Explanation:The Inca Empire (Quechua: Tawantinsuyu, lit. "four parts together"[4]), also known as the Incan Empire and the Inka Empire, was the largest empire in pre-Columbian America.[5] The administrative, political and military center of the empire was in the city of Cusco. The Inca civilization arose from the Peruvian highlands sometime in the early 13th century. Its last stronghold was conquered by the Spanish in 1572.

From 1438 to 1533, the Incas incorporated a large portion of western South America, centered on the Andean Mountains, using conquest and peaceful assimilation, among other methods. At its largest, the empire joined Peru, western Ecuador, western and south central Bolivia, northwest Argentina, a large portion of what is today Chile, and the southwesternmost tip of Colombia into a state comparable to the historical empires of Eurasia. Its official language was Quechua.[6] Many local forms of worship persisted in the empire, most of them concerning local sacred Huacas, but the Inca leadership encouraged the sun worship of Inti – their sun god – and imposed its sovereignty above other cults such as that of Pachamama.[7] The Incas considered their king, the Sapa Inca, to be the "son of the sun."[8
