With the Norman Conquest, England entered the medieval period, a time of innovation in the midst of war.
Medieval literature is best understood in the context of three powerful influences on medieval society: feudalism, the church, and a code of conduct called chivalry.
Medieval works, such as The Canterbury Tales and the Arthurian romances, drew from many sources, historical and contemporary, while reflecting the society and ideals of their time.
