NWA世界ヘビー級王座
The NWA World Heavyweight Championship was the principal championship recognized by professional wrestling promotions affiliated with the National Wrestling Alliance (NWA). By the early 1990s, the largest NWA affiliate was World Championship Wrestling (WCW). In 1993, the relationship between WCW and the NWA board of directors began to deteriorate. In September 1993, WCW withdrew from the NWA and the NWA World Heavyweight Championship - held by WCW employee Ric Flair - was vacated.
