In 1999, the World Wrestling Federation (WWF, now WWE) held a pay-per-view (PPV) entitled Backlash as the post-WrestleMania XV event.

[4][5][6] The event featured nine professional wrestling matches that involved different wrestlers from pre-existing scripted feuds and storylines.

The Regime's new objectives primarily revolved around keeping Triple H as WWF Champion through dirty tactics of interfering in matches, and ambushing dissenters at inopportune times.

The distraction allowed Jericho to take advantage and pin Triple H to win the title, though Hebner visibly called a fast pinfall.

Later that night, WWF CEO Linda McMahon, the only member of the McMahon family to not be a member of The Regime, arrived to the arena and announced that she declared The Rock to be "outnumbered" at Backlash, and decided that she would allow one WWF wrestler to be in The Rock's corner at Backlash.

prior to Backlash, Austin made his first WWF appearance in 6 months, where he dropped a concrete barrier from a crane onto the "DX Express" bus, causing it to explode, as a warning to the Regime.

- The event opened with Edge and Christian defending the WWF Tag Team Championship against D-Generation X (X-Pac and Road Dogg).

After Matt and Jeff dove onto Saturn and Hardcore Holly, Crash pinned Tazz to retain the title.

In the main event, Triple H defended the WWF Championship against The Rock with Shane McMahon as the special guest referee.

Triple H then performed a Pedigree on The Rock whilst Pat Patterson and Gerald Brisco appeared to officiate the match.

Stone Cold Steve Austin then appeared and hit Triple H, Patterson, Brisco, Shane and Vince with a chair.

In 2015, Kevin Pantoja of 411Mania gave the event a rating of 9.0 [Amazing], stating "Not only is this among the best non Big Four Pay-Per-Views ever, but it’s also one of the best PPVs ever, period.

The Undertaker, now in a new biker gimmick, joined The Rock in a feud with The Regime, with Kane joining in as well, which culminated in a 3-on-3 tag team match at King of the Ring against Triple H, Vince, and Shane, where The Rock once again won the WWF Championship by pinning Vince.

Meanwhile, Stone Cold Steve Austin would not appear on WWF television again until September at Unforgiven, when he would start to investigate who ran him over at the Survivor Series the year before.
