Formation of ITF

From the roots of Davis Cup and the need to establish an international tennis federation, in 1913, twelve National Tennis Associations agreed at a Paris Conference to form the International Lawn Tennis Federation, which was renamed in 1977 as the current International Tennis Federation (ITF). The comprehensive International Lawn Tennis Federation rules promulgated in 1924 have remained remarkably stable in the ensuing eighty years, the one major change being the addition of the tie-breaker system designed by James Van Alen.
