Ghoom, or Ghoom, a large district of Afghanistan, situated between the 35th and 37th degrees of N. Lat, and the 67th and 69th degrees of E. Long. This was formerly one of the Persian governments; but in the 12th century its chiefs became independent, overturned the Ghiznian empire, and carried their arms as far as Benares. One of their slaves, named Cuttub, founded the Mohammedan kingdom of Delhi about 1206. This country was overrun in the 13th and 14th centuries by the armies of Genghis Khan and Tamerlane, and it is now in possession of the Usbec Tartars. The Ghory tribe, being of pastoral habits, have emigrated to the vicinity of Peshawur, and are now subdivided into three tribes. Its chief towns are Ghoor and Firoy Koh. Ghoor is the name of the capital, and was once the residence of a long line of sovereigns. It was taken by the king of Kharezm, and was subsequently sacked by the armies of Genghis and Tamerlane, from which it has never recovered, and is now scarcely known. Long. 67. 48. E., Lat. 35. 45. N.
