The 'Kiratas' (
Sanskrit: किरात) mentioned in early
Hindu texts are the tribals or
Adivasi of the land. They are mentioned along with
Cinas (Chinese). Kiratas are believed to be of
Tibeto-Burman origin. Kiratas have been identified as the present day
Rai,
Limbu and
Sunuwar of Nepal. Ghatotkacha of
Mahabharata fame (Son of Bhima) was a Kirata Chieftain.
In
Yoga Vasistha 1.15.5
Rama speaks of ''kirAteneva vAgurA'', "a trap [laid] by Kiratas", so about BCE Xth Century, they were thought of as jungle trappers, the ones who dug pits to capture roving deer. The same text also speaks of King Suraghu, the head of the Kiratas who is a friend of the Persian King, Parigha.
The most famous Kiratas in
Hinduism are the Kiratra avatar of
Shiva,
Lord Buddha and sage
Valmiki, writer of the
Ramayana.
