Vassals were in turn tenants of the nobles, while the peasants were had to live on their lord's land where they had homes , had to work, and give a share of the produce to the lord, in exchange for military protection.
Republic
Anarchy was a very crazy society were there was no government. There are no laws and no constitution. Anarchy was first used in 1539. There is usually a-lot of disorder when this happens though and it is not a good form of society.
Communism
Theocracy is a system where the priests rule over the people in the name of God. Sometimes the priests would even call themselfs Gods. This was a good system but it had one big problem. If the priest wanted to he could control the people and be the dictator.
