Why Feudalism Formed

Nobles weren't able to get protection from the king. Nobles had to defend their land and property so they hired knights. Nobles became bery powerful; sometimes even more powerful then the king. Instead of giving the knights money, the nobles gave the knights protection and land. A vassal was a knight who promised to support a lord in exchange for land. Feudalism was the system of promises that governed this relationship between the lords and the knights.

This the social structure for feudalism. At the top was the kings and queens, then it was the nobles, then the knights and at the bottom were the peasants.
