The earliest European immigrants were Spanish colonisers who arrived in the 16th century. The Amerindian population of central Chile was absorbed into the Spanish settler population in the beginning of the colonial period to form the large mestizo population that exists in Chile today; mestizos create modern middle and lower classes. In the 18th and 19th centuries, many Basques came to Chile where they integrated into the existing elites of Castilian origin. Postcolonial Chile was never a particularly attractive destination for migrants, owing to its remoteness and distance from Europe. Europeans preferred to stay in countries closer to their homelands instead of taking the long journey through the Straits of Magellan or crossing the Andes. European migration did not result in a significant change in the ethnic composition of Chile, except in the region of Magellan. Spaniards were the only major European migrant group to Chile, and there was never large-scale immigration such as that to Argentina or Brazil. Between 1851 and 1924, Chile only received 0.5% of European immigration to Latin America, compared to 46% to Argentina, 33% to Brazil, 14% to Cuba, and 4% to Uruguay. However, it is undeniable that immigrants have played a significant role in Chilean society.
