The Great Bengal famine of 1770 struck Bengal and Bihar between 1769 and 1770 and affected some 30 million people, which was about one third of the current population of the area. It occurred during a period of dual governance in Bengal. This existed after the East India Company had been granted the diwani, or the right to collect revenue, in Bengal by the Mughal emperor in Delhi, but before it had wrested the nizamat, or control of civil administration, which continued to lie with the Mughal governor, the Nawab of Bengal, Najmuddin Ali Khan (Nazm-ud-Daula) (1765–72). Crop failure in autumn 1768 and summer 1769 and an accompanying smallpox epidemic were thought to be the manifest reasons for the famine. The East India Company had farmed out tax collection on account of a shortage of trained administrators, and the prevailing uncertainty may have worsened the famine's impact.
