During the reign of the Mughal emperor Akbar
(1542-1605), the state of Bengal was ruled by Sulaiman, the governor of South Bihar. Sulaiman accepted the overlordship of Akbar. Sulaiman was succeeded by his son Daud, who revolted against the Emperor by declaring himself independent and attacking the outpost of Zamania on the eastern frontier of the Empire.
Emperor Akbar marched against Daud and expelled him from Patna (now the capital of Bihar) and Hajipur (in Bengal) in 1574. Akbar put Munim Khan in charge of Bengal. Daud was defeated by the
Mughals at Tukorai (in Bengal). Though Daud won back the territory for a short while in 1575, he was defeated and killed near Rajmahal in 1576. Thus Bengal came wholly under Mughal rule.
