The Law 1420 of General Common Education of Argentina was a landmark national law that dictated public, compulsory, free, and secular education. It was passed in 1884 during the administration of President Julio Argentino Roca, after a number of similar laws of provincial scope and the conclusions of the Pedagogical Congress of 1882. This law established the mandatory primary education for all children from 6 to 14 years old. It ensured that all children would have access to a nearby school and that they would acquire important knowledge for their formation. It also established its gratuity and secularism.
