WWE Championship
The original world championship of the promotion, it was established by the then-World Wide Wrestling Federation (WWWF) on April 25, 1963 as the WWWF World Heavyweight Championship, following the promotion seceding from the National Wrestling Alliance (NWA). The inaugural champion was Buddy Rogers. Since its inception, the title has undergone many name changes due to company name changes and title unifications. It is the oldest championship currently active in the WWE, and is presented as being the promotion's most prestigious title, with many matches for the title having headlined pay-per-view events – including WWE's flagship event WrestleMania. In professional wrestling in general, it is considered by many to be one of the most prestigious championships of all time.
