Which event in 1884–1885 set rules for European claims over territory in Africa?

The Berlin Conference set rules for European claims over territory in Africa in 1884–1885. Hosted by German Chancellor Otto von Bismarck in Berlin, the meeting involved European powers and the United States, but no African government was represented.

The conference established principles concerning trade, navigation, and the formal recognition of territorial claims. Its General Act required effective occupation for European powers seeking to validate claims, helping accelerate the period known as the Scramble for Africa. The meeting did not draw every modern African border by itself, but it created a diplomatic framework that encouraged rapid colonial expansion.

The conference lasted from November 1884 to February 1885. Its consequences were profound: by the early twentieth century, most of Africa had been colonized by European powers, with Ethiopia and Liberia remaining notable exceptions to direct European rule. The event is therefore associated with, but not identical to, the broader Scramble for Africa.
