The iraca, sometimes spelled iraka,[1][2] was the ruler and high priest of Sugamuxi in the confederation of the Muisca who inhabited the Altiplano Cundiboyacense; the central highlands of the Colombian Andes. Iraca can also refer to the Iraka Valley over which they ruled.[1][2][3] Important scholars who wrote about the iraca were Lucas Fernández de Piedrahita, Alexander von Humboldt and Ezequiel Uricoechea.
