At the close of the
Napoleonic Wars, most of France's colonies were restored to it by
Britain, notably
Guadeloupe and
Martinique in the West Indies,
French Guiana on the coast of South America, various trading posts in
Senegal, the
Île Bourbon (
Réunion) in the Indian Ocean, and France's tiny Indian possessions. Britain finally annexed
Saint Lucia,
Tobago,
the Seychelles, and the
Île de France (
Mauritius), however.
The true beginnings of the second French colonial empire, however, were laid in 1830 with the
French invasion of Algeria, which was conquered over the next 17 years. During the
Second Empire, headed by
Napoleon III, an attempt was made to establish a colonial-type
protectorate in Mexico, but this came to little, and the French were forced to abandon the experiment after the end of the
American Civil War, when the American president,
Andrew Johnson, invoked the
Monroe Doctrine. This
French intervention in Mexico lasted from 1861 to 1867. Napoleon III also established French control over
Cochinchina (the
southernmost part of modern
Vietnam including
Saigon) in 1867 and 1874, as well as a protectorate over
Cambodia in 1863.
It was only after 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
Kwang-Chou-Wan [1] in 1900). In 1849, the
French concession in
Shanghai was established, lasting until 1946.
