Early history marks the site of an ancient
Mississippian culture settlement that flourished during the 10th to 13th centuries. 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
Iowa 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
Ojibwe,
Sauk,
Meskwaki,
Kickapoo, and
Potawatomi, who migrated to Wisconsin from the east between 1500 and 1700.
European settlements , depicted in a 1910 painting by Frank Rohrbeck, was probably the first European to explore Wisconsin. The mural is located in the
Brown County Courthouse in Green Bay. 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. Joseph Roi built the
Tank Cottage in
Green Bay in 1776. Located in
Heritage Hill State Historical Park, it is the
oldest standing building from Wisconsin's early years and is listed on the
National Register of Historic Places.
U.S. territory in
Prairie du Chien was built in the 1810s by fur traders. 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 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.
Statehood celebrating the 100th anniversary of Wisconsin statehood, featuring the state capitol building and map of Wisconsin. The Great Lakes, via 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. 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
American Civil War, around 91,000 troops from Wisconsin fought for the
Union. A number of Wisconsin regiments were distinguished, including three that served in the celebrated "
Iron Brigade"— the
2nd Wisconsin,
6th Wisconsin, and
7th Wisconsin. The
8th Wisconsin, another hard-fighting regiment, was often accompanied into battle by its mascot,
Old Abe, a bald eagle. in
Chase was built in 1903, as dairy farming spread across the state. 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 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.
Progressive era and World Wars campaigning, 1916. Wisconsin was among the earliest states to ratify the
Nineteenth Amendment. The early 20th century was notable for the emergence of
progressive politics championed by
Robert M. La Follette, who served as governor from 1901 to 1906 and U.S. senator from 1906 to 1925. 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. During
World War I, due to the neutrality of Wisconsin and many of its
Republicans,
Progressives, and
Conservatives, including
Germans and
Scandinavians who were a significant proportion of the state's population, Wisconsin began to be accused of being the "Traitor State" by many "hyper patriots." As the war raged on in Europe, La Follette led the antiwar movement in Wisconsin and steered a group of progressive senators in blocking a bill by President
Woodrow Wilson that would have armed merchant ships with guns. Many Wisconsin politicians, such as
Emanuel L. Philipp and
Irvine Lenroot, were accused of having divided loyalties. Even with outspoken opponents to the war, at the onset of the war, many Wisconsinites would abandon neutrality. Businesses, labor and farms all enjoyed prosperity from the war. With over 118,000 going into military service, Wisconsin was the first state to report for the national drafts conducted by the
U.S. military. As governor, Philipp was successful in combating
anti-German hysteria in the state. The progressive
Wisconsin Idea also promoted the statewide expansion of the University of Wisconsin through the
UW–Extension system at this time. In 1932, UW economics professors
John R. Commons and Harold Groves helped Wisconsin create the United States' first
unemployment compensation program. Other
Wisconsin Idea scholars at the university generated the plan that became the New Deal's
Social Security Act of 1935, with Wisconsin expert
Arthur J. Altmeyer playing a key role. announces formation of the
National Progressives of America, 1938 After La Follette died, his sons
Philip and
Robert Jr. took over the Wisconsin Republican Party, later founding the
Wisconsin Progressive Party as a successor to
their father's Progressive Party. It gained momentum in the mid-1930s with support from President
Franklin D. Roosevelt and progressive Democrats, winning offices statewide and in Congress. The party declined after Philip, facing scandal and accusations of authoritarianism,
lost reelection in 1938 to
Julius P. Heil and left politics to serve in
World War II. The
National Progressives of America, an organization Philip had hoped would precede a national realignment, then faltered. The last Progressive candidate elected governor of Wisconsin was
Orland S. Loomis, elected in the
1942 gubernatorial election, he would die before taking office. Resulting in the
Wisconsin Supreme Court installing Republican
Walter S. Goodland to serve Loomis's term as governor. The Wisconsin Progressives eventually voted to dissolve and rejoin the republican party in 1946.
Mid-20th century to present In World War II's immediate aftermath, Wisconsinites were divided over issues such as the creation of the
United Nations, support for the European recovery, and the growth of the
Soviet Union's power. But when
Europe divided into Communist and capitalist camps, and with the Progressive Party's collapse,
Robert La Follette Jr. rejoined the Republican Party of Wisconsin to run in the 1946 Senate election. He narrowly lost to
Joseph McCarthy in the
Republican primary. After the
Chinese Communist Revolution of 1949, public opinion began to continue move toward support for the protection of democracy and capitalism against Communist expansion. was a major hub for shipping iron ore across the Great Lakes via
lake freighters. Wisconsin took part in several political extremes in the mid- to late 20th century, ranging from the
anti-communist crusades of Senator McCarthy in the 1950s, to the founding of
Earth Day by environmental advocate
Gaylord Nelson in 1970. During radical protests against the
Vietnam War at UW-Madison, an attack by anarchists culminated in the
Sterling Hall bombing in August 1970. The state undertook
welfare reform under Republican Governor
Tommy Thompson during the 1990s. Its economy also underwent further transformations toward the end of the 20th century, as heavy industry and manufacturing declined in favor of a
service economy based on medicine, education, agribusiness, and tourism. In 2011, Wisconsin became the focus of some controversy when newly elected governor
Scott Walker proposed and then passed and enacted
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 protest to the changes, and Walker survived
a recall election held the next year in 2012, becoming the first governor in U.S. history to do so. Also in 2012, Congressman
Paul Ryan became the first Wisconsinite to appear on a major party ticket, as Republican nominee
Mitt Romney's running mate in the
2012 United States presidential election. Ryan was elected
Speaker of the House in 2015. Since 2023,
five University of Wisconsin branch campuses have closed, one has gone entirely online, and one has stopped using several of its buildings. Many have expressed concern about the Wisconsin Idea's future since these closures. ==Geography==
