Kambiwa

The Kambiwá, also called Cambiuá, are an Indigenous people of the Pernambuco sertão, established around Inajá, Ibimirim and Floresta. They once held the Serra Negra hills between Ibimirim and Petrolândia, still counted as their sacred territory, until pressure from white colonists drove them out; their own language survives only in short word lists and is treated as unclassified and extinct.
