a British district of Hindustan, in the presidency of Bengal, bounded on the N. and E. by Bhagulpore, on the S.W. by Ramghur and Behar, on the W. by Behar and Patna, and on the N.W. by Tirhoot. It lies between Lat. 24. 20. and 26. 1. N., and Long. 85. 40. and 86. 50. E. The district has an area of 2558 square miles, and a population estimated at 800,000. It is intersected by numerous rivers, the principal of which are the Ganges, the Sukree, the Kiyul, the Bhagmattee, and the Gogaree. The district was acquired by the East India Company in 1765 by virtue of the firm of Shah Allum, Emperor of Delhi, granting to them the dewaney of Bengal, Behar, and Orissa. The town of Monghir is situated on the southern bank of the Ganges. It was the residence of Sultan Sujah during his government of the Bengal province, and was strengthened by him during his rebellion against his father, Shah Jehan. The fortifications have been for many years quite neglected, and the only part which remains is a small citadel, containing an arsenal and store-rooms. It is still surrounded by a wall and deep ditch, and is a place of considerable antiquity. It was an object of contention between the kings of Behar and Bengal in the early part of the sixteenth century. In 1762 it was the residence of Cossm Aly Khan, and was taken by the British the following year. The travelling distance from Calcutta is 300 miles.
