After the Battle of Cepeda in February 1820, Irigoyen was named Governor-Mayor of Buenos Aires (9 to 11 February), but because of the dissolution of the Directorate and the formation of provincial governments, he was posted as provisional governor of the newly created Buenos Aires Province until the assumption of Manuel de Sarratea.
