The Age of Imperialism is typically considered to have occurred from the late 19th century to the early 20th century, roughly from the 1870s to the outbreak of World War I in 1914. This period was characterized by the expansion of European powers and the United States into Africa, Asia, and the Pacific, driven by economic interests, national pride, and a belief in racial superiority. Major events during this time included the Scramble for Africa and the establishment of colonies around the world.
