What did the knights do to show loyalty?

Knights demonstrated loyalty primarily through their adherence to the code of chivalry, which emphasized bravery, honor, and respect for their lord and fellow knights. They pledged allegiance to their lord, often through a formal ceremony, and were expected to defend their lord's territory and interests in battle. Additionally, knights participated in tournaments and other events to showcase their skills and loyalty, further solidifying their commitment to their feudal obligations.
