The 2012 International Wrestling Revolution Group (IWRG; Sometimes referred to as Grupo Internacional Revolución in Spanish) anniversary show commemorated the 16th anniversary of IWRG's creation as a wrestling promotion and holding their first show on January 1, 1996. The Anniversary show, as well as the majority of the IWRG shows in general are held in "Arena Naucalpan", owned by the promoters of IWRG and their main arena. The Anniversary Shows generally take place on January 1 each year whenever possible.

The event featured five professional wrestling matches with different wrestlers involved in pre-existing scripted feuds, plots and storylines. Wrestlers were portrayed as either heels (referred to as rudos in Mexico, those that portray the "bad guys") or faces (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.
