A knight is a person granted an honorary title of knighthood by a monarch, bishop or other political leader for service to the monarch or a Christian Church, especially in a military capacity. Historically, in Europe, knighthood was conferred upon mounted warriors. During the High Middle Ages, knighthood was considered a class of lower nobility. By the Late Middle Ages, the rank had become associated with the ideals of chivalry, a code of conduct for the perfect courtly Christian warrior. Often, a knight was a vassal who served as an elite fighter, a bodyguard or a mercenary for a lord, with payment in the form of land holdings. The lords trusted the knights, who were skilled in battle on horseback.
