Wisconsin

Wisconsin entered the Union on May 29, 1848 as the 30th state. Wisconsin grew from the old Northwest frontier into a state shaped by immigration, manufacturing, labor activism, dairy farming, and a nationally influential reform tradition. Today its state government is centered in Madison and follows the bicameral model with a governor, a Senate, and an Assembly.
