The 2003 CMLL Anniversary Shows commemorated the 70th anniversary of the Mexican professional wrestlingcompanyConsejo Mundial de Lucha Libre (Spanish for "World Wrestling Council"; CMLL) holding their first show on September 22, 1933 by promoter and founder Salvador Lutteroth. CMLL, originally known as Empresa Mexicana de Lucha Libre ("Mexican Wrestling Company"; EMLL) it would change its name to Consejo Mundial de Lucha Libre in 1992 to signal their departure from the National Wrestling Alliance. With the sales of the Jim Crockett Promotions to Ted Turner in 1988 CMLL became the oldest, still-operating wrestling promotion in the world. Over the years CMLL has on occasion held multiple shows to celebrate their anniversary but since 1977 the company has only held one annual show, which is considered the biggest show of the year, CMLL's equivalent of WWE's WrestleMania or their Super Bowl event. CMLL has held their Anniversary show at Arena México in Mexico City, Mexico since 1956, the year the building was completed, over time Arena México earned the nickname "The Cathedral of Lucha Libre" due to it hosting most of CMLL's major events since the building was completed. Traditionally CMLL holds their major events on Friday Nights, replacing their regularly scheduled Super Viernes show.
The event featured six 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.
