JIONPOOR, or JOANPORE, a district of Hindustan, in the N.W. provinces, included principally between N. Lat. 26. and 27. It is bounded on the N.W. by the territory of Oude; on the N.E. by Azimghur; on the E. by Gha-zee-poor, and on the S. by Benares and Allahabad, and embraces an area of 1552 square miles, with a population of 798,503. It is well watered, and extremely fertile; and the soil is under good cultivation, and well covered with wood. The inhabitants are Mohammedans and Hindus; the latter preponderating in the proportion of 15 to 1. Of the Hindus there was one tribe amongst whom the practice of female infanticide greatly prevailed; but, by the humane influence of the British government, it has been altogether abolished. This district came into the possession of the British in 1775, as forming part of the Benares zemindary.
