Jaunpur Sultanate

The Jaunpur Sultanate (Persian: سلطنت جونپور) was an Indian Muslim state which ruled over much of what is now the states of Uttar Pradesh and Bihar between 1394 and 1494. It was founded in 1394 by Khwajah-i-Jahan Malik Sarwar, an eunuch slave and former wazir of Sultan Nasiruddin Muhammad Shah IV Tughluq, amidst the disintegration of the Delhi Sultanate's Tughlaq dynasty. Centred in Jaunpur, the Sultanate extended authority over a large part of the Ganges-Yamuna Doab. It reached its greatest height under the rule of Sultan Ibrahim Shah, who also vastly contributed to the development of Islamic education in the Sultanate. In 1494, Sultan Hussain Khan was defeated by the forces of the Afghan ruler Bahlul Lodi, Sultan of the Lodi dynasty of the Delhi Sultanate at Benares at which point Hussain fled to Kahalgaon in modern-day Bihar where the Sultan of Bengal assigned him a pargana. Here he was allowed to mint his own coins and was promised help from Bengal in recovering his kingdom. He died in 1505.
