Pratapgarh was an estate (taluqdari) of Oudh, British India.[1] The rulers of the estate were originally ruling from a place known as Taroul or Tiroul near Allahabad. The ancestor of the family was Babu Sujan Shah, son of Raja Sangram Shah of Tiroul.[2] Later a descendant, Babu Pratap Singh (1628–1683) came to the region known as Rampur and built a fort, and gave the city its current name, Pratapgarh.
