WWE Backlash is a professional wrestling pay-per-view event, that was produced every April (with the exception of 2005 and 2016) by WWE, a professional wrestling promotion based in Connecticut. The event was created in 1999, with its inaugural event produced as an In Your House event in April of that year. The event in 2000 was rebranded as an annual PPV event for WWE. To coincide with the brand extension, the event was made exclusive to the Raw brand in 2004. In 2007, to follow the format of WrestleMania, all PPV events became tri-branded. Extreme Rules replaced Backlash in 2010. Backlash was announced as returning as a SmackDown exclusive event in 2016.
