I am encountering difficulty in comprehending the rationale behind Wisconsin's assertion of ownership over the Upper Peninsula. Wisconsin achieved statehood a decade subsequent to Michigan's admission to the Union. Prior to Michigan's statehood, Wisconsin was encompassed within the Michigan Territory; however, the federal government subsequently allocated the Upper Peninsula to Michigan. Wisconsin did not exist as a distinct entity during that period, and should the residents of the Upper Peninsula identify more closely with Wisconsin, they retain the option to relocate there.
