Iwould be super appreciative if someone could me out here! discuss the the following question: how influential were the three philosophers? why? (the three philosophers are locke, hobbes, and montesquieu)

Why did the free african americans fight for the patriot cause and explain why enslaved africans volunteered to fight for both sides

Once the constitution was approved, what more had to happen before it could go into effect?
