Manissa, Or Manisa (anc. Magnesia and Sipy-lum), a city of Asia Minor, in the vilayet of Aidin, on the S. bank of the Hermus, and on the N. slope of Mt. Sipylus, about 20 m. N. E. of the city of Smyrna; pop. estimated from 30,000 to 60,000, chiefly Turks, with nearly 4,000 Greeks and a number of Armenians and Jews. There are numerous mosques, four Roman Catholic and several Creek and Armenian churches, and four synagogues. Among the public buildings are those for the Turkish lieutenant governor and for the Creek bishop. a splendid khan, a district lunatic asylum, the Ottoman bank, the railway Nation, and the new bazaar. The finest palace is occupied by the Karaosmanglu family, the former princes of Caramania, once omnipotent here, and still large landed proprietors. The principal export is cotton, which has been produced in considerable quantities since the civil war in the United States; and the Smyrna railway, opened in 1865 of which Manissa is the last station before reaching Kassaba, has rendered the cotton trade still more active in the two localities.
