 WWF took full advantage of their situation, unifying the unbranded "World Championship" (formerly the WCW World Heavyweight Championship) and WWF Championship at Vengeance in 2001, with Chris Jericho becoming the first Undisputed WWF Champion (and the first undisputed champion in over 50 years in professional wrestling in general).The championship was then represented by the belts of its two predecessors until a singular belt design was commissioned.By May 2002, the WWF had been renamed to World Wrestling Entertainment and the Undisputed WWE Championship, as it was now called, became the top championship of the promotion.
