The World Cup is currently organised by the International Cricket Council (ICC). Until 2005, when the two organisations merged, it was administered by a separate body, the International Women's Cricket Council (IWCC). The first World Cup was held in England in 1973, two years before the inaugural men's tournament. The event's early years were marked by funding difficulties, which meant several teams had to decline invitations to compete and caused gaps of up to six years between tournaments. However, since 2005 World Cups have been hosted at regular four-year intervals.
