The Inca Empire, also known as the Incan Empire and the Inka Empire, and at the time known as the Realm of the Four Parts, was the largest empire in pre-Columbian America. 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. The Spanish began the conquest of the Inca Empire in 1532 and its last stronghold was conquered in 1572.
