Argentina Declares Independence from Spain
On July 9, 1816, delegates gathered in the city of Tucumán formally declared the independence of the United Provinces of the Río de la Plata from the Spanish Crown — the birth of modern Argentina. The declaration came six years after the May Revolution of 1810, after years of war and political turbulence across South America. The Congress of Tucumán voted unanimously to sever ties with Spain, becoming one of the most consequential moments in Latin American history. The country that emerged would grow into the eighth-largest nation on earth. Argentina still celebrates July 9 as its Independence Day, with the original proclamation reading aloud in the historic Casa Histórica de la Independencia.
