Quechua has been spoken in the Andes region of South America for a long time, even before the Inca Empire. After the Spanish conquest in the 16th century, Quechua continued to be used widely to communicate between the Spanish and indigenous peoples. However, over time its prestige declined and it became restricted to rural areas. Now there are approximately 6,500 native Quechua speakers worldwide, located primarily in Peru. The language is endangered because some believe Spanish signifies education and culture, while Quechua is seen as a language for uneducated people.
