The area that was colonized under new imperialism was Africa.

The term New Imperialism 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 19th century to the early 20th century, approximately since the Franco-Prussian War (1871) until the beginning of the First World War (1914).

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 "Scramble for Africa".
