Imperialism

Oxford Dictionary defined Imperialism as a policy of extending a country’s power and influence through 

colonization, use of military force.

Colonialism vs. imperialism

Imperialism is different from colonialism. Edward Said,  Palestinian literary theorist,  said imperialism involves “the practice, the theory and the attitudes of a dominating metropolitan centre ruling a distant territory’. He says colonialism is the “implanting of settlements on a distant territory”. Robert Young, post-colonial theorist, supports this thinking as he puts forward that imperialism operates from the center, it is a state policy, and is developed for ideological as well as financial reasons whereas colonialism is nothing more than development for settlement or commercial intentions

They're the same in terms of expanding outside a country's borders. Though both the words underline suppression of the other, Colonialism is where one nation assumes control over the other and Imperialism refers to political or economic control, either formally or informally. In simple words, colonialism can be thought to be a practice and imperialism as the idea driving the practice.

Colonialism is a term where a country conquers and rules over other regions. It means exploiting the resources of the conquered country for the benefit of the conqueror. Imperialism means creating an empire, expanding into the neighbouring regions and expanding its dominance far.
