The team name, Brooklyn Trolley Dodgers, was coined in 1895. The nickname was still new enough in September 1895 that a newspaper could report that “‘Trolley Dodgers’ is the new name which eastern baseball cranks [fans] have given the Brooklyn club.” In 1895, Brooklyn played at Eastern Park, bounded by Eastern Parkway (now Pitkin Avenue), Powell Street, Sutter Avenue, Van Sinderen Street, where they had moved early in the 1891 season when the second Washington Park burned down. Some sources erroneously report that the name “Trolley Dodgers” referred to pedestrians avoiding fast cars on street car tracks that bordered Eastern Park on two sides. However, Eastern Park was not bordered by street-level trolley lines that had to be “dodged” by pedestrians. The name “Trolley Dodgers” implied the dangers posed by trolley cars in Brooklyn generally, which in 1892, began the switch from horse-power to electrical power, which made them much faster, and were hence regarded as more dangerous. The name was soon shortened to Brooklyn Dodgers.

For most of the first half of the 20th century, no Major League Baseball team employed a black player. A parallel system of Negro Leagues developed, but most of the Negro League players were denied a chance to prove their skill before a national audience. Jackie Robinson became the first African-American to play Major League baseball in the 20th Century when he played his first major league game on April 15, 1947 as a member of the Dodgers. Robinson’s entry into the league was mainly due to General Manager Branch Rickey’s efforts. The deeply religious Rickey’s motivation appears to have been primarily moral, although business considerations were also present. Rickey was a member of The Methodist Church, the antecedent denomination to The United Methodist Church of today, which was a strong advocate for social justice and active later in the Civil Rights movement.

The 1955 World Series matched the Brooklyn Dodgers against the New York Yankees, with the Dodgers winning the Series in seven games to capture their first championship in franchise history. It would be the only Series the Dodgers won in Brooklyn the team relocated to Los Angeles after the 1957 season.
