The Jaunpur Sultanate attained its greatest height under the younger brother of Mubarak Shah, who ruled as Shams ud-din Ibrahim Shah (ruled 1402-1440). To the east, his kingdom extended to Bihar, and to the west, to Kanauj; he even marched on Delhi at one point. Under the aegis of a Muslim holy man named Qutb al-Alam, he threatened the Sultanate of Bengal under Raja Ganesha.[3]
During the reign o
f Husain Shah (1456–76), the Jaunpur army was perhaps the biggest in India, and Husain decided to attempt a conquest of Delhi. However, he was defeated on three successive attempts by Bahlul Khan Lodi. Finally, under Sikandar Lodi, the Delhi Sultante was able to reconquer Jaunpur in 1493, bringing that sultanate to an end. The Jaunpur Sultanate was a major center of Urdu and Sufi knowledge and culture. The Sharqi dynasty was known for its excellent communal relations between Muslims and Hindus, perhaps stemming from the fact that the Sharqis themselves were originally indigenous converts to Islam, as opposed to descendants of Persians or Afghans. Jaunpur's independence came to an end in 1480, when the city was conquered by Sikander Lodhi, the Sultan of Delhi. The Sharqi kings attempted for several years to retake the city, but ultimately failed. Although many of the Sharqi monuments were destroyed when the Lodis took the city, several important mosques remain, most notably the Atala Masjid, Jama Masjid (now known as the Bari (big mosque) Masjid) and the Lal Darwaza Masjid. The Jaunpur mosques display a unique architectural style, combining traditional Hindu and Muslim motifs with purely original elements. The old bridge over the Gomti River in Jaunpur dates from 1564, the era of the Mughal emperor Akbar. The Jaunpur Quilla, a fortress from the Tughlaq era, also remains in ruined form. Jaunpur district was annexed into British India based on the Permanent settlement of 1779, and thus was subject to the Zamindari system of land revenue collection. During the Revolt of 1857 the Sikh troops in Jaunpur joined the Indian rebels. The district was eventually reconquered for the British by Gurkha troops from Nepal.
