Why is there an American League and a National League in baseball?

Answer 1

The first professional Baseball organization was formed in 1876 as a sports business. The people who formed this organization called it the National League. In 1901 another baseball organization was formed and called themselves the American League. Soon after the two leagues recognized each other as legitimate professional baseball organizations and created what we now refer to as Major League Baseball. They agreed to the same rules of play and also to hold a end of the season championship called the World Series. Much later on changes were made to the American League. As example the American League instituted the designated hitter "rule". In 1977 both leagues agreed to inter league play. Other changes such as the height of the pitcher's mound were agreed to by both leagues.
