Wisconsin Territory
Originally part of the Michigan Territory, the Wisconsin Territory became a separate political entity on July 3, 1836. The territory originally included all of the modern states of Wisconsin, Minnesota, and Iowa, along with parts of North and South Dakota. In 1838, all but the current state of Wisconsin and an eastern portion of Minnesota were removed to become Iowa Territory. The Wisconsin Territory maintained those boundaries until May 29, 1848, when Wisconsin achieved statehood. The territorial capital was briefly at Belmont but soon relocated to Madison.
