Final answer:
The Negro Leagues were professional baseball leagues primarily made up of African American players that existed from 1920 to 1960. The integration of white 'Major League' baseball in 1947 had a significant impact on the Negro Leagues, leading to their eventual disbandment in the 1960s. However, the integration also brought about positive social change and paved the way for future generations of African American players.
Step-by-step explanation:
The Negro Leagues were professional baseball leagues that existed from 1920 to 1960 and were primarily made up of African American players. They were formed due to the segregation and discrimination in the major leagues that barred black players from participating. The Negro Leagues produced many talented players, such as Josh Gibson and Satchel Paige, and enjoyed popularity and success.
The integration of white 'Major League' baseball in 1947, with Jackie Robinson as the first African American player, had a significant impact on the Negro Leagues. As more black players were allowed to join the major leagues, the talent pool of the Negro Leagues began to decline, leading to a decline in popularity and financial stability. Many fans and supporters shifted their attention to the integrated major leagues, resulting in the eventual disbandment of the Negro Leagues in the 1960s. However, the integration of baseball also brought about positive social change and paved the way for future generations of African American players.
