Historical and modern distribution

When Europeans first arrived in the western Amazon Basin in significant number in the late 17th and early 18th century, Omagua was spoken by approximately 100,000 individuals in two major areas: along the Amazon River proper, between the mouths of the Napo River and Jutaí River, and in the vicinity of the Aguarico River, a tributary of the upper Napo River. At this time, then, Omagua speakers lived in regions corresponding to modern eastern Peruvian Amazonia, western Brazilian Amazonia, and eastern Ecuadoran Amazonia.

These Omagua populations were decimated by disease, Portuguese slave raids, and conflicts with Spanish colonial authorities during the early 18th century, leaving them drastically reduced. As of 2011, Omagua was spoken by "fewer than ten elderly individuals" in Peru,^[5] and by a number of semi-speakers near the towns of Coari and Tefé in Brazil, where the language is known as Cambeba (Grenand and Grenand 1997).

Genesis of Omagua

Comparative work by Cabral (1996) demonstrated that Omagua (and its sister language Cocama) exhibit significant grammatical restructuring effects due to intense language contact between a Tupí-Guaraní language and speakers of one or more non-Tupí-Guaraní languages. Rodrigues and Cabral (2003) further suggest that Cocama (and by extension, Omagua) could be considered the outcomes of rapid creolization. Cabral (1996) argued that this language contact transpired in the late 17th century in Jesuit mission settlements, while Michael (2014)^[3] argues that the language contact situation responsible for the genesis of Omagua and Cocama transpired during the Pre-Columbian period.
