In the United States, an independent city is a city that is not in the territory of any county or counties with exceptions noted below.
 Of the 41 independent U.S. cities, 38 are in Virginia, whose state constitution makes them a special case.
 The three independent cities outside Virginia are Baltimore, Maryland; St. Louis, Missouri; and Carson City, Nevada.
 The U.S. Census Bureau uses counties as its base unit for presentation of statistical information, and treats independent cities as county equivalents for those purposes.
 Baltimore, Maryland is the most populous independent city in the United States.
The state of Wisconsin in the United States has 72 counties.
 The land that eventually became Wisconsin was transferred from British to American control with the 1783 signing of the Treaty of Paris.
 It was an unorganized part of the Northwest Territory until 1802 when all of the land from St. Louis north to the Canadian border was organized as St. Clair County.
 When Illinois was admitted to the union in 1818, Wisconsin became part of the Territory of Michigan and divided into two counties: Brown County in the northeast along Lake Michigan and Crawford County in the southwest along the Mississippi River.
 Iowa County was formed in 1829 from the Crawford County land south of the Wisconsin River.
 Brown County's southern portion was used to form Milwaukee County in 1834.
 The state of Wisconsin was created from Wisconsin Territory on May 29, 1848, with 28 counties.
On May 6, 1812, an act of Congress was passed which set aside bounty lands as payment to volunteer soldiers for the War against the British (War of 1812).
 The land was set aside in western territories that became part of the present states of Arkansas, Michigan and Illinois.
St. Louis ( ) is an independent city and major U.S. port in the state of Missouri, built along the western bank of the Mississippi River, on the border with Illinois.
 The city had an estimated 2016 population of 311,404, and is the cultural and economic center of the Greater St. Louis area (home to 2,916,447 people), making it the largest metropolitan area in Missouri and the 19th-largest in the United States.
 Nine of the ten Fortune 500 companies based in Missouri are located within the St. Louis metropolitan area.
The Iowa District was a region of north-central North America west of the Mississippi River claimed by the United States.
 From June 28, 1834 to July 4, 1838, it was part of the Michigan Territory and, later, the Wisconsin Territory.
 It included not only the area which became the state of Iowa, but all of what would become Minnesota and parts of what would become North Dakota and South Dakota.
 In September 1834, at an extra session of the Sixth Legislative Assembly of Michigan, the Iowa District was divided into two counties.
 A border was drawn due west from the lower end of Rock Island in the Mississippi River.
 The territory north of this line (which started just south of the present-day Davenport) was named Dubuque County, and all area to the south of the line was named Demoine County.
The River Bend is a small region in western central Illinois and Southern Illinois that comprises parts of three counties: Madison, Calhoun, and Jersey.
 The name comes from a section of Mississippi River that flows roughly west to east instead of the usual north to south, causing a bend in the river.
 In this area, two other major rivers, the Missouri and the Illinois join the Mississippi River.
 This section of the Mississippi River is known as the Alton Lake
The term cape has a different tradition of usage in the American Midwest along the Mississippi River.
 The middle Mississippi River Valley once formed part of the French Colonies of Quebec and Louisiana, also referred to as Upper Louisiana (Haute-Louisiane) or the Illinois Country (Pays des Illinois).
 The Illinois Country also included the left bank of the Mississippi River in present-day Missouri.
Prairie Island Indian Community (Dakota: "Tinta Winta") is a Mdewakanton Sioux Indian reservation in Goodhue County, Minnesota, along the Mississippi River.
 Most of the reservation now lies within the city of Red Wing, which developed after this land was set aside.
The Morganza Spillway or Morganza Control Structure is a flood-control structure in the U.S. state of Louisiana along the western bank of the lower Mississippi River at river mile 280, near Morganza in Pointe Coupee Parish.
 The spillway stands between the Mississippi and the Morganza Floodway, which leads to the Atchafalaya Basin and the Atchafalaya River in south-central Louisiana.
 Its purpose is to divert water from the Mississippi River during major flood events by flooding the Atchafalaya Basin, including the Atchafalaya River and the Atchafalaya Swamp.
 The spillway and adjacent levees also help prevent the Mississippi from changing its present course through the major port cities of Baton Rouge and New Orleans to a new course down the Atchafalaya River to the Gulf of Mexico.
 The Morganza Spillway, operated by the U.S. Army Corps of Engineers, was opened during the 1973 and 2011 Mississippi River floods.
There are 67 counties in the state of Florida.
 It became a territory of the U.S. in 1821 with two counties complementing the provincial divisions retained as a Spanish territory: Escambia to the west and St. Johns to the east, divided by the Suwannee River.
 All of the other counties were apportioned from these two original counties.
 Florida became the 27th U.S. state in 1845, and its last county was created in 1925 with the formation of Gilchrist County from a segment of Alachua County.
 Florida's counties are subdivisions of the state government.
 In 1968, counties gained the power to develop their own charters. All but two of Florida's county seats are incorporated municipalities.
 The exceptions are Crawfordville, county seat of rural Wakulla County, and East Naples, located outside Naples city limits in Collier County.
