Highland farmers and guinea-pig herders of the Chimborazo and Bolívar basin south of Quito, organized as a confederation of chiefdoms (Cacha, Calpi, Punin, Guano, Licto, Sicalpa) that traded with, and by the late 15th century came under, the expanding Inca state.
Absorbed into Inca Collasuyu/Chinchaysuyu administration in the 15th century; devastated by disease and forced Quechuization under Spanish rule from the 1530s-1700s; Puruhá communities of Chimborazo Province rose under Fernando Daquilema in 1871 and remain a living indigenous people today.
