Conor McGregor Birthplace and Early Life

Conor Anthony McGregor was born on July 14, 1988, in Crumlin, Ireland. As a child, he was talented in sports, especially football. However, it was not until he was 12 years old that he started training at a boxing club. 

In 2006, now aged 17 – McGregor’s family relocated to Lucan, Dublin. Here, he began an apprenticeship in plumbing. Through this work, he met Tom Egan, who was a UFC fighter. The two soon began training together. 

McGregor also practiced under John Kavanag, who competed in professional mixed martial arts (MMA) and was the first Irishman to obtain the rank of black belt in Brazillian Jiu-jitsu. 

At the age of 18, McGregor made his debut in MMA. He won his first fight in the first round by TKO.

Over the next few years, McGregor went on to achieve an impressive record of 12-2 and won the CWFC Featherweight and Lightweight Championships – making him the first fighter from Europe to ever hold two world titles from two separate divisions simultaneously. 

After this feat, UFC had taken note and offered McGregor a multi-fight contract – making him just the second Irish fighter ever to participate, after fellow coach and fighter Tom Egan.

Now aged 24, McGregor made his debut in the UFC Featherweight division against Marcus Brimage. In the first round, after just over a minute, McGregor won the fight by TKO. This win also earned him the first Knockout of the Night award.

McGregor shortly went on to beat his second opponent Max Holloway after this, but unfortunately suffered an injury, leaving him unable to compete for 10 months.

McGregor returned after his injury to another win and the ‘Performance of the Night’ award, followed by two more back-to-back victories and awards against Dustin Poirier and Dennis SIlver. 

McGregor’s recent performances had now pushed him to be the top challenger for the Featherweight Championship against Jose Aldo. 

The UFC president, Dana White, had mentioned that this would be the highest-paid and most promoted UFC event of all time. Unfortunately, due to a rib fracture two weeks before the event, Aldo had to pull out.

Instead, McGregor fought Chad Mendes for the Interim Featherweight Championship, winning the championship and Performance of the Night award again.

McGregor eventually had the opportunity to face Jose Aldo in December 2015, and won the match in 13 seconds within the first round. This was the fastest win in the history of the UFC.

McGregor went on to win the Lightweight Championship in 2016 against Nate Diaz. But was eventually stripped of his Featherweight and Lightweight titles due to inactivity.

Two of McGregor’s most highly watched and memorable matches have been against Floyd Mayweather and Khabib Nurmagomedov.

McGregor was largely inactive in the UFC at this time due to him having his first child. However, he was also attempting to set up a fight with the undefeated boxer, Floyd Mayweather.  

After much hype in the build-up, the boxing match finally took place in August 2017, where Mayweather eventually won the fight after 10 rounds. 

The event itself was one of the biggest events and biggest paydays of all time, attracting 4.3 million pay-per-view purchases. 

McGregor had also had a long rivalry with the Russian undefeated champion, Khabib Nurmagomedov over the years, and the two finally competed against each other inside the ring in October 2018. 

Conor lost the fight in the fourth round. However, the event itself gained much attention and coverage for the UFC.

Conor McGregor Retirement and Post-Professional

McGregor has currently retired from fighting three times, in 2016, 2019, and 2020.

In March 2019, McGregor issued a Twitter post stating he would be retiring again.

However, this was also short-lived. McGregor came back to the UFC in January 2020 to fight in two more matches, a win against Donald Cerrone, followed by a loss to Dustin Poirier.

McGregor retired for a third time in June 2020. Although there is suspicion he may return to UFC in the near future, he remains retired at the time of writing.
