During colonial times in the 18th century, an important flux of emigrants from Spain populated Chile, mostly Basques, who vitalized the Chilean economy and rose rapidly in the social hierarchy and became the political elite that still dominates the country. An estimated 1.6 million (10%) to 3.2 million (20%) Chileans have a surname (one or both) of Basque origin. The Basques liked Chile because of its great similarity to their native land: similar geography, cool climate, and the presence of fruits, seafood, and wine.
