Because of Wyoming's location at the intersection of the Louisiana Purchase, the Oregon Country, and the Mexican Cession, the land which became Wyoming has a complicated history of territorial relationships. Portions of the territory which eventually fell under Wyoming's jurisdiction were at various points associated with the territories of Washington, Oregon, Idaho, Dakota, Nebraska, and Utah, and had previously belonged to the independent states of Great Britain, France, Spain, Mexico, and Texas.

The portion of the Wyoming Territory east of the Nebraska Territory in 1854. On March 2, 1861, the northern portion of the Nebraska Territory, including the northeastern portion of future Wyoming Territory became part of the Dakota Territory, while the southeastern portion remained with Nebraska, forming an extended Nebraska "panhandle" which included the settlement of Cheyenne. In 1863, the Idaho Territory was formed; it included the entirety of the modern states of Idaho and Montana and almost all of modern Wyoming save the southwest corner.

The portion of the Wyoming Territory west of the continental divide and north of the 42nd parallel was originally part of the Oregon Territory in 1848; when Oregon entered the union as a state under its present boundaries in 1859, this land became part of the Washington Territory (although its eastern part had been granted to the Nebraska Territory in 1854 (right). The Idaho Territory subsumed this land as well in 1863.

The southwestern corner of what became the Wyoming Territory, south of the 42nd parallel, became part of the United States with the 1848 Colorado Territory in 1861, most of it was transferred to the Nebraska Territory (left) and subsumed into the Idaho Territory in 1863. A small corner of Wyoming remained part of Utah until the creation of the Wyoming Territory in 1868.

1864 partition of the Idaho Territory. The blue area became part of Dakota Territory, and later part of Wyoming Territory

In 1864, with the formation of the Montana Territory, the southeastern section of the Idaho Territory (most of modern Wyoming) became briefly part of Dakota Territory once again (right), although a strip of land along the western border of what would become Wyoming remained part of the Idaho Territory.


1868 partition of the Utah Territory

The Territory of Wyoming was created by Act of Congress on July 25, 1868. At the time of its formation, it took land from the Dakota, Idaho, and Utah Territories. In 1872, Wyoming Territory had five counties: Albany, Carbon, Laramie, Sweetwater, and Uinta, each a tall narrow rectangle comprising approximately one-fifth of the territory.[1]

The territory was admitted to the Union as the 44th state on July 10, 1890.
