Then, came World War II, which caused a large percentage of ballplayers to enter the armed forces. This caused a very difficult time for baseball during this period. Since Baseball has always been segregated during this time it opened up a new era for African-Americans to play. Among one of the first to ever play was Jackie Robinson in 1947 for the Brooklyn Dodgers. Baseball just didn"t let hundreds of African-Americans play but it just allowed little by little to play due to the shortage of white ballplayers overseas. To show how long it took for Baseball to actually call itself integrated wasn"t until the early sixties.

             Yet again in 1960 another rival league tried to make it into Baseball. The Continental League wanted to start its own League in the south and west because all the other Leagues were concentrated in the northeast. The Continental League never had a chance to make it to seek a win in court to join the Leagues because it went bankrupt in the first season. The Continental League wasn"t at all a failure because the American and National League were faced with a possibility of losing their monopoly, so they reached a compromise of expanding the League from sixteen teams to twenty-four teams. The players liked this because it meant more jobs. .

             Baseball prospered economically as attendance continued to grow and national television and radio contracts brought in huge amounts of money. But, what the players finally realized was that the owners were the ones making all the money and not them. The players had a union but they never really used it an they all decided to put it to work to make more money for themselves. They hired a guy named Marvin Miller who had fought for the United Steelworkers union for years to help them out. He knew there was more prosperity for the players to gain because the minimum salary for a ball player was $6,000 just a thousand more than in 1947.
