What was feudalism?What were the 5 different roles of Feudalism?

Feudalism, also known as the feudal system, was a combination of the legal, economic, military, and cultural customs that flourished in Medieval Europe between the 9th and 15th centuries.

I'm not sure what you meant about the roles but if you mean the social pyramid then I can help with that

African americans at the time just came out of slavery and needed money to provide for there families. so they joined for the money mainly.
