Bhopal State (pronounced bɦoːpaːl) was an Islamic principality founded in the beginning of 18th-century India by the Afghan Mughal noble Dost Muhammad Khan. It was a tributary state during 18th century, a princely salute state with 19-gun salute in a subsidiary alliance with British India from 1818 to 1947, and an independent state from 1947 to 1949. Islamnagar was founded and served as the State's first capital, which was later shifted to the city of Bhopal.
The state was founded in 1707 CE by Dost Mohammad Khan, a Pashtun soldier in the Mughal army, who became a mercenary after the Emperor Aurangzeb's death and annexed several territories to his fiefdom. It came under the suzerainty of the Nizam of Hyderabad in 1723 shortly after its foundation. In 1737, Marathas defeated the Mughals and the Nawab of Bhopal in the Battle of Bhopal, and started collecting tribute from the state. After the defeat of the Marathas in the Third Anglo-Maratha War, Bhopal became a British princely state in 1818. Bhopal State had an area of 6,902 sq. miles in pre-independence India, with a Muslim leadership, first being Hyderabad State. The state was merged into the Union of India in 1949 as Bhopal. In 1901 the state had a population of 665,961 and an average revenue of Rs. 25,00,000.
Bhopal state was unique for a continuous lineage of four female Nawabs who ruled its throne for over a century between 1819 and 1926. During this period, the state was noteworthy for its immense contributions to the development of Islamic religious activities, cultural reform and educational efforts which caused a growing appreciation for its rulers in Indian political circles. Some of the Islamic revival activities of the Bhopal state were met with disapproval by the British authorities.
The State of Bhopal was established by Dost Mohammad Khan (1672–1728), a pashtun soldier in the Mughal Army. After the death of the emperor Aurangzeb, Khan started providing mercenary services to several local chieftains in the politically unstable Malwa region.
