The International Basketball Federation, more commonly known as FIBA, FIBA World, or FIBA International, from its French name Fédération Internationale de Basket-ball, is an association of national organizations which governs international competition in basketball. Originally known as the Fédération Internationale de Basket-ball amateur (hence FIBA), in 1989 it dropped the word amateur from its official name but retained the acronym; the "BA" now represents the first two letters of basketball.FIBA defines the international rules of basketball, specifies the equipment and facilities required, regulates the transfer of athletes across countries, and controls the appointment of international referees. A total of 213 national federations are now members, organized since 1989 into five zones or "commissions": Africa, Americas, Asia, Europe, and Oceania.The FIBA Basketball World Cup is a world tournament for men's national teams held every four years. Teams compete for the Naismith Trophy, named in honor of basketball's Canadian creator James Naismith. The tournament structure is similar but not identical to that of the FIFA World Cup in football; these tournaments occurred in the same year from 1970 through 2014, but starting in 2019, the Basketball World Cup will move to the year following the FIFA World Cup. A parallel event for women's teams, the FIBA Women's Basketball World Cup, is also held quadrennially; from 1986 through 2014, it was held in the same year as the men's event but in a different country. The women's tournament will continue to be held in the same year as the FIFA World Cup.
