Age of Imperialism. The Age of Imperialism, a time period beginning around 1760, saw European industrializing nations, engaging in the process of colonizing, influencing, and annexing other parts of the world. 19th century episodes included the "Scramble for Africa."

When did imperialism start and why?

From the mid-1850s to the beginning of World War I, many Western nations were expanding into Asia. The "Age of Imperialism" was fueled by the Industrial Revolution in Europe and the United States, and it profoundly influenced nation building efforts in Japan and China.

Who started imperialism?

The term imperialism was originally introduced into English in its present sense in the late 1870s by opponents of the allegedly aggressive and ostentatious imperial policies of British Prime Minister Benjamin Disraeli. Supporters of "imperialism" such as Joseph Chamberlain quickly appropriated the concept.
