and made the British pay 150,000 Tk for blocking Mughal and Armenian trade ships. His maternal grandson Sirajuddaulah succeeded him when he died in 1756. Sirajuddaulah tried to stop uncertified trade in Bengal. Because of this he clashed with British merchants and was eventually defeated by 1757 in Polashi.

A Portuguese settlement was also created at Satgaon. In 1579, with a land grant from Akbar, the Portuguese created another station at Hooghly. The Portuguese traded and proselytised until 1632 when they were expelled by Shah Jahan, who allowed them to re-enter in the next year. The hostility towards them was a consequence of piracy by the Portuguese and Maghs. By 1651 the British obtained control of Hooghly. The Portuguese presence came to an end.

Alivardi Khan was perturbed by the stipulation in the order which provided the British with tax exemptions on the transportation of goods. This meant lower revenues for Alivardi Khan.
