Wisconsin has been home to a wide variety of cultures over the past 14,000 years. The first people arrived around 10,000 BCE during the Wisconsin Glaciation. These early inhabitants, called Paleo-Indians, hunted now-extinct ice age animals such as the Boaz mastodon, a prehistoric mastodon skeleton unearthed along with spear points in southwest Wisconsin. After the ice age ended around 8000 BCE, people in the subsequent Archaic period lived by hunting, fishing, and gathering food from wild plants. Agricultural societies emerged gradually over the Woodland period between 1000 BCE to 1000 CE. Toward the end of this period, Wisconsin was the heartland of the “Effigy Mound culture”, which built thousands of animal-shaped mounds across the landscape. Later, between 1000 and 1500 CE, the Mississippian and Oneota cultures built substantial settlements including the fortified village at Aztalan in southeast Wisconsin. The Oneota may be the ancestors of the modern Ioway and Ho-Chunk nations who shared the Wisconsin region with the Menominee at the time of European contact. Other Native American groups living in Wisconsin when Europeans first settled included the Ojibwa, Sauk, Fox, Kickapoo, and Pottawatomie, who migrated to Wisconsin from the east between 1500 and 1700.
The first European to visit what became Wisconsin was probably the French explorer Jean Nicolet. He canoed west from Georgian Bay through the Great Lakes in 1634, and it is traditionally assumed that he came ashore near Green Bay at Red Banks.Pierre Radisson and Médard des Groseilliers visited Green Bay again in 1654–1666 and Chequamegon Bay in 1659–1660, where they traded for fur with local Native Americans. In 1673, Jacques Marquette and Louis Jolliet became the first to record a journey on the Fox-Wisconsin Waterway all the way to the Mississippi River near Prairie du Chien.Frenchmen like Nicholas Perrot continued to ply the fur trade across Wisconsin through the 17th and 18th centuries, but the French made no permanent settlements in Wisconsin before Great Britain won control of the region following the French and Indian War in 1763. Even so, French traders continued to work in the region after the war, and some, beginning with Charles de Langlade in 1764, settled in Wisconsin permanently, rather than returning to British-controlled Canada.
The British gradually took over Wisconsin during the French and Indian War, taking control of Green Bay in 1761 and gaining control of all of Wisconsin in 1763. Like the French, the British were interested in little but the fur trade. One notable event in the fur trading industry in Wisconsin occurred in 1791, when two free African Americans set up a fur trading post among the Menominee at present day Marinette. The first permanent settlers, mostly French Canadians, some Anglo-New Englanders and a few African American freedmen, arrived in Wisconsin while it was under British control. Charles de Langlade is generally recognized as the first settler, establishing a trading post at Green Bay in 1745, and moving there permanently in 1764. Settlement began at Prairie du Chien around 1781. The French residents at the trading post in what is now Green Bay, referred to the town as “La Baye”. However, British fur traders referred to it as “Green Bay”, because the water and the shore assumed green tints in early spring. The old French title was gradually dropped, and the British name of “Green Bay” eventually stuck. The region coming under British rule had virtually no adverse effect on the French residents as the British needed the cooperation of the French fur traders and the French fur traders needed the goodwill of the British. During the French occupation of the region licenses for fur trading had been issued scarcely and only to select groups of traders, whereas the British, in an effort to make as much money as possible from the region, issued licenses for fur trading freely, both to British and to French residents. The fur trade in what is now Wisconsin reached its height under British rule, and the first self-sustaining farms in the state were established as well. From 1763 to 1780, Green Bay was a prosperous community which produced its own foodstuff, built graceful cottages and held dances and festivities.
Wisconsin became a territorial possession of the United States in 1783 after the American Revolutionary War. In 1787, it became part of the Northwest Territory. As territorial boundaries subsequently developed, it was then part of Indiana Territory from 1800 to 1809, Illinois Territory from 1809 to 1818, and Michigan Territory from 1818 to 1836. However, the British remained in control until after the War of 1812, the outcome of which finally established an American presence in the area. Under American control, the economy of the territory shifted from fur trading to lead mining. The prospect of easy mineral wealth drew immigrants from throughout the U.S. and Europe to the lead deposits located at Mineral Point, Dodgeville, and nearby areas. Some miners found shelter in the holes they had dug, and earned the nickname “badgers”, leading to Wisconsin’s identity as the “Badger State”. The sudden influx of white miners prompted tension with the local Native American population. The Winnebago War of 1827 and the Black Hawk War of 1832 culminated in the forced removal of Native Americans from most parts of the state.
Following these conflicts, Wisconsin Territory was created by an act of the United States Congress on April 20, 1836. By fall of that year, the best prairie groves of the counties surrounding what is now Milwaukee were occupied by farmers from the New England states.
The Erie Canal facilitated the travel of both Yankee settlers and European immigrants to Wisconsin Territory. Yankees from New England and upstate New York seized a dominant position in law and politics, enacting policies that marginalized the region’s earlier Native American and French-Canadian residents. Yankees also speculated in real estate, platted towns such as Racine, Beloit, Burlington, and Janesville, and established schools, civic institutions, and Congregationalist churches. At the same time, many Germans, Irish, Norwegians, and other immigrants also settled in towns and farms across the territory, establishing Catholic and Lutheran institutions.
