Northwest Territory in the context of "East North Central States"

Illinois (/ˌɪlɪˈnɔɪ/ IL-ih-NOY) is a state in the Midwestern region of the United States. It borders Lake Michigan to its northeast, the Mississippi River to its west, and the Wabash and Ohio rivers to its south. Of the fifty U.S. states, Illinois has the fifth-largest gross domestic product (GDP), the sixth-largest population, and the 25th-most land area. Its capital city is Springfield in the center of the state, and the state's largest city is Chicago in the northeast.

Present-day Illinois was inhabited by Indigenous cultures for thousands of years. The French were the first Europeans to arrive, settling near the Mississippi and Illinois rivers in the 17th century Illinois Country, as part of their sprawling colony of New France. A century later, the revolutionary war Illinois campaign prefigured American involvement in the region. Following U.S. independence in 1783, which made the Mississippi River the national boundary, American settlers began arriving from Kentucky via the Ohio River. Illinois was soon part of the United States' oldest territory, the Northwest Territory, and in 1818 it achieved statehood. The Erie Canal brought increased commercial activity in the Great Lakes, and the invention of the self-scouring steel plow by Illinoisan John Deere turned the state's rich prairie into some of the world's most productive and valuable farmland, attracting immigrant farmers from Germany, Sweden and elsewhere. In the mid-19th century, the Illinois and Michigan Canal and a sprawling railroad network facilitated trade, commerce, and settlement, making the state a transportation hub for the nation, especially in the city of Chicago, which became the world's fastest growing city by the late 19th century. By 1900, the growth of industrial jobs in the northern cities and coal mining in the central and southern areas attracted immigrants from Eastern and Southern Europe. Illinois became one of America's most industrialized states and remains a major manufacturing center. The Great Migration from the South established a large Black community, particularly in Chicago, which became a leading cultural, economic, and population center; its metropolitan area, informally referred to as Chicagoland, holds about 65% of the state's 12.8 million residents.

In United States law, an organic act is an act of the United States Congress that establishes an administrative agency or local government, for example, the laws that established territory of the United States and specified how they are to be governed, or established agency to manage certain federal lands. In the absence of organic law, the body of laws that define and establish a government, a territory is classified as unorganized.

The first such act was the Northwest Ordinance, passed in 1787 by the U.S. Congress of the Confederation (under the Articles of Confederation, predecessor of the United States Constitution). The Northwest Ordinance created the Northwest Territory in the land west of Pennsylvania and northwest of the Ohio River and set the pattern of development that was followed for all subsequent territories. The Northwest Territory covered more than 260,000 square miles and included all of the modern states of Ohio, Indiana, Illinois, Michigan, Wisconsin, and the northeastern part of Minnesota.

Ohio (/oʊˈhaɪ.oʊ/ oh-HY-oh) is a state in the Midwestern region of the United States. It borders Lake Erie to the north, Pennsylvania to the east, West Virginia to the southeast, Kentucky to the southwest, Indiana to the west, and Michigan to the northwest. Of the 50 U.S. states, it is the 34th-largest by area. With a population of nearly 11.9 million, Ohio is the seventh-most populous and tenth-most densely populated state. Its capital and most populous city is Columbus, with other major metropolitan centers including Cleveland and Cincinnati, as well as Dayton, Akron, and Toledo. Ohio is nicknamed the "Buckeye State" after its Ohio buckeye trees, and Ohioans are also known as "Buckeyes".

Ohio derives its name from the Ohio River that forms its southern border, which, in turn, originated from the Seneca word ohiːyo', meaning "good river", "great river", or "large creek". The state was home to several ancient indigenous civilizations, with humans present as early as 10,000 BC. It arose from the lands west of the Appalachian Mountains that were contested by various native tribes and European colonists from the 17th century through the Northwest Indian Wars of the late 18th century. Ohio was partitioned from the Northwest Territory, the first frontier of the new United States, becoming the 17th state admitted to the Union on March 1, 1803, and the first under the Northwest Ordinance. It was the first post-colonial free state admitted to the union and became one of the earliest and most influential industrial powerhouses during the 20th century.

Wisconsin is a state in the Upper Midwest and Great Lakes regions of the United States. It borders Minnesota to the west, Iowa to the southwest, Illinois to the south, Lake Michigan to the east, Michigan to the northeast, and Lake Superior to the north. With a population of about 6 million and an area of about 65,500 square miles, Wisconsin is the 20th-largest state by population and the 23rd-largest by area. It has 72 counties. The state's most populous city is Milwaukee. Its capital and second-most populous city is Madison; other urban areas include Green Bay and the Fox Cities.

Wisconsin's geography is diverse, with dense forests in the north (including Chequamegon–Nicolet National Forest), rugged unglaciated hills in the western Driftless Area, and wooded plains, lowlands, and farms stretching from the interior east to Lake Michigan. Wisconsin has the third-longest Great Lakes coastline, after Ontario and Michigan. At the time of European contact, the area was inhabited by Algonquian and Siouan nations, and today it is home to eleven federally recognized tribes. Originally part of the Northwest Territory, it was admitted as a state in 1848. During the 19th and early 20th centuries, many European settlers entered the state, mostly from Germany and Scandinavia. Wisconsin remains a center of German American and Scandinavian American culture, particularly in its cuisine, with foods such as bratwurst and kringle.

