Patna, called also Azimabad, a city of Bengal, 140 miles E. of Benares by rail, extends 9 miles along the Ganges and 2 miles back from the river. The chief buildings are the Gola or government granary (1786), the government opium-factories, Patna College, the shrine of Shah Arzani, the mosque of Slier Shah, a Roman Catholic church, and a Mohammedan college. Its railway communication, and its central position at the junction of three great rivers, the Son, Gandak, and Ganges, render Patna of great importance as a commercial centre. Pataliputra was founded about 600 B.C. The massacre here of British prisoners in 1763 led to annexation; and mutiny broke out at Dinapur, the military station west of Patna, in 1857. Bankipur, the civil station, between the city and Dinapur, was in 1905 made a sub-capital for Western Bengal. Pop. (1872) 158,900; (1881)170,654; (1901)134,785.