The growing population allowed Wisconsin to gain statehood on May 29, 1848, as the 30th state. Between 1840 and 1850, Wisconsin’s non-Indian population had swollen from 31,000 to 305,000. More than a third of residents (110,500) were foreign born, including 38,000 Germans, 28,000 British immigrants from England, Scotland, and Wales, and 21,000 Irish. Another third (103,000) were Yankees from New England and western New York state. Only about 63,000 residents in 1850 had been born in Wisconsin.
Nelson Dewey, the first governor of Wisconsin, was a Democrat. Dewey oversaw the transition from the territorial to the new state government. He encouraged the development of the state’s infrastructure, particularly the construction of new roads, railroads, canals, and harbors, as well as the improvement of the Fox and Wisconsin Rivers. During his administration, the State Board of Public Works was organized. Dewey, an abolitionist, was the first of many Wisconsin governors to advocate against the spread of slavery into new states and territories.
Politics in early Wisconsin were defined by the greater national debate over slavery. A free state from its foundation, Wisconsin became a center of northern abolitionism. The debate became especially intense in 1854 after Joshua Glover, a runaway slave from Missouri, was captured in Racine. Glover was taken into custody under the Federal Fugitive Slave Law, but a mob of abolitionists stormed the prison where Glover was held and helped him escape to Canada. In a trial stemming from the incident, the Wisconsin Supreme Court ultimately declared the Fugitive Slave Law unconstitutional. The Republican Party, founded on March 20, 1854, by anti-slavery expansion activists in Ripon, Wisconsin, grew to dominate state politics in the aftermath of these events. During the Civil War, around 91,000 troops from Wisconsin fought for the Union.
Wisconsin’s economy also diversified during the early years of statehood. While lead mining diminished, agriculture became a principal occupation in the southern half of the state. Railroads were built across the state to help transport grains to market, and industries like J.I. Case & Company in Racine were founded to build agricultural equipment. Wisconsin briefly became one of the nation’s leading producers of wheat during the 1860s. Meanwhile, the lumber industry dominated in the heavily forested northern sections of Wisconsin, and sawmills sprang up in cities like La Crosse, Eau Claire, and Wausau. These economic activities had dire environmental consequences. By the close of the 19th century, intensive agriculture had devastated soil fertility, and lumbering had deforested most of the state. These conditions forced both wheat agriculture and the lumber industry into a precipitous decline.
Beginning in the 1890s, farmers in Wisconsin shifted from wheat to dairy production in order to make more sustainable and profitable use of their land. Many immigrants carried cheese-making traditions that, combined with the state’s suitable geography and dairy research led by Stephen Babcock at the University of Wisconsin, helped the state build a reputation as “America’s Dairyland”. Meanwhile, conservationists including Aldo Leopold helped re-establish the state’s forests during the early 20th century, paving the way for a more renewable lumber and paper milling industry as well as promoting recreational tourism in the northern woodlands. Manufacturing also boomed in Wisconsin during the early 20th century, driven by an immense immigrant workforce arriving from Europe. Industries in cities like Milwaukee ranged from brewing and food processing to heavy machine production and tool-making, leading Wisconsin to rank 8th among U.S. states in total product value by 1910.
The early 20th century was also notable for the emergence of progressive politics championed by Robert M. La Follette. Between 1901 and 1914, Progressive Republicans in Wisconsin created the nation’s first comprehensive statewide primary election system, the first effective workplace injury compensation law, and the first state income tax, making taxation proportional to actual earnings. The progressive Wisconsin Idea also promoted the statewide expansion of the University of Wisconsin through the UW-Extension system at this time. Later, UW economics professors John R. Commons and Harold Groves helped Wisconsin create the first unemployment compensation program in the United States in 1932.
In the immediate aftermath of World War II, citizens of Wisconsin were divided over issues such as creation of the United Nations, support for the European recovery, and the growth of the Soviet Union’s power. However, when Europe divided into Communist and capitalist camps and the Communist revolution in China succeeded in 1949, public opinion began to move towards support for the protection of democracy and capitalism against Communist expansion.
Wisconsin took part in several political extremes in the mid to late 20th century, ranging from the anti-communist crusades of Senator Joseph McCarthy in the 1950s to the radical antiwar protests at UW-Madison that culminated in the Sterling Hall bombing in August 1970. The state undertook welfare reform under Republican Governor Tommy Thompson during the 1990s. The state’s economy also underwent further transformations towards the close of the 20th century, as heavy industry and manufacturing declined in favor of a service economy based on medicine, education, agribusiness, and tourism.
Two U.S. Navy battleships, BB-9 and BB-64, were named for the state.
In 2011, Wisconsin became the focus of some controversy when newly elected governor Scott Walker proposed, passed, and enacted the 2011 Wisconsin Act 10, which made large changes in the areas of collective bargaining, compensation, retirement, health insurance, and sick leave of public sector employees, among other changes. A series of major protests by union supporters took place that year in response to the changes, and Walker survived a recall election held the next year, becoming the first governor in United States history to do so. Walker enacted other bills promoting conservative governance, such as a right-to-work law, abortion restrictions, and legislation removing certain gun controls.
