Although organized games between all-stars from New York teams against all-stars from Brooklyn teams date back to the 1850s, the first actual New York-Brooklyn "World Championship Series" occurred in 1889, a full nine years before Brooklyn was incorporated into the City of New York by the Greater New York Act of 1898, when the New York Giants squared off against (and defeated) the Brooklyn Bridegrooms, also called the "Trolley Dodgers", of the American Association. The following season, Brooklyn withdrew from the Association and joined the League, setting the stage for many future intra-city competitions.
