The American League (AL) is one of two main groups of teams in Major League Baseball (MLB). It is based in the United States and Canada. The American League is often called the Junior Circuit. This is because it became a major league in 1901, which was 25 years after the National League (the Senior Circuit) was formed.
Since 1903, the American League champion team has played against the National League champion in the World Series. This has happened almost every year. The only times it didn't happen were in 1904 and 1994. Through 2023, American League teams have won 68 of the 119 World Series played. The New York Yankees have won the most World Series titles (27) and American League titles (40).
For many years, teams only played against others in their own league during the regular season. Also, each league had its own umpires. This led to slightly different ways of playing. The American League was seen as less "traditional." For example, in 1973, the AL started using the designated hitter rule. This rule lets a player bat instead of the pitcher. Over time, these differences have become much smaller. This is because players can now move between leagues more easily. Also, teams from different leagues play each other during the regular season.
Even though both leagues agreed to have a commissioner in 1920, they stayed separate businesses. They had their own presidents. But after the 1999 season, the American League officially joined with the National League. Now, Major League Baseball runs both leagues together.

How did the American League start?
The American League began as a smaller league called the Western League. This league existed from 1885 to 1899. Its teams were mostly in the Great Lakes area. In 1900, the league changed its name to the American League. The next year, it became a major league. It competed with the older National League. This happened after the National League removed four teams in 1899.
The Western League struggled in its early years. But in 1894, Ban Johnson became its president. Johnson worked hard to make the league a major one. The decision to change the name to the American League happened at a meeting in Milwaukee, Wisconsin. In March 1904, Johnson moved the league's main office from Chicago to New York.
Babe Ruth, one of baseball's greatest hitters, played most of his career in the American League. He played for the Boston Red Sox and the New York Yankees. From 1973 to 2022, the American League had a special rule: the designated hitter. This rule lets a team use a player to bat instead of the pitcher. The National League did not use this rule until 2022.

In 1969, both the American League and National League were split into East and West divisions. This led to a playoff series to decide the league champion. In 1994, the league changed again. It was divided into three divisions: East, West, and Central. A new playoff round was added, called the American League Division Series. The best second-place team could also make the playoffs as a "wild-card" team.
In 1998, two new teams joined MLB. The Tampa Bay Devil Rays joined the American League. The Arizona Diamondbacks joined the National League. This meant each league had 15 teams. To make things even, the Milwaukee Brewers moved from the American League to the National League. The Detroit Tigers also moved within the American League. In 2013, the Houston Astros moved from the National League to the American League. Now, both leagues have 15 teams.
Playing against the National League
For 96 years, American League teams only played National League teams in special exhibition games or the World Series. But starting in 1997, they began playing each other during the regular season. These games count in the standings. Until 2022, the designated hitter rule was only used when an American League team was playing at home. In 2022, the designated hitter rule became used by all teams in both leagues.
In 2000, the American League officially joined with Major League Baseball. This meant MLB became one big organization with two parts, still called leagues. This change did not affect how the games were played or scheduled.
