The WWE World Championship was created in 1963, and Buddy Rogers became the first world champion on April 29. It may have been created because of things that happened in the National Wrestling Alliance (NWA) which is a wrestling company (or promotion) that had many "territories" in North America and some around the world. In the 1950s, Capitol Wrestling Corporation (CWC) was an NWA territory, and in 1963, people in CWC had a lot of control over the rest of the NWA. During this time, Buddy Rogers held the NWA World Heavyweight Championship, the world title of the NWA, until Lou Thesz defeated Rogers for the championship on January 24, 1963. After an argument over who should have won, CWC left the NWA and created a new promotion called the World Wide Wrestling Federation (WWWF). The new company then made up a story for its new title, and said that the WWWF World Heavyweight Championship was separated from the NWA World Championship, and there was a tournament in Rio de Janeiro to decide a new champion. They said that Buddy Rogers won this tournament, by beating Antonino Rocca in the finals. (The tournament actually did not happen.) The WWWF came back to the NWA once again, and the WWWF was renamed to World Wrestling Federation (WWF) in 1979. After WWF left the NWA forever in 1983 the championship was named the WWF World Heavyweight Championship and later the WWF World Championship or WWF Championship in the 1990s.
