The term "Ulgulan" or "the Great Tumult" refers to a significant tribal uprising in the history of India.

The rebellion (ulgulan) of the Munda tribesmen, led by Birsa Munda, occurred during 1899-1900. For over thirty years the Munda sardars had been struggling against the destruction of their system of common land holdings by the intrusion of jagirdar, thikadar (revenue farmers) and merchant moneylenders. Birsa Munda led the Munda tribe in a rebellion against the British colonial rule and the feudal system imposed by them.
