What economic system did colonialism strengthen as trade increased between European empires?

Imperialism.

Explanation:

Imperialism represents the highest stages of colonial politics. It is a system that essentially contains economic and military doctrine. The goal of imperialism is always profit, and the imperialists do not choose the means to realize their plans. Imperialism began with the discovery of America, that is, in the years after the discovery. Since then, European countries have been competing for the colonization of the world, and such a trend lasted until the middle of the twentieth century.
