The American League of Professional Baseball Clubs, known simply as the American League (AL), is one of two leagues that make up
Major League Baseball (MLB) in the
United States
The United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America. It consists of 50 states, a federal district, five major unincorporated territori ...

. It developed from the
Western League, a minor league based in the
Great Lakes states, which eventually aspired to
major league status. It is sometimes called the Junior Circuit because it claimed Major League status for the 1901 season, 25 years after the formation of the
National League (the "Senior Circuit").
At the end of every season, the American League champion plays in the
World Series against the National League champion; two seasons did not end in playing a World Series (1904, when the National League champion
New York Giants refused to play their AL counterpart, and 1994, when a
players' strike prevented the Series). Through 2021, American League teams have won 66 of the 117 World Series played since 1903, with 27 of those coming from the
New York Yankees alone. The New York Yankees have won 40 American League titles, the most in the league's history, followed by the
Philadelphia/Kansas City/Oakland Athletics (15) and the
Boston Red Sox

History
Originally a
minor league known as the
Western League, which existed from 1885 to 1899 with teams in mostly
Great Lakes states, the league changed its name to the American League for the 1900 season and the next year developed into a second major league as a competitor to the older
National League. This was prompted by the NL dropping four teams following the 1899 season after having absorbed its previous rival, the
American Association, which disbanded in 1891 after ten seasons.
In its early history of the late 1880s, the minor Western League struggled until 1894, when
Ban Johnson became the president of the league. Johnson pushed the league to rise to major league status, after the name change to the American League was decided in a league meeting in
Milwaukee, Wisconsin, at the former Republican Hotel. A historical marker is at the intersection of North Old World 3rd Street and West Kilbourn Avenue where the hotel once stood.
In March 1904, Johnson moved the league's headquarters from Chicago to New York.
Babe Ruth, noted as one of the most prolific hitters in
Major League Baseball history, spent the majority of his career in the American League with the
Boston Red Sox

and the
New York Yankees. The American League has one notable difference versus the rival
National League: in modern times since 1973, it has had the
designated hitter rule. Under the rule, a team may use a
batter in its
lineup who is not in the field defensively, replacing the
pitcher
In baseball, the pitcher is the player who throws ("pitches") the baseball from the pitcher's mound toward the catcher to begin each play, with the goal of retiring a batter, who attempts to either make contact with the pitched ball or draw ...
in the batting order, compared to the old rule that made it mandatory for the pitcher to bat. In the last two decades, the season schedule has allowed occasional interleague play. In 1969, the AL (and NL) were divided into East and West divisions, with a postseason playoff series for the pennant and the right to play in the World Series.
Until the late 1970s, league umpires working behind home plate wore large, balloon-style chest protectors worn outside the shirt or coat, while their colleagues in the National League wore chest protectors inside the shirt or coat. In 1977, new umpires (including
Steve Palermo
Stephen Michael Palermo (October 9, 1949 – May 14, 2017) was an umpire in Major League Baseball who worked in the American League from 1977 to 1991. His field career ended when he was shot in the back following his decision to intervene and ap ...
) had to wear the inside chest protector, although those on staff wearing the outside protector could continue to do so. Most umpires made the switch to the inside protector, led by
Don Denkinger in 1975 and
Jim Evans the next year, although several did not, including
Bill Haller
William Edward Haller (February 28, 1935 – August 20, 2022) was an American Major League Baseball umpire. Haller officiated 3,068 regular season games in the American League in 1961 and from 1963 to 1982. He also worked 15 American League Cha ...

In 1994, the league, along with the National League, reorganized again, this time into three divisions (East, West, and
Central) and added a third round to the playoffs in the form of the
American League Division Series, with the best second-place team advancing to the playoffs as a wild-card team, in addition to the three divisional champions. In 1998, the newly franchised

against its counterpart in the other league. The initial plan was to have three five-team divisions per league with inter-league play year-round—possibly as many as 30 interleague games per team each year.
For various reasons, it soon seemed more practical to have an even number of teams in both leagues. The
Milwaukee Brewers agreed to change leagues to become the National League's 16th team, moving from the AL Central to the NL Central. At the same time, the
Detroit Tigers were moved from the AL East to the AL Central, making room for the Devil Rays in the East. Even after expansion, the American League then continued with 14 teams. This situation changed again in 2013 when the
Houston Astros moved from the National League Central division to the American League West. The Astros had been in the NL for 51 years since beginning as an expansion team in 1962. Since their move, both leagues now consist of 15 teams.
Permanent interleague play
For the first 96 years, American League teams faced their National League counterparts only in exhibition games or in the World Series. Beginning in 1997, interleague games have been played during the regular season and count in the standings. As part of the agreement instituting interleague play, the designated-hitter rule was used only in games where the American League team is the home team, until the 2022 season, when the universal DH rule was implemented.
