"Ulgulan," or the Great Tumult, refers to Birsa Munda’s Revolt of 1899-1900, which aimed to establish Munda Raj and combat the exploitative practices of British colonialism and local zamindars in the Chotanagpur region of present-day Jharkhand. This uprising is significant as it reflects the broader tribal resistance against colonial oppression and the socio-economic grievances of indigenous communities, highlighting the intersection of tribal identity and anti-colonial sentiment. Birsa's movement not only challenged the existing power structures but also inspired subsequent struggles for rights and recognition among tribal populations in India.
