What is the central idea of colonialism in the united states

The central idea of colonialism in the United States was to establish a large trade based on overpopulation of the nation, as many people in England sought the New World for religious freedom.

Explanation:

Colonialism is a practice in which a territory exercises political, cultural or religious dominion over a particular people. Control is exercised through a foreign military political power or force that wishes to exploit, maintain or expand its territory.  Most of the time, this practice happens without the consent of its native inhabitants, who with exploitation lose part of their assets (land, natural resources, housing) or possible political rights they might have.

Colonialism in the United States was made by England. Englishmen from various social, political and religious groups came to inhabit the new world for several different reasons. The reason that led England to try to colonize North America was not the ambition to become a Colonial Empire, but the interest in the nation's trade and overpopulation, as many people sought the New World for religious freedom.

i think it's either 'to expose the corruption of the communists in russia', or 'to criticize animal brutality by communists in russia.'
