Great Incan Empire

From 1438 to 1533, the Incas used a variety of methods, from conquest to peaceful assimilation, to incorporate a large portion of western South America, centered on the Andean mountain ranges, including, besides Peru, large parts of modern Ecuador, western and south central Bolivia, northwest Argentina, north and central Chile, and a small part of southern Colombia into a state comparable to the historical empires of Eurasia. The official language of the empire was Quechua, although hundreds of local languages and dialects of Quechua were spoken. Many local forms of worship persisted in the empire, most of them concerning local sacred Huacas, but the Inca leadership encouraged the worship of Inti—their sun god—and imposed its sovereignty above other cults such as that of Pachamama.[4] The Incas considered their king, the Sapa Inca, to be the "son of the sun."
