The U.S. acquired the land comprising Wyoming from France as part of the Louisiana Purchase in 1803. John Colter, a fur-trapper, is the first white man known to have entered the region. In 1807 he explored the Yellowstone area and brought back news of its geysers and hot springs.
Robert Stuart pioneered the Oregon Trail across Wyoming in 1812–1813 and, in 1834, Fort Laramie, the first permanent trading post in Wyoming, was built. Western Wyoming was obtained by the U.S. in the 1846 Oregon Treaty with Great Britain and as a result of the treaty ending the Mexican War in 1848.
When the Wyoming Territory was organized in 1869, Wyoming women became the first in the nation to obtain the right to vote. In 1925 Mrs. Nellie Tayloe Ross became the first woman governor in the United States.
Wyoming's towering mountains and vast plains provide spectacular scenery, grazing lands for sheep and cattle, and rich mineral deposits.

A leading producer of sheep and wool, Wyoming is also a major producer of beef cattle and hogs. Principal crops include wheat, oats, sugar beets, corn, barley, and alfalfa.

Wyoming was selected as an official state of the Free State Project, a political migration. The plan was to have all Libertarians relocate to one state so they could live free. The project was started in 2001. Members voted on select states for the migration. Wyoming received 498 votes, coming in second behind New Hampshire.
