Imperialists looked to Africa to supply cheap labor for their colonies.

Explanation:

European colonies were established to generate profit for the crowns of their countries, during imperialism. In order to increase profit from colonial exploitation, European empires sought a cheap way to obtain large-scale labor. Firstly, they tried to dominate the natives and make them work forcibly in the economic productions of the colonies, however this practice was severely prohibited by the Catholic Church, forcing the imperialists to look for other forms of labor. For this reason, Europeans began an enslavement of Africans, which proved to be cheap and legalized, giving many profits to the empires.
