The only testimony comes from the first conquistadores who collected the natives’ tales. Successors, among others, to brilliant civilizations preceding them, the Incas were originally a small tribe from the Quechua region on the bank of Lake Titicaca, between Peru and Bolivia. They are part of a confederation of several groups, occupying at first a subordinate rank. The confederation relied on two clans, the Hanan detaining political power, and the Hurin, the military power of which the Incas were part of. This shared power explains the Inca group’s rise to power by force. It is only in during the mid-14th century that the Incas create a state bearing their name. Cuzco was the Inca capital for a long time, being the crossroads of the trans-Andean economical axis. It died down when economical activity turned towards Lima.
