Colonialism is the maintenance of political, social, economic, and cultural dominance over a people by a foreign power for an extended period of time. This often involves the establishment of settlements and the exploitation of resources in the colonised territory for the benefit of the colonizing power. Colonialism has had a profound and lasting impact on the political, economic, and social structures of many regions around the world, leading to significant cultural changes and often resulting in inequalities and conflicts that persist even after the end of colonial rule. The motivations for colonialism have varied throughout history, including economic gain, political power, strategic advantage, and the spread of religious or cultural beliefs. The study of colonialism examines its historical roots, its various forms and impacts, and its enduring legacies in the contemporary world.
