Mohammed, sultan of Carizme, reigned in Sogdiana when it was invaded (A.D. 1218) by Zingis and his Moguls. The Oriental historians (see D'Herbelot, Petit de la Croix, etc.) celebrate the populous cities which he ruined, and the fruitful country which he desolated. In the next century the same provinces of Chorasmia and Mawaralnahr were described by Abulfeda (Hudson, Geograph. Minor. tom. iii.). Their actual misery may be seen in the Genealogical History of the Tartars, p. 423-469.
