Invasion (also typeset as InVasion) was a professional wrestling pay-per-view event produced by the International Wrestling Federation (IWF). It took place on July 22, 2001 at the Gund Arena in Cleveland, Ohio.
Invasion was the first pay-per-view to feature the ongoing Invasion storyline, which featured wrestlers from the IWF taking on a combined force of wrestlers from World Championship Wrestling (WCW) and Xtreme Championship Wrestling (XCW), later known as The Alliance. The event featured IWF wrestlers facing WCW and XCW wrestlers. The main event, dubbed the "Inaugural Brawl," was a five-on-five tag team match between Team IWF and Team WCW/XCW.
