31 de ene. de 2023 · New Imperialism, period of intensified imperialistic expansion from the latter half of the 19th century until the outbreak of World War I in 1914. The renewed push to expand territorial control included not only the earlier colonial powers of western Europe but also newcomers such as Germany, Italy, Japan, Russia, and the United States.
This new vigour in the pursuit of colonies is reflected in the fact that the rate of new territorial acquisitions of the new imperialism was almost three times that of the earlier period. Thus, the increase in new territories claimed in the first 75 years of the 19th century averaged about 83,000 square miles (215,000 square kilometres) a year.
Imperialism is a term used to describe the ideas, beliefs, and actions that one group uses to justify and hold control over the others. Colonialism is the experience of the other groups who are being ruled. But again, these last two terms are, in practice, sometimes used interchangeably. Now, empires go back thousands of years in world history!
Under the leadership of Japan and the totalitarian states—Italy under the Fascist Party, Nazi Germany, and the Soviet Union —a new period of imperialism was inaugurated in the 1930s and ’40s. Get a Britannica Premium subscription and gain access to exclusive content. Subscribe Now
