The Spanish colonization began in 1512. Argentina rose as the successor state of the Viceroyalty of the Río de la Plata, a Spanish overseas colony founded in 1776. The declaration and fight for independence (1810–1818) was followed by an extended civil war that lasted until 1861, which ended with the country's reorganization as a federation of provinces with Buenos Aires as its capital city. During the last two thirds of the 20th century Argentina faced several military coups and political instability, along with periodic economic crisis that restrained its full development.
Argentina is derived from the Latin argentum ("silver"). La Plata Basin does not have any sources of silver, but the first Spanish conquerors arrived in the area following rumors of the existence of silver mountains, hence the name.
