2 History

In the 16th century control of the river valley passed back-and-forth between Algonguin-speaking Shawnee and the Iroquois. By the time of the arrival of the French in the early 18th century, the Shawnee were once again in control and formed an alliance with the French against the incursion of British settlement across the Allegheny Mountains. The conflict over the expansion of British settlement into the Allegheny Valley and the surrounding Ohio Country was a primary cause of the French and Indian War in the 1750s. During the war, the village of Kittaning the principal Shawnee settlement on the river, was completely destroyed by British reprisal raids from central Pennsylvania.

Nevertheless, the British, after gaining control of the area in the 1763 Treaty of Paris, kept the area closed to white settlement, in part to repair and maintain relations with the Native Americans. The pressure to open the river valley and the surrounding area to settlement is considered by historians to be one of the root causes of the American Revolutionary War in the following decade.

During the 19th century, the river became a principal means of navigation in the upper Ohio valley, especially for the transport of coal. Although the building of the railroads lessened the importance of the river somewhat, the lower river (navigable as far as East Brady, Pennsylvania through locks) has continued to serve as route of commercial transportation until the present day. In 1875, the first U.S. petroleum was drilled north of the river at Titusville.

In 1965 the completion of the federally-sponsored Kinzua Dam for flood-control in northwestern Pennsylvania east of Warren created the long Allegheny Reservoir , part of which is included in the Allegheny National Recreation Area . The dam flooded parts of lands deeded "forever" to the Seneca tribe and to Cornplanter and his descendents.
