A knight is a mounted soldier from the medieval period, often associated with chivalry and noble service. Knights were typically granted land or titles in exchange for their military service to a lord or king. They wore armor and fought on horseback, playing a crucial role in battles and tournaments. The concept of knighthood is closely linked to the feudal system, where loyalty and honor were paramount. Knights followed a code of conduct known as chivalry, which emphasized bravery, courtesy, and protection of the weak. This idealized image of knights has influenced literature and popular culture throughout history.
