context_page_description: This Timeline of European imperialism covers episodes of imperialism by western nations since 1400 but does not take into account imperialism by other nations such as the Inca, the Chinese Empire or Japanese Imperialism, to give only a few of many examples. As such, readers may wish to treat it with some caution if using it as a resource to understand the complete phenomena of imperialism and colonialism.
