He is mostly known in the Indian subcontinent for the folk tales which focus on his wit. Birbal was appointed by Akbar as a minister "mantri" and was a poet and singer in around 1556-1562. He had a close association with Emperor Akbar and was one of his most important courtiers, part of a group called the navaratnas (nine jewels) of Akbar. In 1586, Birbal led an army to crush an unrest in the north-west Indian subcontinent where he was killed along with many troops in an ambush by the rebel tribe. He was the only Hindu to adopt Din-i Ilahi, the religion founded by Akbar.)
