involves political and economic control over a dependent territory usually for its natural resources.

The correct answer is Imperialism

Imperialism is the practice by which powerful nations seek to expand and maintain control or influence over poorer peoples or nations.

Sometimes imperialism is associated only with the economic expansion of capitalist countries; other times it is used to designate European expansion after 1870. Although Imperialism means the same as Colonialism and the two terms are used in the same way, we must distinguish between one and the other.

Colonialism usually implies political control, involving annexation of territory and loss of sovereignty.

Imperialism refers, in general, to the control and influence that is exercised both formally and informally, directly or indirectly, politically or economically.
