Beginning in 2009 the Mexican wrestling promotion International Wrestling Revolution Group (IWRG; Sometimes referred to as "Grupo Internacional Revolución" in Spanish) held an annual show called "Guerra Revolucionaria" ("The Revolutionary War"), a reference to the Mexican revolutionary war (1810–1821). The main event match, the eponymous "Guerra Revolucionaria", a 20-man "over the top" Battle Royal where all 20 wrestlers start out in the ring. Once a wrestler is thrown over the top rope to the floor that wrestler is eliminated from the actual match, from that point on they will act as a "Lumberjack" outside the ring, ensuring that none of remaining competitors try to escape the ring. Each "lumberjack" is given a leather strap that they are allowed to use on anyone that leaves the ring. There is no specific "award" for winning the "Guerra Revolucionaria" tournament. The multi-man match often allows IWRG to intersect various ongoing storylines as another step in the escalating tension. At other times, the match itself was used as a way to start new feuds due to interactions inside or outside the ring. The "Guerra Revolucionaria" shows, as well as the majority of the IWRG shows, in general, are held in Arena Naucalpan, owned by the promoters of IWRG, and it is their main venue. The 2013 "Guerra Revolucionaria" show was the fourth time that IWRG held an event under that label, having not held a "Guerra Revolucionaria" show in 2012. The first three "Guerra Revolucionaria" tournaments did not offer a specific, actual reward to the winner of the match, but for the 2013 tournament IWRG announced that the winner of the match would become the number one contender to the IWRG "Rey del Ring" Championship.
