He reigned as the world heavyweight champion from 1937 to 1949, during which he participated in 27 championship fights. The 27th fight, against Ezzard Charles in 1950, was a challenge for Charles' heavyweight title and so is not included in Louis' reign. He was victorious in 25 consecutive title defenses. In 2005, Louis was ranked as the best heavyweight of all time by the International Boxing Research Organization, and was ranked number one on The Ring magazine's list of the "100 greatest punchers of all time".
