This document discusses the roots of Western imperialism between 1870-1914. It provides three main reasons for European imperialism: political, economic, and cultural. Politically, European leaders sought colonies as sources of troops and to increase national prestige. Economically, they wanted colonies for raw materials, new markets, and land for a growing population. Culturally, Europeans viewed non-Western peoples as primitive and aimed to spread Christianity and their cultural values. The document outlines different types of colonial control and provides examples of how imperialism impacted specific regions of Africa and Asia.
