The history of Wisconsin encompasses the story not only of the people who have lived in Wisconsin since it became a state of the U.S., but also that of the Native American tribes who made their homeland in Wisconsin, the French and British colonists who were the first Europeans to live there, and the American settlers who lived in Wisconsin when it was a territory.
Since its admission to the Union on May 29, 1848, as the 30th state, Wisconsin has been ethnically heterogeneous, with Yankees being among the first to arrive from New York and New England. They dominated the state's heavy industry, finance, politics and education. Large numbers of European immigrants followed them, including German Americans, mostly between 1850 and 1900, Scandinavians (the largest group being Norwegian Americans) and smaller groups of Belgian Americans, Dutch Americans, Swiss Americans, Finnish Americans, Irish Americans and others; in the 20th century, large numbers of Polish Americans and African Americans came, settling mainly in Milwaukee, as well as Hmong Americans in Eau Claire and Appleton.
Politically the state was predominantly Republican until recent years, when it became more evenly balanced. The state took a national leadership role in the Progressive Movement, under the aegis of Robert M. "Fighting Bob" La Follette and his family, who fought the old guard bitterly at the state and national levels. The "Wisconsin Idea" called for the use of the higher learning in modernizing government, and the state is notable for its strong network of state universities.
