Imperialism and World Economy

Imperialism is an action that involves a country (usually an empire or a kingdom) extending its power by the acquisition of territories. It may also include the exploitation of these territories, an action that is linked to colonialism. Colonialism is generally regarded as an expression of imperialism.

It is different from New Imperialism, as the term imperialism is usually applied to the colonization of the Americas between the 15th and 19th centuries, as opposed to the expansion of Western Powers (and Japan) during the late 19th and early 20th centuries. However, both are examples of imperialism.
