All about the ancient tribes
Quechua is the only Inca language that has been preserved to this day.
The Quechua language was the official language of the Inca Empire, despite the fact that it controlled a vast territory and had many provinces populated by a variety of ethnic groups, each of which spoke their own language. Once a province was conquered, the king would send teachers known as Amautas to teach the Quechua language to the local population.
Quechua did not begin with the Incas, had been a lingua franca in numerous locations before the Inca expansions, was diverse before the advent of the Incas, and it was not the native or original language of the Incas. All of these facts indicate that Quechua did not originate with the Incas.
Etymology. Although they probably only numbered between 15,000 and 40,000 in total, the Incas ruled over a population of over 10 million people. This is a relatively small fraction of the entire population of the Inca Empire. The Spanish used the phrase as an ethnic term referring to all subjects of the empire rather than just the ruling elite. The term is transliterated as Inca in Spanish.
Because Quechua was the language used by the Incas, the city of Cusco adopted it as the official language of the region about the year 1400.As a result of the expansion of the Inca empire into other regions of Peru, the Quechua language began to be spoken by a greater number of people throughout the country.The Inca Empire was exceptionally well structured, which contributed to the empire’s growth and, eventually, its success up to the year 1533.
