Terry Jones' Medieval LivesTV Show

Terry begins by explaining that the common perception of the knight may in fact be historically inaccurate. William the Bastard (later known as William the Conqueror) conquered England in 1066. His followers, called 'cnihts' gained land and property in exchange for military service. Any group of men chosen for their ability to beat things and not much else tends to have discipline problems, though, so a code of conduct was necessary to set in place. This became known as 'chivalry'.
