The Ultimate Fighting Championship has changed greatly since its founding in 1993. In its early years, the sport was defined by a simple style versus style format. The fighters typically specialized in disciplines such as boxing, wrestling, karate, or jiu-jitsu, often being inexperienced with techniques outside of their own.[1] In addition, the early years of the organization featured single-night tournaments which required the fighters to compete multiple times in one day.[2] This format displayed the importance of endurance and the benefit of possessing a dominant style. Royce Gracie was the first great UFC champion, as he exhibited the effectiveness of Brazilian jiu-jitsu through defeating much larger opponents.[3] Another UFC star, Ken Shamrock, found success with his grappling, blending wrestling with striking and submissions.[4] The dominance of these fighters emphasized the downfalls of having expertise in a single discipline alone, sparking a steady shift towards more balanced fighting styles. 

   As the sport grew, fighters started to realize the shortcomings of relying on a single discipline. Strikers who struggled with wrestling were vulnerable to being submitted while wrestlers who struggled to strike well were susceptible to being knocked out. The introduction of standardized rules, weight classes, and safety regulations created a much more structured environment, allowing the fighters to develop more balanced skill sets.[5] The athletes increasingly trained in multiple disciplines, mixing techniques to become better fighters. Two fighters who exemplified this change in fighters were Chuck Liddell and Randy Couture. Liddell, who was known for his striking power, improved his takedown defense, allowing him to keep fights on the feet which forced more knockouts.[6] Couture improved his striking, utilizing the ground and pound technique to win many fights.[7] During this period of the sport, striking grew a much more popular discipline in order to combat the dominance of wrestling and jiu-jitsu. The more balanced fighters made the contests much more exciting with an increase in knockouts and much more competitive engagements.[8] Though future fighters would make even more improvements, this was a big step forward for the UFC in developing true mixed martial artists. 

   The UFC continued to develop, with an increase of fighters training in multiple disciplines from the start of their careers, leading to better competition. At a time when the sport was struggling to gain popularity, the debut of the reality show, The Ultimate Fighter, played a critical role in boosting viewership of the organization as well as attracting a generation of increasingly complete fighters.[9] As a result, the combatants had significantly fewer weaknesses, as they were increasingly proficient in fighting strategy. This new era of UFC fighters resulted in names such as Georges St. Pierre, Anderson Silva, and Jon Jones. While Silva demonstrated excellent defensive grappling skills, he reached unmatched levels with his creative striking ability, eventually winning a record 16 straight fights.[10] St. Pierre was a master strategist, combining respectable striking with devastating wrestling that demoralized and tired his opponents.[11] Jones utilized his reach, creativity, and versatility to dominate opponents in all areas of the fight and become the youngest champion in UFC history at the age of 23.[12] All of these fighters showed the great ability to adapt to many different situations which would greatly intimidate the challengers. From this era forward, in order to fight in the UFC, the fighters had to possess the ability to integrate all aspects of fighting into their bouts.  

   Conor McGregor rose to fame in the mid-2010s as the face of the UFC. McGregor is one of the most entertaining fighters to ever fight for the organization due to his elite striking power magnified through perfect timing.[13] McGregor was extremely confident and utilized this to mentally overcome his opponents as well as physically. His ability to psychologically affect the other fighters gave him an edge in combat.[14] He used this advantage to his benefit, as his 2015 victory over dominant champion Jose Aldo lasted only 13 seconds.[15] In 2016, he became the first fighter to ever hold two championship titles at once.[16] He had a massive, global fanbase, including his countrymen of Ireland that brought increased attention to the UFC, solidifying it as a popular international sport.[17] The rise of McGregor sparked a new shift in which fighters were not only expected to be balanced competitors, but also marketable personalities capable of drawing large audiences. 

   These developments represent many key milestones in the evolution of the Ultimate Fighting Championship. The steady progression of the fighters’ skill corresponded with the organization’s growth. Since its founding, the sport transformed from singular fighting style versus style into one defined by balanced athletes skilled in a multitude of disciplines, helping the UFC’s rise as a global competition.
