Due to some political problems between 1947 and 1948, the league’s first season was in 1948, and has been held yearly since. Since the 1968 season the league has used the Apertura and Clausura system, although they have only crowned a champion for each tournament since the 2002 season. In 1989, the season was cancelled mid-way through because of the assassination of a referee.
