came part of the territory of the United States. The Ohio Company, organized in New England in 1787, composed of men who had served in the Revolutionary War, purchased from the government a large tract N. of the Ohio, paying for it in Continental currency. The first permanent settlement was made at Marietta in 1788. Cincinnati was founded soon after, and the settlement of the S. section of the territory progressed rapidly. In 1791 the Indian became stirred up by the encroachments of the whites, and a war ensued, which at first proved disastrous to the United States troops, but was finally ended in victory by General Wayne, in 1794. In the treaty of peace that followed, the Indians ceded a large section of territory, in which several new towns were quickly established. Ohio formed part of the Northwest Territory till 1800, when it was organized as a separate Territory, Chillicothe being made the seat of government. In 1802 a constitution was adopted for the “Eastern Division of the Territory N. W. of the Ohio,” under the name of Ohio, and it was formally admitted into the Union on Feb. 19, 1803. Steamboat navigation on the Ohio began in 1812; excavation of the State canals began in 1825, and was completed in 1844; and the first railroad, begun in 1837, was opened to traffic by 1842. Ohio took an active part in the Civil War, and since the war has given seven Presidents to the Union—Grant, Hayes, Garfield, Harrison, McKinley, Taft, and Harding, all born in this State.
