WWE Extreme Rules

WWE Extreme Rules was an annual professional wrestling event produced by WWE, a Connecticut-based promotion. It was broadcast live and available only through pay-per-view (PPV) and WWE's livestreaming services. The name of the event stemmed from various matches on the card being contested under hardcore wrestling regulations with generally one match being an Extreme Rules match, which was introduced at the 2010 event. The defunct Extreme Championship Wrestling promotion, which WWE acquired in 2003, originally used the "extreme rules" term to describe the regulations for all of its matches.

The event name was established in 2009; however, its theme began with its predecessor, One Night Stand, which was promoted in 2005 and 2006 as an Extreme Championship Wrestling reunion show. In 2007, WWE promoted the show as one of its own regular PPV events but kept the concept of hardcore-based matches. In 2009, WWE renamed One Night Stand as Extreme Rules. The 2009 Extreme Rules event was noted by WWE to be a direct continuation of the One Night Stand chronology; however, the 2010 event was later promoted as only the second event under a new chronology, one that was no longer a direct continuation of the One Night Stand events.
