Colonialism

Colonialism is the establishment, exploitation, maintenance, acquisition and expansion of colonies in one territory by people from another territory. It is a process whereby the metropole claims sovereignty over the colony, and the social structure, government, and economics of the colony are changed by colonizers from the metropole. Colonialism is a set of unequal relationships between the metropole and the colony and between the colonists and the indigenous population.

The European colonial period was the era from the 1500s to, arguably, the 1900s when several European powers (particularly, but not exclusively, Spain, Portugal, Britain, the Netherlands and France) established colonies in Asia, Africa, and the Americas. At first the countries followed mercantilist policies designed to strengthen the home economy at the expense of rivals, so the colonies were usually allowed to trade only with the mother country. By the mid-19th century, however, the powerful British Empire gave up mercantilism and trade restrictions and introduced the principle of free trade, with few restrictions or tariffs.
