 All of the land east of the Mississippi River was granted to the United States by the Second Treaty of Paris at the end of the American Revolution in 1783 . This included what would become modern day Saint Paul but only part of Minneapolis , including the northeast , north @-@ central and east @-@ central portions of the state . The wording of the treaty in the Minnesota area depended on landmarks reported by fur traders , who erroneously reported an " Isle Phelipeaux " in Lake Superior , a " Long Lake " west of the island , and the belief that the Mississippi River ran well into modern Canada . Much of this region was claimed by other states who subsequently ceded these to the federal government .
