Omagua

1000 CE – 1700 CE (approx.)

A powerful riverine chiefdom on the upper Amazon whose dense villages amazed the first Spanish explorers in the 16th century.

Origins

The Omagua, a Tupi-Guarani-speaking people, settled along the Amazon, known locally as the Solimões, and its islands between the Napo and Juruá rivers. Their expansion along the river is dated archaeologically to around 1000.

Rule and society

Gaspar de Carvajal, who accompanied Francisco de Orellana's voyage down the Amazon in 1542, described the territory of a chief called Machiparo and densely populated villages lining the riverbanks. The Omagua farmed manioc and maize on the fertile floodplain, kept turtles in pens and traded goods along the river. They flattened the foreheads of infants as a mark of status. They were noted for fine painted pottery and cotton cloth.

Decline and legacy

Slave raids from Portuguese Brazil, epidemics and the missions of the Jesuit Samuel Fritz around 1700 broke up the chiefdom. Survivors moved upriver into Spanish territory, settling around San Joaquín de Omaguas in Peru. A few communities, also known as Cambeba, survive in Peru and Brazil.

Few sources survive for this state; details are uncertain.
