On various occasions in professional wrestling, a single-elimination tournament of varying match types are held, often to determine a championship or number-one contendership therein. It has been known for promotions to use title tournament that are fictitious in nature (that is, the title may have been simply awarded under the pretext of winning a tournament elsewhere) - notable ones include the tournaments that established the WWE World Heavyweight Championship, the WWE Intercontinental Championship, and the WWE United States Championship (the latter when it was the NWA United States Championship).
