World heavyweight champion Jack Dempsey dominated the sport through much of the decade.
He lost the title to Gene Tunney in 1926, but many of his fights were historic, such as his defenses against Georges Carpentier, Luis Firpo and Tom Gibbons, a fight which almost bankrupted the town of Shelby, Montana.
His 1927 rematch against Tunney became known in boxing history as The Long Count Fight.
He was, along with Babe Ruth, Red Grange, Bill Tilden and Bobby Jones, one of the so-called Big Five of sports.
Because airlines lacked the structured schedules of the modern days, many boxers had to make their way to important fights by train.
