Boxing is not confined to America only, as it is a global sport adopted by many across continents. Europe has a fair share of outstanding sports personalities who left their marks on boxing history. Many boxers ruled the world during their era by showing brilliant success and approach towards the sport. One good knockout can make any boxer a star in the boxing world. Still, there is a long journey to cover for being called a superstar to join an elite list of legendary boxers. Boxing skills, win/loss records, knockout finishes, and the overall legacy of a boxer are the main focus of this list.

10 Jimmy McLarnin

Jimmy McLarnin is an Irish-born boxer made famous by his nickname 'The Dublin Destroyer.' With his orthodox boxing style, McLarnin reached the peak of the boxing world from 1923 to 1936. T]One of the toughest and the bravest welterweights, the boxer had a career record of 55-11-3 with 21 wins by way of knockout. From ruling Madison Square Garden to winning the welterweight championship, McLarnin served the sport of boxing with his unique style and accuracy in delivering punches and hooks. His trilogy with another boxing great, Barney Ross, remains a shining highlight for boxing fans.

9 Benny Lynch

Benny Lynch is a perfect example of 'failure is not fatal, but failure to change might be.' Lynch has been long considered the greatest flyweight in Europe with a career record of 88-14-17 with 34 knockouts. Lynch, however, had more focus on alcohol than on his boxing career. Despite this, he toppled the flyweight legends of his era in boxing charts with 119 fights in only 7 years. The best flyweight of the 1930s lacked the good fortune to carry on with his success in boxing, as Lynch would die at age 33 from hypothermia and alcoholism.

8 Ken Buchanan

Starting from 33 straight victories to ending in 4 back-to-back losses, Ken Buchanan gave unforgettable memories to the boxing fans. Buchanan won lightweight titles across promotions with a record 61-8 with 27 knockouts. A premature retirement in 1978 was the real culprit behind the decline in his boxing career. Ken 'The Fighting Carpenter' Buchanan was added to the Scottish Sports Hall of Fame and International Boxing Hall of Fame for his services to the sport.

7 Marcel Cerdan

His tragic death could not vanish the greatness Marcel Cerdan had in boxing. Cerdan is ranked as the best French Boxer to step foot on Earth.

Cerdan left a great legacy as a boxer and a warrior in World War II.

6 Lennox Lewis

At nearly 84 inches, Lennox Lewis possesses one of the longest reaches among the top boxers in the world.

The younger brother, Wladimir Klitschko, had 19 straight victories in heavyweight championship defenses for multi-promotional titles. Finishing at a career record of 64-5 with 53 knockouts, he is classified as one of the best heavyweights with the ability to knock out his opponents. The Ukrainian boxer built a strong legacy in the boxing world before retiring in 2017 after two back-to-back losses at the hands of Tyson Fury and Anthony Joshua. His greatness doesn't exist solely in the squared circle, though - Wladimir Klitschko is a hero outside the boxing ring as well

Calzaghe ended his career with a record 46 wins, with 32 of those coming from knockouts. Known as 'The Terminator,' he was the longest continual champion among active boxers before his retirement. Joe Calzaghe is among the best 30 Boxers of All Time, according to TheSportster.

2 Rob Fitzsimmons

The 'Frightening Blacksmith' Rob Fitzsimmons was the first three-division world champion in boxing. Fitzsimmons took his opponents down early in his bouts with his stiff strikes and hard punches.
