The governing structure for international boxing competitions is managed by multiple boxing federations and associations. The most prominent is the International Boxing Association (AIBA), which sets the rules and organizes major events, including the Olympics. Various regional bodies, such as the WBC and WBA, also govern professional boxing. Competitions follow standardized weight classes, and referees ensure adherence to rules during matches. Championships at different levels, including amateur and professional, contribute to the sport's governance and ensure fair competition globally.
