11 May - Minnesota became a state of the United States in 1858

 

Minnesota became a state of the United States on May 11, 1858. Prior to that, it was a territory under the control of the United States government. The United States acquired the area through the Louisiana Purchase in 1803, and it was initially part of the larger Northwest Territory. Over time, the region was organized into various territories, including the Minnesota Territory, before eventually achieving statehood. The process of becoming a state involved the drafting of a state constitution and approval by the U.S. Congress. Minnesota's admission as the 32nd state of the United States marked its formal incorporation into the Union.
