But villeins and serfs had rights as well. They could cultivate grain and vegetables for sale, and the lord had duty to protect them and provide them land to cultivate. If they got wealthy enough, they could buy their freedom from the lord. They also did not need to serve in levy (that is: army mustered up by conscription) and they did not need to pay state taxes. They usually paid 10% of their income to the Church and 10% to the feudal lord, which was called a tithe.
