The National Wrestling Alliance (NWA) is a professional wrestling organization founded in 1948. It is one of the oldest and most influential wrestling organizations in the world, and has been a major player in the industry for many decades. The NWA has a rich history, with many of the biggest names in professional wrestling, including Lou Thesz, Harley Race, and Ric Flair, having competed in the promotion. The NWA was also a driving force in the territorial system of professional wrestling, where different promotions operated in different regions across the United States. In the 1990s and 2000s, the NWA went through a period of decline, but has since undergone a resurgence in recent years, with a focus on promoting traditional, hard-hitting professional wrestling. Today, the NWA is a collective of independent wrestling promotions that share the NWA name and championship titles, and strive to preserve the legacy of the National Wrestling Alliance.
