About Major League Soccer (MLS)
The Major League Soccer (MLS) is the highest-level professional soccer league in the United States, operated by the U.S. Soccer Federation. Comprising 27 American teams and 3 Canadian teams, MLS runs a season from March to December, with each team playing 34 regular-season matches. The regular-season champion earns the Supporters' Shield, while the playoff winner claims the MLS Cup.

League History
Established in 1993, the league began play in 1996. Unlike traditional leagues with independently operated clubs, MLS employs a single-entity structure, where all teams are owned and controlled by the league's investors. As a closed membership league, MLS is one of the world’s few top-tier soccer competitions without a promotion-relegation system.
The inaugural 1996 season featured 10 teams, including the Columbus Crew, D.C. United, and New England Revolution, with D.C. United claiming the first MLS Cup. In 1998, Miami Fusion and the Chicago Fire joined the league. However, due to financial struggles and limited public interest, Tampa Bay Mutiny and Miami Fusion were dissolved in 2002. A pivotal moment came in 2007 with the introduction of the Designated Player Rule, which allowed clubs to sign high-profile stars like David Beckham.
From 2010 onward, MLS entered a decade of rapid expansion and stability, welcoming new teams such as Seattle Sounders, Portland Timbers, Vancouver Whitecaps, and Montreal Impact. World-class players like Thierry Henry, Kaká, and Zlatan Ibrahimović leveraged the Designated Player Rule to join the league. On December 8, 2024, Los Angeles Galaxy defeated New York Red Bulls 2:1 in the MLS Cup final, securing their 6th league title in club history.

Champions Teams
As of January 2025, Los Angeles Galaxy leads all clubs with 6 MLS Cup championships, followed by D.C. United with 4 titles.
