Over the past decade, the WEC has succeeded in spotlighting lighter weight fighters as well as the creating of stars such as Urijah Faber, Jose Aldo and Miguel Torres, whom otherwise might not have received the same amount of recognition.
Let's take a look back at the history of the WEC after the jump.
June 30, 2001 -- Answering a call from the Tachi Palace Hotel & Casino (then the The Palace Indian Gaming Center) in Lemoore, Calif. for MMA events at the venue, Scott Adams and Reed Harris start up World Extreme Cagefighting and the first event is headlined by Dan Severn vs. Travis Fulton. Leonard Garcia, who has stayed with the WEC until the end, is in the second fight of the night and wins by knockout.
Aug. 31, 2002 -- At WEC 4, the promotion runs a show at the Mohegan Sun in Uncasville, Conn., the first and only time, the WEC pre-Zuffa, would leave California.
March 27, 2003 -- At WEC 6, the WEC promotes its most publicized show to date, setting the stage for the return of Frank Shamrock after a three-year absence. It was Shamrock's first fight in the States since "retiring" as UFC champion in 1999. In the main event of Return of a Legend, Shamrock defeats Bryan Pardoe to become the first-ever WEC light heavyweight champion. After the fight, Shamrock would take another three years off until his full-time return with Strikeforce in 2006.
