A chess federation is an organization that governs and promotes the game of chess within a specific region or country. These federations are responsible for organizing tournaments, setting rules, and supporting players at all levels, from beginners to professionals. They also work to develop chess programs in schools and communities to encourage participation in the game. The most recognized international chess federation is the Fédération Internationale des Échecs (FIDE), which oversees global competitions and establishes official chess ratings. National federations, such as the United States Chess Federation (USCF), operate under FIDE's guidelines and help coordinate local events and player rankings.
