Imperialism vs. Colonialism
Imperialism and colonialism are closely related, but they are not always interchangeable.

Colonialism generally refers more specifically to establishing control over a territory, often involving settlement and formal colonial administration.
Example:
Imperialism can involve economic influence, while colonialism traditionally involves direct territorial control.

Imperialism can involve expansion, but it also includes broader forms of political, economic, and cultural domination.
For example:
