Inca Empire
1438–1533 empire in South America
The Inca Empire, officially known as the Realm of the Four Parts (Quechua: Tawantinsuyu pronounced [taˈwantiŋ ˈsuju], lit. 'land of 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 civilisation rose from the Peruvian highlands sometime in the early 13th century. The Portuguese explorer Aleixo Garcia was the first European to reach the Inca Empire in 1524. Later, in 1532, the Spanish began the conquest of the Inca Empire, and by 1572 the last Inca state was fully conquered.
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 modern-day Peru with what are now western Ecuador, western and south-central Bolivia, northwest Argentina, the southwesternmost tip of Colombia and a large portion of modern-day Chile, forming a state comparable to the historical empires of Eurasia. Its official language was Quechua.
The Inca Empire was unique in that it lacked many of the features associated with civilization in the Old World. The 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.
This brief starts where responsible research should: with the source description of “Inca Empire” as 1438–1533 empire in South America. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the history & society register because the source frames it as 1438–1533 empire in South America. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Contemporary correspondence, administrative files and participant testimony can test how later narratives organized the event or institution. The source revision retrieved here is dated Sep 21, 2026. The linked authority identifier is Q28573. The Library of Congress control number is sh85064726. Authority coordinates are -13.517, -71.967. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1524, 1532, 1572 and 1438.
Institutional narratives can privilege the records that survived while minimizing voices that were never formally collected. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
