UFC 100
UFC mixed martial arts event in 2009
UFC 100 was a mixed martial arts event produced by the Ultimate Fighting Championship (UFC) on July 11, 2009, in Las Vegas, Nevada.
This event was the most bought UFC pay-per-view of all time with a buyrate of 1.6 million, until UFC 202 broke the record with 1.65 million.
Background
The event included two championship bouts and a fight between the two coaches on the Spike TV show, The Ultimate Fighter.
The main event was a rematch between UFC Heavyweight Champion Brock Lesnar and Interim UFC Heavyweight Champion Frank Mir. This championship unification bout occurred as a result of former UFC Heavyweight Champion Randy Couture's year-long resignation from the promotion. During his absence, the UFC created an Interim championship, which Antônio Rodrigo Nogueira won by defeating Tim Sylvia. Nogueira and Mir were opposing coaches on The Ultimate Fighter: Team Nogueira vs Team Mir, and fought for the interim championship at UFC 92. During the airing of the television program, Couture returned to the company and UFC President Dana White announced he would defend the title against Lesnar at UFC 91. The winners of the Couture vs Lesnar and Nogueira vs Mir matches would fight for the undisputed title. In his fourth professional fight, Lesnar defeated Couture via technical knockout to become the UFC Heavyweight Champion.

Why this record matters
The phrase “uFC mixed martial arts event in 2009” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Contemporary correspondence, administrative files and participant testimony can test how later narratives organized the event or institution. The source revision retrieved here is dated Aug 30, 2026. The linked authority identifier is Q2296461. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2009.
Institutional narratives can privilege the records that survived while minimizing voices that were never formally collected. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
