Tony Bellew became the 13th British man to hold a world title after he was crowned WBC cruiserweight champion with a thrilling third-round stoppage of Ilunga Makabu at Goodison Park on Sunday night.
Here Press Association Sport looks at the other men from Britain who are currently world champions and how they did it:
TYSON FURY (HEAVYWEIGHT)
Not many gave the Mancunian much chance of dethroning heavyweight kingpin Wladimir Klitschko, but Fury utilised his size advantage to make his opponent look every one of his 39 years and claimed the WBA, WBO and IBF titles with a deserved unanimous decision victory in Dusseldorf last November.
ANTHONY JOSHUA (HEAVYWEIGHT)
Fury's decision to rematch Klitschko instead of facing his mandatory challenger Vyacheslav Glazkov meant he vacated his IBF strap, which Charles Martin clinched by defeating Glazkov. Martin opted to make his first defence against the heavy-handed Joshua, who ruthlessly took his chance in just his 16th professional fight by stopping the overmatched American inside two rounds at London's O2 Arena last month.
JAMES DEGALE (SUPER-MIDDLEWEIGHT)
DeGale became the first Briton to combine winning an Olympic gold medal with a world title when he travelled to Boston to defeat Andre Dirrell in April last year. The Londoner seemed on course for an easy night's work when he dropped Dirrell twice in round two but the American rallied to go the distance. DeGale, however, had done enough to claim the vacant IBF title after getting the nod from all three judges.
BILLY JOE SAUNDERS (MIDDLEWEIGHT)
The unbeaten Saunders earned the WBO strap with a hard-fought majority decision win over London-born Irishman Andy Lee last December. Saunders knocked Lee down twice in the third round but had to survive a few nervy moments down the stretch before coming out on top at the Manchester Arena.
LIAM SMITH (LIGHT-MIDDLEWEIGHT)
The first of the four Smith brothers from Liverpool to win a world title, but surely not the last. Liam stopped America's John Thompson inside seven rounds to win the vacant WBO title at the Manchester Arena in October last year.
KELL BROOK (WELTERWEIGHT)
The Sheffield fighter had seen three world title challenges fall by the way side due to injury but he seized his chance when he travelled to California in August 2014 to snatch the IBF belt from Shawn Porter. The American started strongly but Brook, a big underdog, kept his composure and finished strongly to earn a majority decision win.
RICKY BURNS (LIGHT-WELTERWEIGHT)
Burns had lost three of his last six fights and was declared bankrupt in 2015 but he put himself back in the big time by stopping Italy's Michele Di Rocco in eight rounds in Glasgow on Saturday to win the vacant WBA 'super' title and, in the process, become Scotland's first three-weight world champion.
TERRY FLANAGAN (LIGHTWEIGHT)
Flanagan claimed the vacant WBO strap when American foe Jose Zepeda suffered a dislocation of his left shoulder and remained on his stool at the end of the second round at Manchester's Velodrome last July.
ANTHONY CROLLA (LIGHTWEIGHT)
Less than a year after fracturing his skull when confronting burglars, Crolla knocked out Colombia's Darleys Perez in the fifth round of their rematch, after their first bout was ruled a controversial draw, with a body shot to land the WBA 'world' crown in front of a raucous crowd at the Manchester Arena last November.
LEE SELBY (SUPER-FEATHERWEIGHT)
The slick Welshman put on a masterclass in taking Evgeny Gradovich's IBF belt last May at the O2 Arena, winning a technical decision after the fight was halted in the eighth round due to a cut above the Russian's left eye following a clash of heads.
JAMIE McDONNELL (BANTAMWEIGHT)
The Doncaster man won the vacant WBA 'world' title after stopping Tabtimdaeng Na Rachawat of Thailand in the 10th round with a peach of a left hook on the same night Carl Froch defeated George Groves on a heady night at Wembley Stadium in May 2014.
LEE HASKINS (BANTAMWEIGHT)
The only man on the list to be crowned champion out of the ring, awarded the IBF belt last November after Randy Caballero was stripped of the title for failing to make weight.
