Welcome to Wyoming - the Equality State
Wyoming Territory was formed July 25, 1868 primarily from Dakota Territory, with parts of Idaho and Utah Territories included. Wyoming was admitted to the Union as the 44th state July 10, 1890.
Until 1811, when fur traders first opened a trail through the area, Wyoming was the domain of the American Indians. Between 1825 and 1840, about 200 mountain men bartered with the Indians at rendezvous in the region. In the 1840s and 1850s, many thousands of emigrants traveling the Oregon Trail to California, Utah, and other western states passed through the North Platte and Sweetwater valleys and South Pass in central Wyoming.

Before visiting individual courthouses it is important to check the holdings of the State Archives as a considerable amount of 19th and 20th century county records have been moved to Cheyenne. The on-line website for the Archives is a valuable tool in planning your research in Wyoming. Microfilmed records in the archives may be researched with MARSS.
Wyoming currently has 23 counties. The earliest county was created in 1867 and the last were created in 1921. Two counties were created as Carter and Pease and later had their names changed to Sweetwater and Johnson, respectively.
