With the arrival of the "Europeans, both "Great Britain and "France claimed the area and both sent fur traders into the area to do business with the Ohio Country Indians. The Iroquois League claimed the region by right of conquest. The rivalry between the two European nations, the Iroquois, and the Ohio natives for control of the region played an important part in the French and Indian War from 1754 through 1760. After initially remaining neutral, the Ohio Country Indians largely sided with the French. Armed with supplies and guns from the French, they raided via the "Kittanning Path against British settlers east of the Alleghenies. After they destroyed "Fort Granville in the summer of 1756, the colonial governor "John Penn ordered Lt. Colonel "John Armstrong to destroy the Shawnee villages west of the Alleghenies.
The British defeated the French and their allies. Meanwhile, other British and colonial forces drove the French from "Fort Duquesne and building "Fort Pitt, the origin of the city of "Pittsburgh, Pennsylvania. In the "1763 Treaty of Paris, France ceded control of the entire Ohio region to Great Britain, without consulting its native allies, who still believed they had territorial claims. Colonies such as Pennsylvania and Virginia claimed some of the westward lands by their original charters.
Trying to improve relations with the Native Americans to encourage trade and avoid conflicts with colonists, "George III in his "Royal Proclamation of 1763 placed the Ohio Country in what was declared an "Indian Reserve, stretching from the "Appalachian Mountains west to the "Mississippi River and from as far north as "Newfoundland to "Florida. The British ordered the existing settlers (mostly French) to leave or get special permission to stay, and prohibited British colonists from settling west of the Appalachians.
The area was officially closed to European settlement by the "Royal Proclamation of 1763. The Crown no longer recognized claims that the colonies made on this territory. On June 22, 1774, the British Parliament passed the "Quebec Act; it annexed the region to the "province of Quebec. Colonists in the Thirteen Colonies considered this one of the "Intolerable Acts passed by Parliament, contributing to the American Revolution.
Despite the Crown's actions, "frontiersmen from the "Virginia and "Pennsylvania colonies began to cross the Allegheny Mountains and came into conflict with the Shawnee. The Shawnee referred to the settlers as the "Long Knives. Because of the threat posed by the colonists, the Shawnee and other nations of the Ohio Country chose to side with the British against the rebel colonists during the "American Revolutionary War.
Americans wanted to establish control over the region. In 1778, after "victories in the region by the Patriot general "George Rogers Clark, the Virginia legislature organized the first American civil government in the region. They called it the "Illinois County, which encompassed all of the lands lying west of the Ohio River to which Virginia had any claim. The high-water mark of the Native American struggle to retain the region was in 1782: the Ohio Nations and the British met in a council at the Chalawgatha village along the "Little Miami River to plan what was the successful rout of the Americans at the "Battle of Blue Licks, south of the Ohio River, two weeks later.
In 1783, following the "Treaty of Paris, Great Britain ceded the area to the "United States (US). The government immediately opened it to settlement by American pioneers, considering it unorganized territory. The Ohio Country quickly became one of the most desirable locations for Trans-Appalachian settlements, in particular among veterans of the Revolutionary War.
In the "Treaty of Fort McIntosh in 1785 and the "Treaty of Fort Harmar in 1789, the US fixed boundaries between United States and tribal lands. The "Shawnee and other tribes continued to resist US encroachment into their historic lands. This resistance led to the "Northwest Indian War after the Revolution, in which a coalition of Native American tribes tried to repulse US settlement; it lasted until 1795 but the Indians were finally defeated.
By 1800, many of the Shawnee had ceded their lands to the control of the United States in exchange for lands in "Missouri. The last great resistance to white settlement in the area was during the "War of 1812, when "Tecumseh led a war against the Americans that ended in the defeat of him and his people. By 1817, the Shawnee, as well as the other "Algonquian-speaking tribes in the region, had ceded all their lands to the United States.
Considered highly desirable, the area was subject to the overlapping and conflicting territorial ambitions of several eastern states, specifically:
Unlike the rest of the "Northwest Territory, which was surveyed more or less uniformly under the "Public Land Survey System, sections of the "Ohio Lands were incrementally granted to various parties and were surveyed using disparate survey systems. This created numerous problems with land deeds and claims in later years.
In 1784 the area was included within the Trans-Appalachian region, as defined by "Thomas Jefferson in his proposal to the Continental Congress to use the territory for the development of future states to be admitted to the Union. Jefferson proposed that the existing states surrender their respective claims to the region in order for its development to take place under national authority. One of the most contentious issues was whether or not slavery would be allowed in the area. At a time when northern states were "abolishing slavery and individual manumissions were high, northern representatives wanted to prohibit its expansion.
In 1787, "Congress passed the "Northwest Ordinance, establishing the boundaries of the region. Pennsylvania was granted the area around the headwaters of the Ohio River, and Virginia was granted the land south of the Ohio. The remaining area west of the Pennsylvania boundary and north of the Ohio became part of the newly formed "Northwest Territory, which included all the land of the United States west of "Pennsylvania and northwest of the "Ohio River. It covered all of the modern states of "Ohio, "Indiana, "Illinois, "Michigan, "Wisconsin, and the northeastern part of "Minnesota. The area covered more than 260,000 square miles (670,000 km2). Unprecedented settlement from "New England was spurred from the services that the new ordinance mandated. Chartered within the 1787 legislation, "Ohio University was the first institution of "higher education "chartered by an "act of Congress in America and the first university in the "Northwest Territory in 1804. Reverend Doctor "Manasseh Cutler was the entrepreneur of the venture to establish the university within the policies that arrived at its inclusion in the ordinance language.
The existing states surrendered all their claims to the Ohio Country land within the Northwest Territory. Connecticut and Virginia reserved the right to use certain lands in the new territory for grants as payment to veterans of the Revolutionary War, without claiming sovereignty over the reserved areas. These were known respectively as the "Connecticut Western Reserve and the "Virginia Military District.
The Northwest Ordinance prohibited slavery in the territory, but it did not free slaves who had already been taken into the territory by their masters. In some cases, it took decades for such slaves to gain freedom.
It was the first "organized territory in the United States. Its civil government was to be under the jurisdiction of the Congress. "Pioneers to the Ohio Country arrived at the confluence of the "Ohio and "Muskingum rivers on April 7, 1788, and established "Marietta, Ohio as the first permanent American settlement in the Territory.
The Ordinance acknowledged that the territory, as in the Jeffersonian proposal, would eventually be organized as future states of the Union, to be admitted when a jurisdiction achieved sufficient population to support a government. The "Ohio Territory" is sometimes used as a synonym for the Northwest Territory.
In 1802, the "Enabling Act specifically provided for the admission of new states, the first of which, Ohio, was admitted to the Union on February 19, 1803. Its admission has been celebrated as March 1, 1803, which was the date of the first meeting of the "Ohio state legislature.
