Wisconsin State Flower - Wood Violet
The area of Wisconsin was part of the original territory of the United States, being part of lands ceded by four states to the United States and designated in 1787 as the “Territory northwest of the River Ohio.” Wisconsin Territory was organized on July 3, 1836, from part of Michigan Territory; it included all of present-day Wisconsin, Iowa, and Minnesota, eastern North Dakota and South Dakota, and a small part of northeastern Nebraska. The territory was reduced in 1838 with the organization of Iowa Territory west of the Mississippi River and a line northward from the river’s source.
Although the territory had not yet been legally established, census data for Wisconsin are available beginning with the 1820 census. The 1840 census population is for the entire territory, including the portion of Minnesota northeast and east of the Mississippi River and a line northward from the river’s source. For an explanation of the revision to the 1820 and 1830 population of Wisconsin, see Richard L. Forstall, Population of States and Counties of the United States: 1790- 1990, Washington, DC: U.S. Government Printing Office, 1996, page 184.
Data for the legally established state of Wisconsin are available beginning with the 1850 census.
