Freedom
Feudalism was a way of structuring society that was dominant in Europe between the 9th and the 15th centuries.
In a feudal system, lords owned the land, which was then granted to vassals. The vassal promised to fight for the lord at his command, while the lord promised protection and a piece of land in exchange for this service.
Usually, the piece of land granted to the vassal came with serfs, which were bought, sold or traded as they were in a type of debt bondage. Serfs (peasants) could not leave the land they were bound to and had no rights over their bodies. In exchange for free labor, they were entitled protection, justice and enough land for their own subsistence.
