The 1920 South American Championship (, ) was the fourth international association football championship for members of the Confederación Sudamericana de Fútbol (CONMEBOL). Hosted by Chile, the competition ran from 11–26 September 1920 and was contested by the national teams of Argentina, Brazil, Chile and Uruguay.
During the competition, Brazil lost heavily to Uruguay 6–0. It would remain the team's largest defeat until it was equalled by a 7–1 loss to Germany at the 2014 FIFA World Cup.
In the final round of matches of the round-robin tournament, Uruguay defeated 2–1 to win the championships for the third time.
Background
In 1910, the Asociación del Fútbol Argentino (AFA) organised a tournament to mark the 100th anniversary of the May Revolution. The Copa Centenario Revolución de Mayo was contested by the national teams of Argentina, Chile and Uruguay and is considered to be a precursor to the South American Championship. Six years later, the AFA organised a second tournament, this time to celebrate the centenary of the Argentine Declaration of Independence. Alongside the three who had contested the Copa Centenario Revolución de Mayo, Brazil were invited to compete and the South American Championship was born. During the competition, the four associations of the competing teams met on 9 July 1916 and founded the Confederación Sudamericana de Fútbol (CONMEBOL).
Brazil were the defending champions having won the 1919 edition after defeating Uruguay 1–0 after extra time in the championship play-off. Uruguay were the most successful team in the history of the competition having won the first two editions.
Format
The tournament was played as a round-robin where each team would play all of the others once. The winner would be decided by the total number of points obtained across all matches played.
