The Santhal rebellion (sometimes referred to as the Sonthal rebellion), commonly known as Santhal Hool, was a native rebellion in present-day Jharkhand, in eastern India against both the British colonial authority and zamindari system by the Santhal people. It started on June 30, 1855 and on November 10, 1855 martial law was proclaimed which lasted until January 3, 1856 when martial law was suspended and the movement was brutally ended by troops loyal to the British.
