The Inca civilization began as a tribe in the Cuzco area of Peru, where the legendary first Sapa Inca, Manco Capac founded the Kingdom of Cuzco around 1200. Under the leadership of the descendants of Manco Capac, the Inca state grew to absorb other Andean communities. In 1442, the Incas began a far-reaching expansion under the command of Patchacuti. He founded the Inca Empire (Tawantinsuyu), which became the largest empire in pre-Columbian America.

The empire was split by a civil war to decide who would be Inca Hanan and who would be Inca Hurin (Hanan and Hurin represent the families of the higher parts of the city (Hanan) and those of the lower parts (Hurin) it is believed that one of the brothers was from Hanan Cuzco and the other from Hurin Cuzco as they were part of the family of their mothers), which pitted the brothers Huascar and Atahualpa against each other. In 1533, Spanish Conquistadores led by Francisco Pizarro, took advantage of this situation and conquered much of the existing Inca territory. In succeeding years, the invaders consolidated power over the whole Andean region, repressing successive Inca resistance and culminating in the establishment of the Viceroyalty of Perú in 1542. The militant phase of Inca liberation movements ended with the fall of resistance in Vilcabamba during 1573. Though indigenous sovereignty was lost, Inca cultural traditions remain strong among surviving indigenous descendants, such as the Quechua and Aymara people.

Inca in "Vilcabamba"Edit

On the eve the United States and Canada's final uprising against the Krolp, President Harris Moffatt III's Secretary of Alien Affairs shared with Moffatt the history of the Inca and their last refuge of Vilcabamba. Moffatt recalled that information during the uprising. He sympathized with the Inca, and knew that they'd sympathize with him, for all the good that would do.

Inca in "Eyewear"Edit

While in some timelines, including the one inhabited by Estevánico, the Incan Empire was conquered by Spanish Conquistador Francisco Pizarro, there were others where the Inca survived, drove back Pizarro, and eventually become a dominant global power. In at least one of these, the Inca were at war with the descendants of the unconquered Aztec Empire by the 23rd Century, a war which crossed timelines and time itself.

Estevánico learned of the Inca indirectly from the time-traveler Esperanza after the failure of the Pánfilo de Narváez expedition. Estevánico was bitterly amused by the fact that the trip north had been an utter waste, and that a rich empire existed in the south.
