What were the main political, economic, and social reasons for European colonialism?

Here are the major political, economic, and social motives behind European Colonialism:

• Political Motives: European powers sought to expand their empires to gain global prestige and strategic advantage. Acquiring colonies demonstrated national power and provided military bases, securing trade routes and preventing rival nations from gaining dominance.
• Economic Motives: The Industrial Revolution created a demand for raw materials like rubber, cotton, and minerals, which colonies supplied cheaply. Colonies also served as new markets for European manufactured goods and provided opportunities for investment of surplus capital.
• Social Motives: Europeans often justified colonialism through the concept of a "civilizing mission", believing they had a duty to spread Christianity and European culture. Ideas of Social Darwinism also played a role, with beliefs in European racial superiority used to rationalize domination.
