Calva
Calva was a Palta chiefdom in the Loja highlands of southern Ecuador. The Calvas held the valleys south of the Catamayo river, including Sabiango and Macará, and were among the strongest Palta chiefdoms.
The Palta chiefs resisted the armies of Tupac Inca Yupanqui, Inca ruler from 1471 to 1493, but their region was absorbed into the Inca Empire. The Spanish later overran it, and under colonial rule the Palta language and chiefly order disappeared within a few generations.
