WWE Backlash is a professional wrestling event that is produced by the American company WWE, the world's largest professional wrestling promotion. It is broadcast live and has been available through pay-per-view (PPV) since 1999 and via livestreaming since 2016. Since premiering in 1999, 19 events have been held, with its most recent 19th edition occurring at the LDLC Arena in Décines-Charpieu in the Metropolis of Lyon, France on May 4, 2024. With the exception of the events held from 2016 to 2020, the concept of the show is based around the backlash of WWE's flagship event, WrestleMania.
The inaugural Backlash in April 1999 was the company's first monthly PPV held after the discontinuation of the original In Your House shows, which were monthly PPVs held between the promotion's "Big Five" PPVs at the time: Royal Rumble, WrestleMania, King of the Ring, SummerSlam, and Survivor Series. The inaugural event had originally been advertised as an In Your House show, but the branding was dropped before the event took place. From its inception until 2009, Backlash held the position as the post-WrestleMania PPV and was held annually in April, with the exception of the 2005 event, which was held in May. After the 2009 event, Backlash was discontinued and replaced by Extreme Rules in 2010, but after seven years, it was reinstated in 2016 and held in September as that year's post-SummerSlam PPV. The events in 2017 and 2018 were then held in May, but were not the post-WrestleMania PPVs. An event was originally scheduled for June 2019 but was canceled and replaced by a one-off event called Stomping Grounds. Backlash then returned in 2020 and was held that June. The 2021 event moved Backlash back to May as the post-WrestleMania 37 PPV, thus the event returned to its original concept with the 2021 and 2022 events titled as WrestleMania Backlash, but the 2023 event reverted to its original name while maintaining the post-WrestleMania theme. In addition to this theme, the 2024 event was titled Backlash France as it was WWE's first PPV and livestreaming event held in France, as well as the first Backlash held outside of North America.
The 2002 event was WWE's first PPV held following the implementation of the original brand extension the month prior. With the brand split in effect, the events in 2002 and 2003 featured wrestlers from both the Raw and SmackDown brands, but from 2004 to 2006, Backlash was held exclusively for the Raw brand. Following WrestleMania 23 in 2007, brand-exclusive PPVs were discontinued, thus the events from 2007 to 2009 featured wrestlers from Raw, SmackDown, and ECW, the latter of which was established as a third brand in 2006 but was disbanded in 2010. The brand split itself ended in 2011, but was reintroduced in mid-2016. Backlash was then reinstated as a SmackDown-exclusive PPV that year and was WWE's first brand-exclusive PPV of the second brand split, and it was also SmackDown-exclusive in 2017. Following WrestleMania 34 in 2018, brand-exclusive PPVs were again discontinued, thus the events since have featured both the Raw and SmackDown brands.
