What is colonialism?

The history of colonialism is one of brutal subjugation of indigenous peoples.

Explanation:

Colonialism is defined as control by one power over a dependent area or people. It occurs when one nation subjugates another, conquering its population and exploiting it, often while forcing its own language and cultural values upon its people.
