Fort Laramie is one of the most important historic sites in Wyoming, in part because its original buildings are extremely well preserved, but also because it played a role in several significant periods in Western history. Near the confluence of the Laramie and North Platte rivers, the fort began as a trading post in 1834, and it was an important provisioning point for travelers on the Oregon Trail in 1843, the Mormon Trail in 1847, and the California Trail in 1849, when
it also became a military site. In 1851 the first treaty between the U.S. government and the Northern Plains Indians was negotiated near the fort, and in 1868 a second Fort Laramie Treaty led to the end of the First Sioux War, also known as Red Cloud's War. Costumed interpreters reenact scenes of military life and talk about the fur trade, overland migration, and relations between settlers and Native Americans.
