MLB Baseball ( Events)
In the 1860s, aided by the Civil War, "New York" style baseball expanded into a national game and spawned baseball's first governing body, The National Association of Base Ball Players, was formed. The NABBP existed as an amateur league for twelve years. By 1867, more than 400 clubs were members, although most of the strongest clubs remained those based in the northeastern part of the country.
In 1870, a schism developed between professional and amateur ball players after the 1869 founding of the first professional baseball team, the Cincinnati Red Stockings. The NABBP split into two groups. The National Association of Professional Base Ball Players was formed in 1871. Some consider it to have been the first major league.[by whom?] Its amateur counterpart disappeared after only a few years.
In 1876, the National League of Professional Baseball Clubs, which still exists, was established, after the National Association proved ineffective. The emphasis was now on "clubs" rather than "players". Clubs could not enforce player contracts, preventing players from jumping to higher-paying clubs. For their part, clubs were required to play the full schedule of games, instead of forfeiting scheduled games when the club was no longer in the running for the league championship, which happened frequently under the National Association. A concerted effort was made to curb gambling on games which was leaving the validity of results in doubt.
The early years of the National League were tumultuous, with threats from rival leagues and a rebellion by players against the hated "reserve clause", which restricted the free movement of players between clubs. Competitive leagues formed regularly and also disbanded regularly. The most successful was the American Association (1881–1891), sometimes called the "beer and whiskey league" for its tolerance of the sale of alcoholic beverages to spectators. For several years, the National League and American Association champions met in a postseason championship series, the first attempt at a World Series.
