Analysis of information sources in references of the Wikipedia article "New Imperialism" in English language version.
[...] the concept of the 'new imperialism' espoused by such diverse writers as John A. Hobson, V. I. Lenin, Leonard Woolf, Parker T, Moon, Robert L. Schuyler, and William L. Langer. Those students of imperialism, whatever their purpose in writing, all saw a fundamental difference between the imperialist impulses of the mid- and late-Victorian eras. Langer perhaps best summarized the importance of making the distinction of late-nineteenth-century imperialism when he wrote in 1935: '[...] this period will stand out as the crucial epoch during which the nations of the western world extended their political, economic and cultural influence over Africa and over large parts of Asia ... in the larger sense the story is more than the story of rivalry between European imperialisms; it is the story of European aggression and advance in the non-European parts of the world.'
Commentators have identified three broad waves of European colonial and imperial expansion, connected with specific territories. The first targeted the Americas, North and South, as well as the Caribbean. The second focused on Asia, while the third wave extended European control into Africa.
