UFC 221
UFC mixed martial arts event in 2018
UFC 221: Romero vs. Rockhold was a mixed martial arts event produced by the Ultimate Fighting Championship that was held on February 11, 2018, at Perth Arena in Perth, Australia.
Background
While the UFC has hosted 11 previous events across the country, the event marked the promotion's first visit to Perth, in Western Australia, after the state government overturned its ban on cage fighting.
In order for the event to be broadcast live during prime time hours on the east coast of North America, the main card began at 11:00 a.m. local time in Perth WST, with a full preliminary card beginning at approximately 7:00 a.m. local time.
While not officially announced by the promotion, a UFC Middleweight Championship unification bout between then champion Georges St-Pierre (who is also a former two time UFC Welterweight Champion) and interim champion Robert Whittaker (also The Ultimate Fighter: The Smashes welterweight winner), was initially targeted to serve as the event headliner. However, St-Pierre later indicated that he was currently mulling his future in the division and announced that he expected to be out indefinitely after being diagnosed with ulcerative colitis. Subsequently, St-Pierre vacated the championship on December 7 and Whittaker was promoted to undisputed champion. Whittaker was then expected to defend the championship against former Strikeforce and UFC Middleweight Champion Luke Rockhold in the main event.
This brief starts where responsible research should: with the source description of “UFC 221” as uFC mixed martial arts event in 2018. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the history & society register because the source frames it as uFC mixed martial arts event in 2018. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Chronology, provenance and viewpoint should be read together before a broad social or political interpretation is accepted. The source revision retrieved here is dated May 5, 2026. The linked authority identifier is Q47477773. The first chronological checks are 2018.
Later summaries often reconcile disputed chronology or motive more neatly than the contemporary record permits. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
