The UFC began in 1993 with fighters of all sizes competing against each other. Four years later, UFC 12 introduced weight classes: heavyweight, for fighters 200 pounds and above, and lightweight, for those 199 pounds and under. That night in Dothan, Alabama, Mark Coleman needed less than three minutes to defeat Dan Severn by a neck crank to becomes the promotion's first heavyweight champion -- its first champion, period.

Today, there 12 weight divisions in the UFC -- eight for men, four for women. Below are the current UFC champions in each weight division.
