History

Integration of the Northwest Territory into a political unit, and settlement, depended on three factors: relinquishment by the British, extinguishment of states' claims west of the Appalachians, and usurpation or purchase of lands from the Native Americans. These objectives were accomplished correspondingly by the

Cessions by the states

Several states (Virginia, Massachusetts, New York, and Connecticut) had competing claims on the territory: Virginia claimed all of what were formerly Illinois Country and Ohio Country; Massachusetts claimed what are today southern Michigan and Wisconsin; Connecticut claimed a narrow strip across the territory just south of the Great Lakes; New York claimed an elastic portion of Iroquois lands between Lake Erie and the Ohio River. The western boundary of Pennsylvania was also ill-defined. Virginia's jurisdiction was limited to a few French settlements at the extreme western edge of the territory. Massachusetts's and Connecticut's claims were effectively lines on paper. New York had no colonial settlements or territorial government in the claimed lands. The western border of Pennsylvania, previously assumed to run in a north by northeast zigzag, was resolved in 1780 by the Continental Congress. The Mason–Dixon line was extended westward to a point five degrees of longitude (about 260 miles) from the Delaware River and the western boundary extended to run due north from the westernmost extent of the Mason–Dixon line to the 43rd parallel. This incorporated the eastern part of Ohio Country as western Pennsylvania, and set the eastern boundary of federal lands. "Unlanded" states, such as Maryland, refused to ratify the Articles of Confederation so long as these states were allowed to keep their western territory, fearing that those states could continue to grow and tip the balance of power in their favor under the proposed system of federal government. As a concession to obtain ratification, these states ceded their claims on the territory to the federal government: New York in 1780, Virginia in 1784, and Massachusetts and Connecticut in 1785. So the majority of the territory became public land owned by the U.S. government. Virginia and Connecticut reserved two areas to use as compensation to military veterans: The

was the first organization of the territory by the United States; it provided a process for dividing the territory into individual states. The Land Ordinance of 1785 established a standardized system for surveying the land into saleable lots, although Ohio was partially surveyed several times using different methods, resulting in a patchwork of land surveys in Ohio. Some older French communities' property claims based on earlier systems of long, narrow lots also were retained. The rest of the Northwest Territory was divided into roughly uniform square townships and sections, which facilitated land sales and development. The ordinance also stipulated that the territory would eventually form three to five new states.


Founding

Under the Northwest Ordinance of 1787, which created the Northwest Territory, General St. Clair was appointed governor. When the territory was divided in 1800, he briefly served as governor of the Northwest Territory remnant that included Ohio, the eastern half of Michigan, and a sliver of southeastern Indiana called "The Gore". St. Clair formally established the government on July 15, 1788, at Marietta. In 1790, he renamed the settlement of Losantiville

, after the Society of the Cincinnati, and moved the administrative and military center to Fort Washington. As Governor, he formulated the Maxwell's Code (named after its printer, William Maxwell), the first written criminal and civil laws of the territory. Maxwell's Code consisted of thirty-seven different laws with the stipulation that the laws had to have been passed previously in one of the original thirteen states. The laws restructured the court system then in effect in the Northwest Territory. They also protected residents against excessive taxes and declared that English common law would be the basis of legal decisions and laws in the Northwest Territory.


Northwest Indian War

The young United States government, deeply in debt following the Revolutionary War and lacking authority to tax under the Articles of Confederation, planned to raise revenue from the methodical sale of land in the Northwest Territory. This plan necessarily called for the removal of both Native American villages and squatters from lands west of Appalachia, loosely, the territory called "Ohio Country" and beyond. Difficulties with Native American tribes and a supporting British military presence presented continuing obstacles for American expansion. The area making up the Ohio Country had been contested for over a century, beginning with the 17th-century Beaver Wars. The

Although an investigation exonerated him, St. Clair resigned his army commission in March 1792 at the request of President Washington, but continued to serve as Governor of the Northwest Territory. After St. Clair's ignominious defeat, In June 1792, President Washington tapped revolutionary war hero Major General "Mad" Anthony Wayne to avenge St. Clair and assert sovereignty over the western frontier. Wayne was commissioned to form a new army of 5120 professional soldiers, dubbed the "Legion of the United States". Wayne recruited and trained his army in Pennsylvania, and moved them to southwestern Ohio in fall of 1793. There they were joined by the Kentucky Militia under Major General Charles Scott. Over the next ten months, the armies marched north up the Great Miami and Maumee River valleys toward the Miami capital of Kekionga. Along the way Wayne's legion built a series of outpost forts including Fort Greene Ville, Fort Recovery and Fort Defiance. Fierce battles occurred around some of these but none of Wayne's forts were ever taken by the Native Americans. In mid 1794, the British built Fort Miamis near what is today Toledo, Ohio, to forestall Wayne's putative advance on the British stronghold at Detroit. The final battle of Wayne's campaign occurred within the scope of this fort. The military campaign of Gen. Wayne against the Western Confederacy, who were supported by a company of troops from Lower Canada, culminated with victory at the

