What was imperialism

Imperialism is a policy or ideology of extending a country's rule over foreign nations, often by military force or by gaining political and economic control of other areas.

Imperialism was both normal and common throughout recorded history, the earliest examples dating from the mid-third millennium BC. In recent times, it has been considered morally reprehensible and prohibited by international law. Therefore, the term is used in international propaganda to denounce an opponent's foreign policy.
