Cuismancu

Cuismancu, or Guzmango, was a kingdom in the Cajamarca highlands of northern Peru. Its hilltop centres included Tantarica, overlooking a route from the mountains to the coast.

In the fifteenth century a Guzmango Capac conquered Huamachuco and allied with Minchancaman of Chimor. The alliance failed against the Incas: after building the Incahuasi fortress around 1453, their generals defeated the confederates. The ruler Cuismanco fell defending Cajamarca around 1460, and his kingdom became an Inca province and a base for the later conquest of Chimor.
