Chileans (Spanish: Chilenos, pronounced [tʃiˈlenos]) are an ethnic group and nation native to the country of Chile and its neighboring insular territories. Most Chileans share a common culture, history, ancestry and language. The overwhelming majority of Chileans are the product of varying degrees of admixture between white ethnic groups (predominantly Basques and Spaniards) with peoples indigenous to Chile's modern territory (predominantly Mapuche). Chile is a multilingual and multicultural society, but an overwhelming majority of Chileans have Spanish as their first language and either are Christians (mainly Catholic) or have a Christian cultural background. There is a relatively large irreligious minority.
However, many Chileans do not equate their nationality with ethnicity, but with citizenship and allegiance to Chile. This has resulted due to immigration to Chile throughout its history, and thus the term "Chilean" can now also include people identifying with the country whose connection may not be ethnic, but cultural, historical, legal, or residential. For most modern Chileans, several or all of these connections exist and are collectively the source of their Chilean identity.
