Early history

The earliest predecessor to the American League was the
Northwestern League The Northwestern League was a sports league that operated in the Central United States during the early years of professional baseball for five seasons: 1879, 1883–1884, and 1886–1887. After the 1887 season, the league was replaced by the We ...

Transition to a major league

Johnson and his associates Comiskey and Mack thought that they could make a move at becoming a major league by the turn of the 20th century, but knew that they would face the same struggles as the failed American Association. During a meeting of Western League owners at

's Great Northern Hotel on October 11, 1899, the league's name was changed to the American League of Professional Baseball Clubs. At the time of the name change, the National League was struggling in attendance, while in comparison, the American League had a zero tolerance for foul language and behavior, bolstering attendance because of its image. In ''The Arrival of the American League'', author Warren N. Wilbert described the National League as having a

Hitting success

Before the 1920s, pitching dominated both leagues. In 1920, both leagues adopted new rules against defacing baseballs. Led by Babe Ruth, hitters in the American League dominated the pitching competition. Attendance was mostly even with the National League through the 1920s. From 1927 to 1930, the National League beat the American League in attendance for the first time since the American League became a major league. Through the 1930s, high scoring continued in the American League, unlike the National League where runs were becoming scarce. In every year from 1931 through 1942, the American League outscored the National League. From the same 12-year time period, the American League led in attendance six time while the National League led six times, despite the scoring dependency.

Writer Steve Treder from ''The Hardball Times'' noted that the fact that the American League employed fewer African Americans led to a discrepancy in talent, giving the National League the upper hand. Over the time period of racial desegregation in baseball, the American League had better attendance than the National League for most of the seasons. Starting in 1956, the National League began a 33-year streak of attendance superiority over the American League. Treder again asserted that the American League failed to desegregate their league as fast and eagerly as the National League, however, he states that by the 1960s the American League started to catch-up.
