answer: national league, american league
answer type: Baseball League.
auxiliary information: Major League Baseball is a professional baseball organization that is the oldest of the four major professional sports leagues in the United States and Canada. A total of 30 teams now play in the American League and National League, which operated as separate legal entities from 1901 and 1876 respectively. In 2000, the leagues merged into a single organization led by the Commissioner of Baseball. The organization also oversees minor league baseball leagues, which comprise about 240 teams affiliated with the major-league clubs. With the World Baseball Softball Confederation, the league manages the international World Baseball Classic tournament. Baseball's first professional team was founded in Cincinnati in 1869. The first few decades of professional baseball were characterized by rivalries between leagues and by players who often jumped from one team or league to another. The period before 1920 in baseball was known as the dead-ball era; players rarely hit home runs during this time. Baseball survived a game-throwing incident known as the Black Sox Scandal in the 1919 World Series.
