At the time of the [[Ultimate Fighting Championship|UFC]]'s inception in 1993, the sport of [[mixed martial arts]] was unsanctioned in the United States, and it did not include [[weight classes]]. Instead of the traditional championship model, tournaments were held with the winner receiving a permanent appellation.<ref>{{cite web

The original codification for weight classes introduced only two divisions: [[heavyweight]], which grouped competitors above {{convert|200|lb|kg|lk=off}}, and lightweight, which encompassed all other competitors. The UFC would later rename its lightweight division to [[Light Heavyweight (MMA)|middleweight]] and add [[Welterweight (MMA)|lightweight]] {{convert|170|lb|kg|lk=off}} and [[Lightweight (MMA)|bantamweight]] {{convert|155|lb|kg|lk=off}} divisions. In 2000, the [[New Jersey State Athletic Control Board]] completely took over regulation in its home state, and its [[Mixed martial arts rules#Unified Rules of MMA|rules and weight classes]] became the ''[[de facto]]'' rule set for mixed martial arts.<ref>{{cite web

At the time of the [[Ultimate Fighting Championship|UFC]]'s inception in 1993, the sport of [[mixed martial arts]] was unsanctioned in the United States, and it did not include [[weight classes]]. Instead of the traditional championship model, tournaments were held with the winner receiving a permanent appellation.<ref>{{cite web

The original codification for weight classes introduced only two divisions: [[heavyweight]], which grouped competitors above {{convert|200|lb|kg|lk=off}}, and lightweight, which encompassed all other competitors. The UFC would later rename its lightweight division to [[Light Heavyweight (MMA)|middleweight]] and add [[Welterweight (MMA)|lightweight]] {{convert|170|lb|kg|lk=off}} and [[Lightweight (MMA)|bantamweight]] {{convert|155|lb|kg|lk=off}} divisions. In 2000, the [[New Jersey State Athletic Control Board]] completely took over regulation in its home state, and its [[Mixed martial arts rules#Unified Rules of MMA|rules and weight classes]] became the ''[[de facto]]'' rule set for mixed martial arts.<ref>{{cite web
