Anthropologist Gordon McEwan wrote that the Incas were able to construct 'one of the greatest imperial states in human history' without the use of the wheel, draft animals, knowledge of iron or steel, or even a system of writing. The Inca Empire was unique in that it lacked many of the features associated with civilization in the Old World.
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. The Spanish began the conquest of the Inca Empire in 1532 and its last stronghold was conquered in 1572.įrom 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. The Inca civilization arose from the Peruvian highlands sometime in the early 13th century. The administrative, political and military center of the empire was in the city of Cusco. The Inca Empire, also known as 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.
