Learn about the 1855-1856 uprising of the Santal tribe against the East India Company and the zamindari system in Jharkhand. Find out the causes, leaders, events, and outcomes of the rebellion. The Santhal Rebellion, also known as Santhal Hool, was a revolt by the Santhal tribal people against the British East India Company’s oppressive zamindari system in Bengal Presidency. The rebellion took place on 30 June 1855 and was led by four Murmu Brothers – Sidhu, Kanhu, Chand, and Bhairav. On the evening of 30th June 1855, over 10,000 Santhal men and women assembled at the Bhognadih village, located in the Sahibganj district of present-day Jharkhand, and pledged to rise against the exploitative rule of foreigners. This dramatic event marked the beginning of a turbulent year-long armed uprising (Hool) in the Rajmahal hills of Eastern India and surrounding regions by the Santhal tribe. The Santhal Rebellion (1855-1856), also known as the Santhal Hul, was one of the most significant tribal uprisings against British rule in India. Led by Sidhu and Kanhu Murmu, it originated in the Santhal Parganas, an area now part of modern-day Jharkhand.
