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 to include courtly behavior and manners, influencing social interactions among the nobility. The concept became associated with romantic ideals, often depicted in literature and art, such as the tales of King Arthur and the Round Table. Today, chivalry is sometimes referenced in discussions about modern etiquette and respect.
