The Uruguay Primera Division, also known as the Uruguayan Football Championship, is the top professional soccer league in Uruguay. It was established in 1900, making it one of the oldest leagues in South America. The league consists of 16 teams, with each team playing a total of 30 matches in a season. The most successful teams in the league's history are Club Nacional de Football and Club Atlético Peñarol, who have dominated Uruguayan football, winning a combined total of 96 league titles. An interesting fact is that the league has a unique format where the top two teams from the previous season's table qualify for the Copa Libertadores, while the team with the worst record is relegated to the second division.
