Along with numerous nomadic tribespeople, two main indigenous groups existed in Argentina before the European arrival. In the northwest, near Bolivia and the Andes, was a people known as the Diaguita, while further south and to the east were the Guarani. Together the Diaguita and the Guarani constitute the origins of permanent agricultural civilization in Argentina, both developing the cultivation of maize. The Diaguita are also remembered for having successfully prevented the powerful Inca from expanding their empire into Argentina from what is now Bolivia.
It was perhaps a legacy of this successful resistance that enabled the native peoples of Argentina to carry on a prolonged campaign against colonization and rule by the Spanish. The first Spaniard to land in Argentina, Juan de Solis, was killed in 1516, and several attempts to found Buenos Aires were stymied by the local inhabitants. Inland cities were more successful, and it wasn't until the late 16th century that Buenos Aires was securely established.
Argentina's culture has been greatly affected by its immigrant population, mostly European. Their influence contributed to the demise of pre-Columbian cultures, resulting in the lack of a dominant indigenous population. The European immigrant groups each adopted different roles. The Basque and Irish controlled sheep rearing, the Germans and Italians established farms, and the British invested in developing the country's infra- structure.
More than one-third of the country's 32 million people live in Buenos Aires, the capital, which along with other urban areas accounts for almost 90% of the total population. The principal indigenous peoples are the Quechua of the northwest and the Mapuche in Patagonia. Other marginal groups include the Matacos and Tobas in the Chaco and other northeastern cities. There are strong Jewish and Anglo-Argentine communities throughout the country; small communities of Japanese, Chileans and Bolivians; and enclaves of Paraguayan and Uraguayan residents.
The universal language of Argentina is Spanish, but many natives and immigrants keep their mother tongues as a matter of pride.
