The Acta de la Declaración de la Independencia Argentina signed, the newly formed congress couldn’t reach agreement on a form of government. They appointed a supreme director, but many delegates preferred a constitutional monarchy. Others wanted a centralized republican system, still others a federal system. Unable to reach consensus, the opposing beliefs eventually led to a civil war in 1819.
Taking power, Juan Manuel de Rosas, ruled from 1829 to 1852 while acting as a caretaker of the external relations of the whole country, who lacked any other form of federal government. Acknowledged as a tyrant, Rosas was overthrown by a revolution led by General Justo José de Urquiza under whom Argentine national unity was established, and a constitution promulgated in 1853.
