Babu Kunwar Singh of Jagdishpur and his army, as well as countless other persons from Bihar, contributed to the India's First War of Independence (1857), also called the Sepoy Mutiny by some historians. Babu Kunwar Singh (1777–1858) one of the leaders of the Indian uprising of 1857 belonged to a royal Rajput house of Jagdispur, currently a part of Bhojpur district of Bihar. By that time Bihar had many feudal estates or zamindars. Most notably Tekari Raj, Raj Darbhanga, Bettiah Raj, Hathwa Raj, Kharagpur Raj and Banaili Estate. At the age of 80 years, during India's First War of Independence, he actively led a select band of armed soldiers against the troops under the command of the East India Company, and also recorded victories in many battles.
