The Quechua are the most widespread indigenous group of the Americas, with some ten million spread across Peru, Bolivia, and Ecuador (there known as Quichua), and smaller numbers in Argentina, Chile, and Colombia (there known as Ingano). Quechua speakers outnumber speakers of all other indigenous languages in South America combined, due in part to Quechua's status as the administrative language of the Inca Empire (Tawantisuyu), which at the turn of the16th century covered much of western South America.
