The Aymara or Aimara people are an indigenous people in the Andes and Altiplano regions of South America; about 2.3 million live in northwest Argentina, Bolivia, Chile, and Peru. Their ancestors lived in the region for many centuries before becoming a subject people of the Inca in the late 15th or early 16th century, and later of the Spanish in the 16th century. With the Spanish American wars of independence (1810–1825), the Aymaras became subjects of the new nations of Bolivia and Peru. After the War of the Pacific (1879–1883), Chile annexed territory with Aymara population.
