The Ultimate Fighting Championship (UFC) is the biggest MMA promo in the world and is a U.S. based Mixed Martial Arts (MMA) organization. The UFC's headquarters are in Las Vegas, Nevada.
The first event was at the McNichols Sports Arena in Denver, Colorado and the goal was to determine the most effective martial art contest in a minimally regulatory and weightless contest. Contestants had to compete in various sports such as boxing, karate, kickboxing, Muay Thai, Brazilian jiu-jitsu, wrestling, taekwondo, sambo.
November 12, 1993, was when the first event of the UFC, the UFC 1 was held. The rules state that there are multiple fights in each UFC event. Any action usually begins with a preliminary card followed by a main card, which is known as the big event with the last fight.
How many fights are before the Main Event?
The events held before the main event are called undercards. These bouts typically last between four and eight rounds, depending on the experience of the boxers in such matches (entry-level boxers, often making professional debuts, have four rounds, while middle-level boxers are given between six and eight rounds), with some undercards on major championship cards being ten rounds if the fighter is at an advanced level but not at par.
If the undercard match is a title match (less common weight class or provincial championship), the undercard match is often twelve rounds, according to the rules. The Early Prelims, Prelims, and Main Events (shown in that order) each contain about five fights, with the best fights reserved for the Main Event. The Early Prelims usually feature three fights, but they can feature four fights on rare occasions.
The Prelims normally have four matches and sometimes even five. The fight is set for 15 minutes, as in non-title fighting. That means an hour of full combat time. The difference between the Early Prelims and the ordinary Prelims is that the Prelim fighters are revealed at the Octagon and interviewed at that time.
