Usage of Colonialism and Imperialism

In contexts dealing with the domination of a people or area by a foreign power, colonialism and imperialism are often used together with no real distinction in meaning. Used separately, however, each of these words can take on a slightly different emphasis. Colonialism comes from colony, and tends to be applied in contexts addressing the effects that colonialism has on the lives of those living in colonies. Imperialism is closely related to empire and therefore tends to place more emphasis on the ruling power and its intent to expand its dominion, as well as on the expanded empire itself, with its distinct parts subsumed under the banner of the dominating force.
