Colonialism is the extension of a nation's sovereignty over territory and people outside its own boundaries, often to facilitate economic domination over their resources, labor, and markets. The term also refers to a set of beliefs used to legitimize or promote this system, especially the belief that the mores of the colonizer are superior to those of the colonized.
Cons
Colonialism involves the rule or taking of territory of one people by another and
without their consent, it is a highly emotive subject. Debate about the perceived positive and negative aspects of colonialism has occurred for centuries, amongst both colonizer and colonized.
