Chivalry originated in the medieval period as a code of conduct for knights. It emphasized virtues such as bravery, honor, and respect for women. Knights were expected to protect the weak and uphold justice, reflecting the ideals of feudal society. Over time, chivalry evolved beyond the battlefield to influence social behavior. It became associated with courtly manners and the romanticized treatment of women, often seen in literature and art. While the strict code of chivalry has faded, its principles still resonate in modern discussions about ethics and gentlemanly behavior.
