The original Japanese-based Universal Wrestling Federation (UWF) was a Japanese professional wrestling promotion from 1984 to 1986, formed by wrestlers who had left New Japan Pro Wrestling. It was a pioneer in the shoot-style of pro-wrestling, which emphasized realistic moves. It was revived as the Newborn UWF in 1988. Newborn UWF lasted until 1990. It was revived again in 1991 as Union of Wrestling Forces International (UWF International or UWFi), which in turn lasted until 1996.
