The Treaty of Alinagar was concluded by East India Company official Robert Clive after the recovery of Calcutta on January 2, 1757, from Nawab Siraj-ud Daulah. The treaty would be followed by the Battle of Plassey, in which the British would defeat the nawab and take over Bengal.
Siraj-ud-Daulah had captured Calcutta in June 1756 from the British and had named it Alinagar. But after the British regained Kolkata, the nawab signed the treaty as he wanted to secure himself from an attack by the Afghans.
The treaty recognised all the provisions of Mughal Emperor Farrukhsiyar’s farman of 1717, allowing exemption of duties on British goods in Bengal, the British to fortify Calcutta and to establish a mint.
