Although Ahmadnagar district was created as early as in 1818, modern history of Ahmadnagar may be said to have commenced from 1869, the year in which parts of Nasik and Sholapur which till then had comprised Nagar were separated and the present Nagar district was formed. Ahmednagar District was created after the defeat of the Maratha Confederacy in the Third Anglo-Maratha War in 1818, when most of the Peshwa’s domains were annexed to British India. The district remained part of the Central division of Bombay Presidency until India’s independence in 1947, when it became part of Bombay State, and in 1960 the new state of Maharashtra.
