A breakaway sultanate founded by Khwajah-i-Jahan Malik Sarwar, a former Tughlaq wazir, amid the Delhi Sultanate's collapse; it controlled much of the Ganges-Yamuna Doab (modern Uttar Pradesh/Bihar and southern Nepal) and became a noted center of Islamic learning under the later Sharqi dynasty.
Defeated by Bahlul Lodi of the Delhi Sultanate's Lodi dynasty at Benares in 1494; the last sultan Hussain Shah Sharqi fled to Bihar, ending Sharqi Jaunpur as an independent power.
Covers the Tughlaq dynasty's disintegration that produced breakaway successor states including Jaunpur; no dedicated English political-history monograph of the Jaunpur/Sharqi sultanate specifically was found verified in Open Library (an architectural study, 'The Sharqi Monuments of Jaunpur' (1922), exists but covers buildings, not the polity's political history).
