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.
