. In 1883 France used military force to get Emperor Tu Duc to accept a protectorate over the rest of Vietnam. In 1893 the French rounded off their empire in Indochina by establishing a protectorate over Laos. Although Cochin China was technically a colony and the rest of Vietnam, Cambodia, and Laos were protectorates, the French endeavored to establish a fairly unified administrative system throughout the area they ruled.
