The French colonial empire (French: Empire colonial français) consisted of the overseas colonies, protectorates, and mandate territories that came under French rule from the 16th century onward. A distinction is generally made between the "first French colonial empire", that existed until 1814, by which time most of it had been lost or sold, and the "second French colonial empire", which began with the conquest of Algiers in 1830. On the eve of World War I, France's colonial empire was the second-largest in the world after the British Empire.
France began to establish colonies in the Americas, the Caribbean, and India in the 16th century but lost most of its possessions after its defeat in the Seven Years' War.
