What was the Negro Leagues I bet you are asking yourself . Well that is a good question the Negro Leagues was a very popular thing but the best answer is that the Negro Leagues where the Negro Leagues were American professional baseball leagues comprising predominantly African-American teams. The term may be used broadly to include professional black teams outside the leagues and it may be used narrowly for the seven relatively successful leagues beginning 1920 that are sometimes termed "Negro Major Leagues". The first professional team, established in 1885, achieved great and lasting success as the Cuban Giants, while the first league, the National Colored Base Ball League, failed in 1887 after only two weeks due to low attendance. The Negro American League of 1951 is considered the last major league season and the last professional club, the Indianapolis Clowns, operated amusingly rather than competitively from the mid-1960s to 1980s. Here are some pictures of some negro leagues baseball teams.
