The sport of boxing in the 1930s was affected by one of the biggest economic struggles in the history of the United States: the depression era. Because of the suffering American economy, many boxers were offered lower amounts of money causing them to only box for passion. When the decade began, the world Heavyweight title belonged to no one. The sport of boxing suffered because of the lack of money to pay the boxers.

The Heavyweights, from 1930 to 1937 in particular, could be compared to the Heavyweight division of the 1980s. Six champions were crowned before Joe Louis began his legendary run as Heavyweight champion in 1937. He retired in 1949, still holding the title of world Heavyweight champion.
