WWE Night of Champions was a professional wrestling pay-per-view (PPV) and livestreaming event produced by WWE, a Connecticut-based professional wrestling promotion. The inaugural event took place in June 2007 and was a crossover with Vengeance titled Vengeance: Night of Champions. In 2008, Vengeance was dropped in favor of Night of Champions and it took over the June PPV slot. The event then moved to July in 2009 before becoming the annual September PPV beginning in 2010. The original concept of Night of Champions was that every championship promoted on WWE's main roster was contested. In 2016, Night of Champions was replaced by the similarly themed Clash of Champions which was discontinued after its final use in 2020. After eight years, Night of Champions was revived to be held in May 2023 as WWE's ninth event in Saudi Arabia. Although the 2023 event was based around championship matches, not all of WWE's main roster championships were contested.
