This area was part of Wisconsin Territory until the eastern part of that territory achieved statehood in 1848. Brown and other leaders called a meeting (the "Stillwater Convention") on August 26, 1848. The convention drafted a Memorial to Congress that a new territory be created with the name “Minnesota,” and elected Henry Hastings Sibley to deliver this citizens' petition to the U.S. Congress. Because of this convention, Stillwater calls itself the “Birthplace of Minnesota.” Congress responded by creating Minnesota Territory effective March 3, 1849.
