Definition of National league

The National League of Professional Baseball Clubs, or simply the National League, is the older of two leagues constituting Major League Baseball in the United States and Canada  and the world's oldest extant professional team sports league. Founded February 2, 1876 to replace the National Association of Professional Base Ball Players, it is sometimes called the Senior Circuit in contrast to the "junior circuit" of the American League, founded in 1900-1901. The two league champions of 1903 arranged to meet in the World Series and, after the 1904 champions failed to do likewise, the two leagues have arranged for to meet in that annual culmination of the American baseball season, failing to do so only in the strike-shortened 1994 season. National League teams have won 42 and lost 60 of the 102 World Series played between these two leagues from 1903 to 2006.
