The western frontier in Thomas Jefferson's lifetime moved from the nearby Appalachian Mountains during his childhood to the Pacific Ocean during his presidency. Although Jefferson himself only went as far west as Falling Spring Falls, Virginia, near the present West Virginia border, he became one of America's strongest advocates for western exploration.
Jefferson's initial overture for a western exploratory party was directed to Revolutionary War hero George Rogers Clark. He began his 1783 letter to Clark with the two topics that pulled his thoughts westward: science and politics. He thanked Clark for sending him shells and seeds and assured him that he would be pleased to have as many bones, teeth, and tusks of the mammoth as Clark might be able to find. Within the same paragraph, Jefferson then revealed his apprehension at the rumor that money was being raised in England for exploration between the Mississippi and the Pacific, fearing the actual intent was colonization. Jefferson then wondered, if money could be raised in this country for western exploration, "How would you like to lead such a party?"
Clark declined Jefferson's request for financial reasons. However, as a hero of the western theater of the Revolution he was quite knowledgeable of the American Indians of the northwest territory. He offered advice on how to best proceed among the Indian peoples, advice which Jefferson stored away for future use. In later correspondence Clark recommended his youngest brother, William, as also knowledgeable of the Indian territory and "well qualified almost for any business."
While in Paris as minister to France, Jefferson joined in a plan for an American explorer named John Ledyard to cross Russia, obtain water passage to some point on the North American coast, and explore from the Pacific eastward. Jefferson supported the venture but noted that despite Ledyard's ingenuity and information, "Unfortunately he has too much imagination." Having embarked on his trip across Russia, Ledyard was was arrested within 200 miles of Kamschatka, accused of being a French spy, escorted to the Polish border, and charged not to set foot within Russian territory again.
A more promising endeavor was initiated by Jefferson and fellow members of the American Philosophical Society in 1793. They enlisted French botanist André Michaux "to explore the country along the Missouri, & thence Westwardly to the Pacific ocean." Jefferson organized the subscription to finance the expedition, and even though the undertaking was not under government sponsorship, he appraised President Washington, who offered to "readily add my mite" to the project. Jefferson's instructions to Michaux on behalf of the Society reiterated the objective of finding the shortest route to the Pacific, with equal importance given to the gathering of geographic and scientific data. But the expedition began to unravel before reaching the Mississippi River, as it became apparent that Michaux was involved in a French plot to gather support against the Spanish settlements west of the Mississippi. An important remnant of this truncated expedition was Jefferson's written set of instructions to Michaux, which would reappear in a more detailed form when delivered later to Meriwether Lewis.
These failed attempts undoubtedly added to Jefferson's store of information on western exploration, and when circumstances placed him in a key position to act, he was prepared to do so quickly and decisively. In his first inaugural address in 1801 Jefferson envisioned "[a] rising nation, spread over a wide and fruitful land, advancing rapidly to destinies beyond the reach of mortal eye." Less than two years later, on January 18, 1803, he would deliver a confidential message to Congress outlining a plan for exploring to the "Western Ocean," and requesting an appropriation of $2,500 for what would become the Lewis and Clark Expedition. In May 1804, as Lewis and Clark were poised to begin pushing westward along the Missouri River, Jefferson must have felt more confidence in seeing his western desideratum fulfilled, writing: "We shall delineate with correctness the great arteries of this great country: those who come after us will fill up the canvas we begin."
Jefferson and the West: A Chronology
Jefferson's Early Exposure to -€˜The West'
1749: Thomas Jefferson's father, Peter Jefferson, is one of the founding members of the Loyal Company, created to petition for grants of land west of the Allegheny Mountains. Other founding members are Joshua Fry, Thomas Walker, James Maury, and Thomas Meriwether, Meriwether Lewis' grandfather.
1751: Joshua Fry and Peter Jefferson complete their "Map of the Most Inhabited Part of Virginia Containing the Whole Province of Maryland," the first map of Virginia created from actual surveys.
1753: The Loyal Company plans an exploratory expedition up the Missouri River led by Thomas Walker, but abandons the enterprise due to the outbreak of the French and Indian War. Jefferson is 10 years old at this time.
1758-60: Following his father's death, Jefferson attends the boarding school of Rev. James Maury, who as a member of the Loyal Company was involved in the planning of the proposed western expedition.
1780s: In his Notes on the State of Virginia, Jefferson includes the Missouri, other western rivers, and points on western geography even though the Treaty of Paris of 1763 excluded the western territory as a part of Virginia.
Proposed Western Expeditions Before Lewis and Clark
1783: Jefferson approaches George Rogers Clark to lead an expedition to explore the West, provided the money can be raised. Clark declines, but suggests his youngest brother, William, "as well qualified almost for any business."
1784: Jefferson introduces in Congress the Ordinance of 1784, which set forth the principle that new states could be formed from the western territories and admitted to the Union on an equal basis with the original states.
1786: While minister to France, Jefferson joins in a plan to support American explorer John Ledyard to travel eastward across Siberia, secure passage of a ship to some point on the western coast of North America, then travel east across the continent. Ledyard, however, is arrested in Russia and sent back to Europe.
1793: Jefferson enlists other members of the American Philosophical Society to sponsor André Michaux, a French botanist to "find the shortest & most convenient route of communication between the U.S. & the Pacific Ocean." But the expedition is abandoned east of the Mississippi because of political intrigues.
