The Inca Empire was the largest empire in pre-Columbian America. The administrative, political, and military center of the empire was located in Cusco in modern-day Peru. The civilization arose from the highlands of Peru in the early 13th century and was conquered by the Spaniards led by Francisco Pizarro in 1532. The official language of the empire was Quechua, although hundreds of local languages and dialects of Quechua were spoken. Incans referred to their empire as Tawantinsuyu, which means “The Four United Provinces”. Incans considered their King, the Sapa Inca, the “child of the sun”.
