The Code Duello is a set of rules that governed the conduct of duels, primarily in the 18th and 19th centuries. It provided guidelines on how to challenge someone to a duel, the choice of weapons, and the procedures to follow during the duel. The code aimed to ensure that duels were conducted fairly and honorably, reflecting the values of honor and respect among gentlemen. These rules were often documented in various forms, with notable examples like the one created by the Irish politician John Lyde Wilson in 1777. The Code Duello played a significant role in shaping social norms around honor and conflict resolution during its time, influencing how disputes were settled among the elite.
