Colonialism is the policy of a foreign politics seeking to extend or retain its authority over other people or territories, generally with the aim of opening trade opportunities. The colonizing country seeks to benefit from the colonized country or land mass. In the process, colonizers imposed their religion, economics, and medicinal practices on the natives. Some argue this was a positive move toward modernization, while other scholars refute this theory as being biased and Eurocentric, noting that modernization is a concept introduced by Europeans. Colonialism is largely regarded as a relationship of domination of an indigenous majority by a minority of foreign invaders where the latter rule in pursuit of its interests.
