Mercantilism played a major role in the exploration and discovery by European powers in the 15th and 16th centuries. Define mercantilism and explain how England, France, and Spain used this concept as an excuse for expansion. Also, explain how African slavery became vital to the New World.

I started the essay already and defined mercantilism. I just need someone to explain the 2nd part of the prompt and basically finish off my essay because I will not have time to complete it today.
