Cambeba people
（重定向自Omaguas）
The Cambeba people (also known as the Omagua, Umana, and Kambeba) are an indigenous people in Brazil's Amazon Basin, with territory extending into Peru. They speak the Omagua language. The Cambeba exist today in small numbers, but they were a populous, organized society in the late Pre-Columbian era. Their population suffered steep decline, mostly from infectious diseases, in the early years of the Columbian Exchange.
