A code duello is a set of rules for a one-on-one combat, or duel. Codes duello regulate dueling and thus help prevent vendettas between families and other social factions. They ensure that non-violent means of reaching agreement are exhausted and that harm is reduced, both by limiting the terms of engagement and by providing medical care. Finally, they ensure that the proceedings have a number of witnesses. The witnesses could assure grieving members of factions of the fairness of the duel, and could help provide testimony if legal authorities become involved.
