Europe's colonial expansion, 1820-1939

European countries began exploring and seeking to dominate the rest of the world during the 15th and 16th centuries, thanks to their ability to control sea routes and to the exploration of the American continent. In the 19th century, energized by the industrial revolution and under pressure from a rapidly growing population, Europe launched a new period of colonial expansion, inspired by the discovery of new markets, new areas for the settlement of Europe’s poor migrants, and the desire to "civilize the barbarian nations ".
