JIONPOOR, or JOANPORE, a district of Hindustan, in the province of Allahabad, included principally between the twenty-fifth and twenty-sixth degrees of north latitude. It is situated between the river Gogra on the east, and the Ganges on the south; to the north it is bounded by the Gogra and part of Oude; and on the west it has the nabob of Oude's territories. It is well watered, and extremely fertile; and the soil is under good cultivation, and well covered with wood. The inhabitants are Mahomedans and Hindus, in nearly equal proportions. 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 in a great measure abolished. This district came into the possession of the British in 1775, as forming part of the Benares zemindary. The principal towns are Jionpoor, Gazypoor, and Azimgar.