There are 102 counties in Illinois. The most populous of these is Cook County, the second-most populous county in the United States and the home of Chicago, while the least populous is Hardin County. The largest by land area is McLean County, while the smallest is Putnam County. Illinois's FIPS state code is 17 and its postal abbreviation is IL.

What is now Illinois was claimed as part of Illinois County, Virginia, between 1778 and 1782. Modern-day county formation dates to 1790 when the area was part of the Northwest Territory; two counties — St. Clair and Knox — were created at that time. Knox would later become a county in Indiana and is unrelated to the current Knox County in Illinois, while St. Clair would become the oldest county in Illinois. Successive territorial governments created 15 counties by the time Illinois achieved statehood in 1818. The last county created in the state, Ford County, was created by the Illinois government in 1859.

St. Clair County is the ninth most populous county in Illinois. Located directly east of St. Louis, the county is part of the Metro East region of the Greater St. Louis metropolitan area in southern Illinois. As of the 2020 United States census, St. Clair County had a population of 257,400, making it the second most populous county in Illinois outside the Northern Third. Belleville is the county seat and largest city.

Along the Mississippi River, Cahokia Village was founded in 1697 by French settlers and served as a Jesuit mission to convert tribes of the Illinois Confederation to Christianity. The area became the center of the French Illinois Country. Prior to the establishment of Illinois as a state, the government of the Northwest Territory created St. Clair County in 1790. In 1809, the county became the administrative center of the Illinois Territory and one of the two original counties of Illinois, alongside Randolph County. In 1970, the United States Census Bureau placed the mean center of U.S. population, which generally has moved west every decennial census, in St. Clair County.

The Pacific Northwest (PNW) is a geographic region in Western North America bounded by its coastal waters of the Pacific Ocean to the west and, loosely, by the Rocky Mountains to the east. Though no official boundary exists, the most common conception includes the U.S. states of Oregon, Washington, Idaho, and the Canadian province of British Columbia. Some broader conceptions reach north into Alaska and Yukon, south into Northern California, and east into western Montana. Other conceptions may be limited to the coastal areas west of the Cascade and Coast mountains.

The Northwest Coast is the coastal region of the Pacific Northwest, and the Northwest Plateau (also commonly known as "the Interior" in British Columbia), is the inland region. The term "Pacific Northwest" should not be confused with the Northwest Territory (also known as the Great Northwest, a historical term in the United States) or the Northwest Territories of Canada.

The Northwest Ordinance (formally An Ordinance for the Government of the Territory of the United States, North-West of the River Ohio and also known as the Ordinance of 1787), enacted July 13, 1787, was an organic act of the Congress of the Confederation of the United States. It created the Northwest Territory, the new nation's first organized incorporated territories between British North America and the Great Lakes to the north and the Ohio River to the south. The upper Mississippi River formed the territory's western boundary. Pennsylvania was the eastern boundary.

In the 1783 Treaty of Paris, which formally ended the American Revolutionary War, Great Britain ceded the region to the United States. However, the Confederation Congress faced numerous problems gaining control of the land such as the unsanctioned movement of American settlers into the Ohio Valley; violent resistance from the region's indigenous peoples; the continued presence of British outposts in the region and an empty U.S. treasury. The ordinance superseded the Land Ordinance of 1784, which declared that states would one day be formed within the region, and the Land Ordinance of 1785, which described how the Confederation Congress would sell the land to private citizens. Designed to serve as a plan for the development and settlement of the region, the 1787 ordinance lacked a strong central government to implement it. That need was addressed shortly with the formation of the U.S. federal government in 1789. The First Congress reaffirmed the 1787 ordinance and, with slight modifications, renewed it with the Northwest Ordinance of 1789.

Harriet Robinson Scott (c. 1820 – June 17, 1876) was an African American woman who fought for her freedom alongside her husband, Dred Scott, for eleven years. Their legal battle culminated in the infamous United States Supreme Court decision Dred Scott v. Sandford in 1857. On April 6, 1846, attorney Francis B. Murdoch had initiated Harriet v. Irene Emerson in the Circuit Court of St. Louis County, making the Scotts the first and only married couple to file separate freedom suits in tandem.

Born into slavery in Virginia, Harriet Robinson lived briefly in the free state of Pennsylvania before being taken to the Northwest Territory by Indian agent and slaveholder Lawrence Taliaferro. In 1836 or 1837, Harriet married Etheldred, an enslaved man who had been brought to Fort Snelling in present-day Minnesota by Dr. John Emerson, a military surgeon. Their civil wedding ceremony was officiated by justice of the peace Taliaferro, who never actually sold Harriet to Dr. Emerson, since slavery was illegal there.
