During the Middle Ages, feudalism was the dominant social system. A vassal receives land from noble in return for the vassal to pledge to send knights to protect the Noble Count (Document 2). The feudal obligations were that the vassal must serve loyalty, service and ransoms to his lord. And in return, the lord gives land and protection. The feudal impose had a limited period of service that was specifically designed to guarantee that the agricultural land was not rejected for a longer period of time, therefore allowing this system to be a system of society (Document 4). This system runs by land being powerful, therefore people make a feudal contract to receive land in exchange for something.
