The document discusses the process of imperialism between 1875-1900, where European powers rapidly expanded their political and economic control over Africa and Asia. Key factors driving imperialism included nationalism, industrialization, a belief in the superiority of European civilization, and competition between European nations for global influence. During this period, European control of Africa increased from 10% to 90% of the continent. The Berlin Conference of 1884 essentially divided Africa among European powers without African representation, laying the groundwork for modern political issues.
