The
Dayak or
Dyak or
Dayuh are the native people of
Borneo. It is a loose term for over 200 riverine and hill-dwelling ethnic subgroups, located principally in the interior of Borneo, each with its own dialect, customs, laws, territory and culture, although common distinguishing traits are readily identifiable.
Dayak languages are categorised as part of the
Austronesian languages in Asia. The Dayak were
animist in belief; however many converted to Islam and since the 19th century, mass conversion to Christianity.
