The Spanish navigators Juan Díaz de Solís and Sebastian Cabot visited the territory that is now Argentina in 15, respectively.
The Spanish Empire subordinated the economic potential of the Argentine territory to the immediate wealth of the silver and gold mines in Bolivia and Peru, and as such it became part of the Viceroyalty of Peru until the creation of the Viceroyalty of the Río de la Plata in 1776 with Buenos Aires as its capital.
Although "Argentina" was already in common usage by the 18th century, the country was formally named "Viceroyalty of the Río de la Plata" by the Spanish Empire, and "United Provinces of the Río de la Plata" after independence.
The 1826 constitution included the first use of the name "Argentine Republic" in legal documents.
One year later General Martín Miguel de Güemes stopped royalists on the north, and General José de San Martín took an army across the Andes and secured the independence of Chile; then he led the fight to the Spanish stronghold of Lima and proclaimed the independence of Peru.
In English the name "Argentina" probably comes from the Spanish language, however the naming itself is not Spanish, but Italian.Starting with Julio Argentino Roca in 1880, ten consecutive federal governments emphasized liberal economic policies.The massive wave of European immigration they promoted—second only to the United States'—led to a near-reinvention of Argentine society and economy that by 1908 had placed the country as the seventh wealthiest from 1870 to 1910 Argentina's wheat exports went from 100,000 to 2,500,000 t (110,000 to 2,760,000 short tons) per year, while frozen beef exports increased from 25,000 to 365,000 t (28,000 to 402,000 short tons) per year, In 1865, Argentina was already one of the top 25 nations by per capita income.The country thereafter enjoyed relative peace and stability, with massive waves of European immigration radically reshaping its cultural and demographic outlook.The almost-unparalleled increase in prosperity led to Argentina becoming the seventh wealthiest developed nation in the world by the early 20th century.
