Paraná, Entre Ríos
Perón began his military career in an Infantry post in Paraná, Entre Ríos. He went on to command the post, and in this capacity mediated a prolonged labour conflict in 1920 at "La Forestal", then a leading firm in forestry in Argentina. He earned instructor's credentials at the Superior War School, and in 1929 was appointed to the Army General Staff Headquarters. Perón married his first wife, Aurelia Tizón ("Potota", as Perón fondly called her), on 5 January 1929.
