1912 Argentine Primera División

Two tournaments were held at the same time, due to the establishment of Federación Argentina de Football (FAF), a dissident association which organised its own championship.

Recently promoted teams Porteño and Estudiantes (LP) joined the new league, among other clubs.

This tournament was formed by 3 dissident teams from the Asociación Argentina (AAF): Estudiantes de La Plata, Gimnasia y Esgrima (BA) and Porteño, plus the 4 teams promoted from the second division: Argentino de Quilmes, Atlanta, Independiente and Kimberley.

[2] Independiente and Porteño finished level on points at the top of the table, necessitating a championship playoff.

The game was suspended at 87' after the Independiente players abandoned the pitch in protest at a disallowed goal by referee Carlos Aertz.
