Wisconsin (//) is a U.S. state located in the north-central United States, in the Midwest and Great Lakes regions. It is bordered by 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. Wisconsin is the 23rd state by total area and the 20th most populous. The state capital is Madison, and its largest city is Milwaukee which is located on the western shore of Lake Michigan. The state comprises 72 counties.
Wisconsin's geography is diverse, with the Northern Highland and Western Upland along with a part of the Central Plain occupying the western part of the state and lowlands stretching to the shore of Lake Michigan. Wisconsin is second to Michigan in the length of its Great Lakes coastline.
Wisconsin is known as "America's Dairyland" because it is one of the nation's leading dairy producers. Manufacturing and tourism are also major contributors to the state's economy.
The word Wisconsin originates from the name given to the Wisconsin River by one of the Algonquian-speaking American Indian groups living in the region at the time of European contact. French explorer Jacques Marquette was the first European to reach the Wisconsin River, arriving in 1673 and calling the river Meskousing in his journal. This spelling was later corrupted to Ouisconsin by other French explorers, and over time this version became the French name for both the Wisconsin River and the surrounding lands. English speakers anglicized the spelling to its modern form when they began to arrive in greater numbers during the early 19th century. The current spelling was made official by the legislature of Wisconsin Territory in 1845.
Throughout the course of its many variations, the Algonquian word for Wisconsin and its original meaning have both grown obscure. Interpretations may vary, but most implicate the river and the red sandstone that line its banks. One leading theory holds that the name originated from the Miami word Meskonsing, meaning "it lies red," a reference to the setting of the Wisconsin River as it flows by the reddish sandstone of the Wisconsin Dells. Numerous other theories have also been widely publicized, including claims that name originated from one of a variety of Ojibwa words meaning "red stone place," "where the waters gather," or "great rock."
