Welcome to TSE: WBO/WBA ( Boxing )

Modern boxing can be said to have started when in 1892 James J Corbett defeated John L Sullivan with a KO in the 21st round. James J Jeffries reigned undisputed from 1899 to 1905 and Jack Johnson regigned from 1908 to 1915. The next star came along in the likes of Jack Dempsey who was the undisputed champion from 1919 to 1926.

From 1964 to 1970 only Muhammad Ali would hold the distinction of being undisputed ( 1964 and 1967 ). Between 1970 and 1978 the heavyweight title would see 4 boxers hold the undisputed title ( Joe Frazier 70-73, George Foreman 73-74, Muhammad Ali 74-78, and Leon Spinks 78 ), however...the title would remain disputed until Mike Tyson in 1987 defeated Tony Tucker. The days of a fighter holding the title exclusively for more than a year or two were gone.
