I have followed pro wrestling since I was 9 years old in 1997. I mainly follow WWE but am pretty attuned to the overall wrestling scene in general. The lack of Black world champions is very noticeable, as pro wrestling really hasn't followed the demographics change which is prevalent in so many other sports. Ron Simmons (former Florida State Defensive Tackle and College Football Hall of Fame member) became the first Black world champion of a major wrestling promotion when he won the WCW title in 1992, while the company was run by Bill Watts who was fired after comments became public in support of businesses being able to segregate (WCW was owned by Ted Turner and operated out of Atlanta and Hank Aaron had major influence in the Turner company and is believed to have led the push to have Watts fired). Ever since, the only Black world champions I can think of have been The Rock (half Polynesian) and Bobby Lashley (who held the third biggest title in WWE at the time). Ring Of Honor which is owned by conservative Sinclair Broadcasting has a Black world champion named Jay Lethal. Other than that, the biggest non white stars in wrestling tend to either be Japanese, Polynesian, or Latino. The current WWE Champion is Roman Reigns (Joe Ano'ai, former Georgia Tech Defensive Tackle), a full blooded Polynesian, who just won the title from Brock Lesnar. As for Latinos, Pedro Morales who is Puerto Rican held the old WWWF title for two years in the early 70's. Eddie Guerrero, Alberto Del Rio, and Rey Mysterio have also held world titles in WWE, but none of them held the biggest title. Dave Bautista who is half Greek and Filipino was also champion on numerous occasions. The biggest changes in WWE in recent years have all been gender related, as there is a huge push to promote women's wrestling at the same level as men's wrestling due to the influence of Vince McMahon's daughter Stephanie and her husband Triple H (Paul Levesque). Even the top females are mostly Caucasian, and the current face of the women's division is Ronda Rousey, the former UFC women's champion, along with Charlotte Flair, the daughter of Ric Flair.
I was thinking about this site in relation to the recent Summerslam show, which took place this past Sunday. Out of 36 people who wrestled on the show, 27 were White and only 4 were Black. The aforementioned Roman Reigns won the top title during this show and the challenger for the second biggest men's title is also Polynesian. The two women's title matches featured all White performers.
It is very interesting that the demographics of WWE remain overwhelmingly Caucasian, and that the biggest changes in professional wrestling are actually related to gender rather than race.
