The independence of Bengal, due partly to the weakness and preoccupation of the sovereigns of Delhi between 1338 and 1539, and partly to the existence, between 1394 and 1476, of the buffer state of Jaunpur, dated from the later days of the reign of Muhammad Tughluq, and endured, despite the two abortive attempts of Fīrūz Tughluq to subvert it in the reigns of Ilyās and his son Sikandar, until Humāyūn destroyed it by establishing himself, for three months in 1539, on the throne of Gaur. It was restored by Sher Khān’s defeat of Humāyūn at Chausa, but again destroyed by Sher Shāh after his ascent of the imperial throne.
