of the Mughals launched against Shivaji, which Shaista Khan the Mughal governor
undertook between 1660 and 1664. It was conducted from
Aurangabad and the Mughal army initially met with good success, capturing core
areas of Shivaji's domains, like Pune, Junnar, Chakan
and North Konkan. The fort at Chakan 'Sangrama Durga' was captured after a
fierce battle with the Maratha garrison commander named PhirangojiNarsaley and renamed 'Islamabad'. On 5 April 1663,
Shivaji launched a daring midnight raid on Shaista Khan's retinue (by now
stationed in Shivaji's own mansion in Pune) and almost killed the Khan - who
famously escaped having received the blow of Shivaji's sword on his fingers,
while he escaped through the window!
Irate as Aurangzeb was with this fiasco, he transferred Shaista Khan to the
governorship of Bengal where he remained in charge for a long time - during
which he encouraged European traders. It was under his tenure as the governor,
the first Anglo-Mughal war ('Child's War') broke out and led to the
establishment of Calcutta.
Apart from Chakan, there were many other
places named 'Islamabad' - Chittagong and Mathura have been mentioned above,
but Bhiwandi near Mumbai is also one more instance.
