Explanation:

The term New Imperialism (also Neoimperialism) refers to the policy and ideology of colonial expansion and imperialism adopted by the European powers and later by the United States and Japan from the late nineteenth century to the early twentieth century, approximately since the Franco-War. Prussian (1870) until the beginning of the First World War (1914). The qualifier "new" is to contrast it with the first wave of European colonization from the fifteenth to the nineteenth centuries and with imperialism in general. It is characterized by an unprecedented persecution of what has been called "the empire for the empire itself", an aggressive competition for the acquisition of overseas territories accompanied by the emergence in colonizing countries of doctrines of racial superiority that denied the ability of the peoples subjugated to govern themselves.

As around 1880, most of Africa was still not occupied by the Western powers, that continent became the main objective of the "new" imperialist expansion, giving rise to the so-called "African Distribution". This expansion also took place in other areas, notably in Southeast Asia and the maritime regions of East Asia, where the United States and Japan joined the European powers in the territorial distribution.

During the 1940s, 1950s and 1960s, a wave of independentist uprisings put an end to the European colonial empires that still survived.
