Islam Khan was appointed as the
Subahdar of
Bengal by Mughal Emperor
Jahangir in 1606 AD. Islam led a successful campaign against the Baro Bhuiyans and shifted the capital of Bengal to Dhaka and gave it the name Jahangirnagar in 1610 AD. Dhaka emerged as the twelfth largest city of the world in the 17th century.
Shah Shuja, the second son of Mughal Emperor
Shahjahan, who was appointed as the Subahdar of Bengal province in 1651 AD, shifted the capital of Bengal to
Rajmahal from Dhaka. In 1658 AD Emperor Shahjahan's sons were engaged in a rivalry that resulted in a series of battles. Shah Shuja led a campaign to
Agra from Bengal and was defeated by his brother
Aurangzeb. Aurangzeb sent Mir Jumla II, an expert in naval warfare to deal with Shah Shuja in the Ganges river basin of Bengal. After Shah Shuja fled to
Arakan in 1660 AD, Mir Jumla II was appointed as the Subahdar of Bengal by emperor Aurangzeb. Mir Jumla II reestablished Dhaka as the capital of Bengal province. He constructed a number of structures including roads, bridges, culverts and several forts to modernise the city. ==History==
