The first UFC event was held in 1993 in Denver, Colorado. The purpose of the event was to identify the most effective martial art in a real fight between competitors of different fighting disciplines, including Boxing, Brazilian Jiu-Jitsu, Tae Kwon Do, Wrestling, Muay Thai, Karate and other styles. In subsequent competitions, fighters ventured outside their base style to utilize effective techniques from other disciplines, which indirectly helped create an entirely separate style of fighting known as present-day mixed martial arts.
