Katie Taylor has won a record-equalling fifth consecutive world title at the AIBA Women's World Boxing Championships in Jeju, South Korea.
The Bray woman secured the gold once more with a victory over Azerbaijan’s Yana Allekseevana in the lightweight final early on Monday morning.
Taylor was aggressive from the opening bell but her taller, southpaw opponent countered well in the first round.
Two of the three judges had Taylor ahead 10-9, with the other giving it 10-9 to her rival.
Taylor cranked up the pressure in the second round, landing a crunching right hook on Allekseevna and winning the round on all three cards.
Allekseevna showed more in the third, but Taylor landed a series of combinations to get the verdict from two of the judges once more and take a 30-27, 29-28, 29-28 lead heading into the final round.
The Azerbaijani looked tired but was forced to go on the offensive in search of a stoppage.
"It was very tight but it's an absolute privilege to equal Mary Kom's record, she's a hero of the sport." - Katie Taylor
She wasn't able to hurt Taylor however, and the Irish woman counter-attacked ruthlessly to seal an assured victory on a 40-36, 39-37, 39-37 scoreline.
Taylor's stunning achievement brings the 2012 Olympic champion level with Indian great Mary Kom on five world crowns.
The 28-year-old has also won six European and five EU titles for a total of 17 major titles.
"I'm absolutely delighted," she said afterwards. "It was such a tight contest. Every round was very close and very tricky.
"The tactics from my Dad and Zaur (Antia) were spot-on and I had to execute the game plan so well.
"It was very tight but it's an absolute privilege to equal Mary Kom's record, she's a hero of the sport.
"I thank God for another great victory. I know everyone at home was praying for me as well and that was so encouraging and reassuring."
Taylor immediately vowed to try and claim a sixth world title and second Olympic medal in 2016.
"Every championship is so hard to win and to defend," she said. "I know how hard it is to win one world title so to keep defending it is a huge challenge.
"I'm going to try to defend my Olympic title now and try to make history again."
President Michael D Higgins led the praise for the five-time champion.
"All of us are so proud of her," he said in a statement.
"I offer sincere congratulations to Katie and indeed her family on this outstanding win, where she again showed such remarkable skill, determination and courage at the very highest level.
"Katie Taylor is without doubt the outstanding Irish sportswoman of her generation and has set a standard for all Irish sports people to follow in decades ahead."
