The first Women's Rugby World Cup was held in 1991 and won by the United States. The 1991 and 1994 competitions were not officially sanctioned by World Rugby, then known as the International Rugby Football Board, at the time - they later received retrospective endorsement in 2009 when the governing body, which by that time had changed its name to the International Rugby Board, included the 1991 and 1994 champions in its list of previous winners. It was not until the 1998 tournament held in the Netherlands that the tournament received official IRB backing, and the IRB retroactively recognised the preceding tournaments. The most successful team, with five titles, is New Zealand.
