The Jaunpur sultanate was ruled by the Sharqi dynasty. The Khwajah-i-Jahan Malik Sarwar, the first ruler of the dynasty was a Wazir (minister) under Sultan Nasiruddin Muhammad Shah III Tughluq (1390 – 1394 CE). In 1394 CE, he established himself as an independent ruler of Jaunpur and extended his authority over Awadh and a large part of Ganga-Yamuna doab. The dynasty founded by him was named so because of his title Malik-us-Sharq (the ruler of the east). The most acclaimed ruler of this dynasty was Ibrahim Shah. The last ruler Hussain Shah was overthrown by Bahlul Lodi, and Jaunpur sultanate was permanently annexed to Delhi sultanate by Sikandar Lodi.
