July 9 is Argentina’s Independence Day, celebrates the declaration of independence of the United Provinces of South America by the Congress of Tucumán in 1816.
Written history began with the arrival of Spanish chroniclers in the expedition of Juan Díaz de Solís in 1516 to the Río de la Plata, which marks the beginning of Spanish domination in this region.
In 1776 the Spanish Crown established the Viceroyalty of the Río de la Plata, an umbrella of territories from which, with the Revolution of May 1810, began a process of gradual formation of several independent states, including one called the United Provinces of Río de la Plata. With the declaration of independence on July 9, 1816 and the military defeat of the Spanish Empire in 1824, a federal state was formed in 1853-1861, known today as the Republic of Argentina.
Argentina, officially the Argentine Republic, is a federal republic in the southern portion of South America. Sharing the bulk of the Southern Cone with its neighbor Chile to the west, the country is also bordered by Bolivia and Paraguay to the north, Brazil to the northeast, Uruguay and the South Atlantic Ocean to the east, and the Drake Passage to the south. Argentina is the eighth-largest country in the world, the second largest in Latin America, and the largest Spanish-speaking one.
