caption_attribution_description: English: Founded by William Sublette and Robert Campbell, Fort Laramie lay at the crossroads of an old north-south Indian trail and what became known as the Oregon Trail. Called Fort Laramie because of the nearby Laramie Mountains and the Laramie Fork of the North Platte River, the post was approximately 150 feet square, according to Miller, with bastions at the diagonal corners. Miller's paintings are the only known visual records of the fort, because the original fort was torn down in 1840 before any other artist had traveled the Oregon Trail; it was replaced with another structure, located perhaps on the same site in 1841.
context_page_description: The American frontier includes the geography, history, folklore, and cultural expression of life in the forward wave of American expansion that began with English colonial settlements in the early 17th century and ended with the admission of the last remaining western territories as states in 1912. This era of massive migration and settlement was particularly encouraged by President Thomas Jefferson following the Louisiana Purchase, giving rise to the expansionist philosophy known as "Manifest Destiny" and the frontierist "Frontier Thesis".
  A frontier is a zone of contact at the edge of a line of settlement. Leading theorist Frederick Jackson Turner went deeper, arguing that the frontier was the defining process of American civilization: "The frontier," he asserted, "promoted the formation of a composite nationality for the American people." He theorized it was a process of development: "This perennial rebirth, this fluidity of American life, this expansion westward...furnish[es] the forces dominating American character."
context_section_description: Government and private enterprise sent many explorers to the West. In 1805–1806, Army lieutenant Zebulon Pike (1779–1813) led a party of 20 soldiers to find the headwaters of the Mississippi. He later explored the Red and Arkansas Rivers in Spanish territory, eventually reaching the Rio Grande. On his return, Pike sighted the peak in Colorado named after him. Major Stephen Harriman Long (1784–1864) led the Yellowstone and Missouri expeditions of 1819–1820, but his categorizing in 1823 of the Great Plains as arid and useless led to the region getting a bad reputation as the "Great American Desert", which discouraged settlement in that area for several decades.
  In 1811, naturalists Thomas Nuttall (1786–1859) and John Bradbury (1768–1823) traveled up the Missouri River documenting and drawing plant and animal life. Artist George Catlin (1796–1872) painted accurate paintings of Native American culture. Swiss artist Karl Bodmer made compelling landscapes and portraits. John James Audubon (1785–1851) is famous for classifying and painting in minute details 500 species of birds, published in Birds of America.
  The most famous of the explorers was John Charles Frémont (1813–1890), an Army officer in the Corps of Topographical Engineers. He displayed a talent for exploration and a genius at self-promotion that gave him the sobriquet of "Pathmarker of the West" and led him to the presidential nomination of the new Republican Party in 1856. He led a series of expeditions in the 1840s which answered many of the outstanding geographic questions about the little-known region. He crossed through the Rocky Mountains by five different routes and mapped parts of Oregon and California. In 1846–1847, he played a role in conquering California. In 1848–1849, Frémont was assigned to locate a central route through the mountains for the proposed transcontinental railroad, but his expedition ended in near-disaster when it became lost and was trapped by heavy snow. His reports mixed narrative of exciting adventure with scientific data and detailed practical information for travelers. It caught the public imagination and inspired many to head west. Goetzman says it was "monumental in its breadth, a classic of exploring literature".
  While colleges were springing up across the Northeast, there was little competition on the western frontier for Transylvania University, founded in Lexington, Kentucky, in 1780. It boasted of a law school in addition to its undergraduate and medical programs. Transylvania attracted politically ambitious young men from across the Southwest, including 50 who became United States senators, 101 representatives, 36 governors, and 34 ambassadors, as well as Jefferson Davis, the president of the Confederacy.
