The International Chess Federation (FIDE) is the world governing body of chess, headquartered in Lausanne, Switzerland. It regulates international chess competition and sets global standards for ratings, titles, and official regulations. Moreover, FIDE works with national federations to develop chess as a recognized sport worldwide.

In addition, FIDE sanctions and oversees major international events, including world championship cycles and continental championships. It administers the global rating system and norms framework that define FIDE-rated tournament requirements and title pathways. Furthermore, it supports a wide ecosystem of classical chess, rapid chess, and blitz competitions through its calendar and member federation network.

Furthermore, FIDE promotes integrity and consistent regulations through its fair play and governance frameworks. As a result, players and organizers have a unified system for titles, ratings, and event recognition across the international chess landscape, including large-scale open chess tournament festivals.
