Mughal Emperor Farrukhsiyar granted a Firman to the East India Company for duty free trading rights in Bengal. Farrukhsiyar was the son of Azim-ush-Shan (the second son of emperor Bahadur Shah I) and Sahiba Nizwan. He was the emperor of Mughal from 1713 to 1719 after he murdered Jahandar Shah. In 1717, Farrukhsiyar issued a farman giving the British East India Company the right to reside and trade in the Mughal kingdom Bengal. They were allowed to trade freely, except for a yearly payment of 3,000 rupees. This was because William Hamilton, a surgeon associated with the company cured Farrukhsiyar of a disease. The company was given the right to issue dastak (passes) for the movement of goods, which was misused by company officials for personal gain.
