The document summarizes the second wave of European colonial conquests from 1750-1900. It involved new European powers like Germany, Italy, Belgium, the US, and Japan expanding their colonies to South and Southeast Asia, Africa, and the Pacific Islands. The colonies were divided into "white colonies" like Canada, Australia and New Zealand that were settlements for Europeans, and "non-white colonies" in Asia and Africa that were ruled indirectly through local elites but controlled by European governments from abroad. By the late 1800s, European powers had partitioned most of Africa at the Berlin Conference and established control over 90% of the land by 1914.
