How it started
Foundation
The USWA was founded as an attempt to create a fourth national promotion, alongside Jim Crockett Promotions/WCW, AWA and the WWF (now known as WWE). The USWA was created through a merger of the WCCW (from Texas) and the CWA (based in Memphis, Tennessee). It originally promoted shows, usually headlined by Jerry Lawler, in both Tennessee and Texas.
WCCW withdraws
The Dallas promotion (formerly WCCW), which was 40 percent owned by the Von Erich family, withdrew from the USWA in September 1990 due to a revenue dispute. According to Skandor Akbar, there were lawsuits involved, most notably when Jerry Jarrett was sued by Kevin Von Erich. That promotion reverted to the World Class name, but ceased operations two months later due to lack of revenue.
Jerry Jarrett and Jerry Lawler brought the USWA back to Texas, but only on a limited basis, while promoters Joe Pedicino, Max Andrews, and Boni Blackstone were getting the new Global Wrestling Federation ready for a spring 1991 debut at the Sportatorium. Several of the former World Class and USWA Dallas wrestlers joined the new GWF, while others from the old CWA remained with the USWA.
