Medieval knights were heavily armored soldiers who served as mounted warriors during the Middle Ages. They were often part of the noble class and followed a code of conduct known as chivalry, which emphasized bravery, honor, and respect for women and the weak. Knights were typically trained from a young age, starting as pages and then becoming squires before earning their title. Knights played a crucial role in battles and were often granted land in exchange for their military service. They fought on horseback, wielding weapons like swords and lances. Their presence was significant in the feudal system, where loyalty and service were essential for maintaining power and land.
