Starting in 1997 and every year since then the MexicanLucha Libre, orprofessional wrestling,companyAAA has held aRey de Reyes (Spanish for "King of Kings') show in the spring. The 1997 version was held in February,[6] while all subsequent Rey de Reyes shows were held in March. As part of their annual Rey de Reyes event AAA holds theeponymious Rey de Reyes tournament to determine that specific year'sRey.[7] Most years the show hosts both the qualifying round and the final match, but on occasion the qualifying matches have been held prior to the event as part of AAA's weekly television shows.[8] The traditional format consists of four preliminary rounds, each aFour-man elimination match with each of the four winners face off in the tournament finals, again under elimination rules.[6] There have been years where AAA has employed a different format to determine a winner.[8] The winner of the Rey de Reyes tournament is given a large ornamental sword to symbolize their victory, but is normally not guaranteed any other rewards for winning the tournament, although some years becoming the Rey de Reyes has earned the winner a match for theAAA Mega Championship. From 1999 through 2009 AAA also held an annualReina de Reinas ("Queen of Queens") tournament, but later turned that into an actual championship that could be defended at any point during the year, abandoning the annual tournament concept.[9][10][11] The 2011 show was the 15th Rey de Reyes show in the series.
The Rey de Reyes show featured sixprofessional wrestling matches with different wrestlers involved in pre-existing, scripted feuds, plots, and storylines. Wrestlers were portrayed as eitherheels (referred to asrudos in Mexico, those that portray the "bad guys") orfaces (técnicos in Mexico, the "good guy" characters) as they followed a series of tension-building events, which culminated in a wrestling match or series of matches.
