Even though the British had established a trading post at Fort William (in modern-day Kolkata), Bengal Presidency acquired its proper form after the Battle of Buxar in 1764.
 As an outcome of the Indian defeat, Shuja-ud-Daula of Oudh and the Mughal Emperor Shah Alam II signed the Treaty of Allahabad, granting the East India Company rights to collect revenues from large parts of eastern India.
 Early Bengal Presidency issues were stuck under the name of the Mughal Emperor Alamgir II, and later Shah Alam II.
  The monetary system followed (which was to be an Indian standard till 1 April 1957) was, 
1 pie = ​¹⁄₃ pice = ​¹⁄₁₂ anna
1 pice = ​¹⁄₄ anna = ​¹⁄₆₄ rupee
1 anna = ​¹⁄₁₆ rupee
15 rupees (approximately) = 1 mohur