The Continental Congress' title to the lands north of the Ohio River was derived from the Treaty of Paris (1783), the Treaty of Fort McIntosh, and the cessions of four states.

along the eastern border of Ohio in 1786–1789. Direct sales of federal lands to individual homesteaders started here. In some cases, the government granted or donated land for special purposes. Settlement followed the forts, whether garrisoned or not. Lack of a garrison meant that threat of Native American attack had become negligible. This was true everywhere in Ohio before 1800 except the northwest sector above the Greenville Treaty line. It became true in Indiana after the Battle of Tippecanoe in 1811; by 1813 Battle of the Thames where Tecumseh was defeated and killed, the frontier had essentially moved to west of the Mississippi. The first U.S. military garrisons in the territory were Fort Patrick Henry, Vincennes, Indiana (1779), Fort Clark at Falls of the Ohio, Indiana (1783), and Fort Harmar in Ohio (1785). The first settlements were at these locations. The first land grant was to George Rogers Clark in 1781 at Falls of the Ohio on the Indiana side; he went on to found the settlement of Clarksville. The first two land purchases were large tracts of land sold to John Symmes ( Symmes Purchase) in 1788 and two tracts sold to Ohio Company in 1787 and 1792 (

). Settlement of these areas was spearheaded by Losantiville and Marietta, respectively. In 1792, Congress donated 100,000 acres to Ohio Company as a buffer zone against Native American incursion around the settled area. The vexing land claims by inhabitants of the old French Vincennes Tract were finally resolved by what was dubbed the 'Vincennes donation lands' embodied in a federal land act of 1791. Federal land sales in Indiana (then a part of Indiana Territory starting in 1800) began in 1801, through the Cincinnati land office. After the Revolutionary War ended,

The Northwest Territory doubled the size of the United States, and establishing it as free of slavery proved to be of tremendous importance in the following decades. It encompassed what became Ohio, Indiana, Illinois, Michigan, Wisconsin and part of Minnesota. Putnam, in the Puritan tradition, was influential in establishing education in the Northwest Territory. Substantial amounts of land were set aside for schools. Putnam had been one of the primary benefactors in the founding of Leicester Academy in Massachusetts, and similarly, in 1798, he created the plan for the construction of the Muskingum Academy (now

By the time of Ohio statehood, there were as many as 50 named towns in Northwest and Indiana Territories, a few, like Vincennes, with thousands of settlers, and dozens of unnamed settlements below the Treaty Line in Ohio. Following settlement of the frontier, the great wave of colonial immigration flowed westward, founding the great cities of the eventual 6 states of the Territory which is now the midwestern United States early in the 19th century: Detroit (<1800), Cleveland (1796), Columbus (1812), Indianapolis (1822), Chicago (1833), Milwaukee (1846), Minneapolis (1847).

Northwest Ordinance

The Northwest Ordinance of 1787 established the Northwest Territory, and defined its boundaries, form of government, and administrative structure. In particular, it defined the bodies of government, established the legal basis of land ownership, provided for abolition and transfer of state territorial claims, made rules for admission of new states, established public education, recognized and codified 'natural rights', prohibited slavery, and defined the land rights and applicability of laws to the Native Americans.

General Assembly

The General Assembly of the Northwest Territory consisted of a Legislative Council (five members chosen by Congress) and a House of Representatives consisting of 22 members elected by the male freeholders in nine counties. The first session of the Assembly was held in September 1799. Its first important task was to select a non-voting delegate to the U.S. Congress. Locked in a power struggle with Governor St. Clair, the legislature narrowly elected William Henry Harrison as the first delegate over the governor's son, Arthur St. Clair, Jr. Subsequent congressional delegates were William McMillan (1800–1801) and Paul Fearing (1801–1803).


Land ownership

The Northwest Ordinance of 1787 established the concept of fee simple ownership, by which ownership was in perpetuity with unlimited power to sell or give it away.


Prohibition of slavery

The ordinance was the first of its kind in prohibiting slavery in a U.S. territory.

Education

The Northwest Ordinance called for a public university for the education, settlement and eventual statehood of the frontier of Ohio and beyond. Article 3 stated, "Religion, morality, and knowledge being necessary to good government and the happiness of mankind, schools and the means of education shall forever be encouraged." The Land Ordinance of 1785 created an innovation in public education when it reserved resources for local public schools. The ordinance divided the territory into 36 mile2 townships, and each township was further divided into 36 one mile2 tracts for purposes of sale. The ordinance then stated that "there shall be reserved from sale the lot No. 16 of every township for the maintenance of public schools within the said township."

Early settlements were outside or nearby forts: Clarksville, Vincennes, Kaskaskia (French), Losantiville, and the Ohio Company settlements at Marietta and Waterford/Beverly.
