The Santhal Revolt (also known as Santhal Hul) of 1855-1856 was led by four Santhal brothers: Sidhu Murmu, Kanhu Murmu, Chand Murmu, and Bhairav Murmu. Among them, Sidhu and Kanhu were the principal leaders who declared themselves to be communicating with God and leading the rebellion against the oppressive landlords, moneylenders, and the British East India Company officials. "Siddho" in the option refers to Sidhu Murmu.
