Answer:Under feudalism, which was based on an agricultural economy, distinct social classes were dependent on one another through a complex system of pledging loyalty in exchange for goods and services. At the top were kings, who owned the land. Beneath them were lords (noblemen) and clergymen (church officials), who were granted tracts of land called fiefs by the king. Below the lords were vassals (knights), who held smaller amounts of land awarded to them by lords. At the bottom were serfs (peasants), who farmed the fiefs but were not given land of their own. Land occupied by churches, monasteries (houses for men called monks, who dedicated themselves to the religious life), and other religious establishments of the Roman Catholic Church were also considered fiefs.
