BIOGRAPHY
Joseph William Calzaghe CBE (born 23 March 1972) is a Welsh former professional boxer who competed from 1993 to 2008. He held multiple world championships in two weight classes, including unified and lineal titles at super-middleweight, and the Ring magazine light-heavyweight title. Calzaghe is the longest-reigning super-middleweight world champion in boxing history, having held the World Boxing Organization (WBO) title for over 10 years and defending it against 20 opponents (a record in the division) before moving up to light-heavyweight. As his super-middleweight and light-heavyweight reigns overlapped, he retired with the longest continual time as world champion of any active boxer at the time. Calzaghe was the first boxer to unify three of the four major world titles (World Boxing Association, World Boxing Council, and WBO) at super-middleweight, and was the inaugural Ring champion in that weight class. He retired in February 2009 with an undefeated record of 46 wins, and as a reigning world champion.
