Campomanes is best remembered as the President of FIDE, to which post he was elected in 1982, and held until 1995, through several controversies, most notably the abandonment of the 1984–85 match between Karpov and Garry Kasparov without result, after 48 games, and the break-away from FIDE of the Professional Chess Association in 1993. The cancellation threw the international chess calendar into disarray for the next several years, since a series of matches had to be held to resolve the matter, and these affected other qualifying events.
