History

In the 16th century, control of the river valley passed back-and-forth between Algonquian-speaking Shawnee and the Iroquois. The Shawnee, or Shaawanwaki, Shaawanooki and Shaawanowi lenaweeki, are a people native to North America. The Iroquois Confederacy (also known as the "League of Peace and Power" the "Five Nations" the "Six Nations" or the "People of the Longhouse 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. This article is about the country For a topic outline on this subject see List of basic France topics. The 18th century lasted from 1701 to 1800 in the Gregorian calendar, in accordance with the Anno Domini / Common Era numbering system The Kingdom of Great Britain, also known as the United Kingdom of Great Britain, was a State in northwest Europe, in existence from 1707 to 1800 The Allegheny Mountain Range (also spelled Alleghany and Allegany) &mdash informally the Alleghenies &mdash is part of the vast Appalachian 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. The Ohio Country (sometimes called the Ohio Territory) was the name used in the 18th century for the regions of North America west of the Appalachian Mountains The French and Indian War (1754&ndash1763 was the North American chapter of the Seven Years' War. Events and Trends Scientific Navigation is developed The Seven Years' War ( 1756 - 1763) fought between two rival alliances During the war, the village of Kittaning, the principal Shawnee settlement on the river, was completely destroyed by British reprisal raids from central Pennsylvania. Kittanning was an 18th century Native American village in the Ohio Country, located on the Allegheny River at present-day Kittanning Pennsylvania The Kittanning Expedition, also known as the Armstrong Expedition or the Battle of Kittanning was a raid during the French and Indian War that led

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 Treaty of Paris, often called the Peace of Paris, or the Treaty of 1763, was signed on February 10, 1763, by the kingdoms of Great Britain 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. In this article the inhabitants of the thirteen colonies that supported the American Revolution are primarily referred to as "Americans" with occasional references to "Patriots"

During the 19th century, the river became a principal means of navigation in the upper Ohio valley, especially for the transport of coal. The 19th century of the Common Era began on January 1, 1801 and ended on December 31, 1900, according to the Gregorian calendar 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. East Brady is a borough in Clarion County, Pennsylvania, United States and is part of the Pittsburgh DMA. In 1859, the first U. S. petroleum was drilled north of the river at Titusville. Titusville is a city in Crawford County, Pennsylvania, United States.

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.
