The Mexican Lucha libre, or professional wrestling promotion International Wrestling Revolution Group (IWRG) has produced and scripted a number of wrestling shows since their creation on January 1, 1996 by promoter Adolfo "Pirata" Moreno. Some of these shows have become annual events, some are special one-off events, normally indicated by a special main event match or being promoted under a special name, and some are IWRG's normally scheduled Wednesday or Sunday shows. Many of the annual and special events are headlined by a Lucha de Apuestas, or "bet match", where a wrestler will put his wrestling mask or hair on the line.
The longest-running recurring IWRG show is the Arena Naucalpan Anniversary Show, which started in 1978, making it the second longest-running professional wrestling recurring show series, only surpassed by the Consejo Mundial de Lucha Libre Anniversary Shows that began in 1934. It is the only regular IWRG show that predates the creation of IWRG itself. IWRG's second-longest-running show is their IWRG Anniversary Shows, starting on January 1, 1997, and held within the first couple of days of January. Throughout the year IWRG promotes several other recurring events such as the El Castillo del Terror ("The Tower of Terror"), Legado Final ("Final Legacy") or Guerra del Golfo ("The Gulf War"). They also hold several annual tournament such as El Protector, Rey del Ring ("King of the Ring") and Rebelión de los Juniors amongst others.
