Upon leaving the Great Falls of the Missouri on July 15, 1805, the Lewis and Clark expedition began to search in earnest for the Shoshone from whom they hoped to purchase horses for their journey over the Rockies. The next day, Lewis identified an abandoned but recent Shoshone camp with a wickiup and signs of numerous horses, but the Indians remained elusive. The captains decided to split up and have Clark take a detachment ahead while Lewis brought up the boats and the rest of the Corps.

As Lewis and Clark continued their journey up the Missouri River in 1805, the Corps was moving further and further from civilization with every stroke of their paddles. Although the Corps had been made aware of the countless wonders to the west through conversations with the Mandans and Hidatsas, it was quite another thing to observe the wonders for themselves, and at seemingly every bend in the river there were new discoveries.

The Corps of Discovery arrived at the Mandan villages near present day Bismarck, North Dakota, in late October 1804 and prepared to settle in for the long winter. For the past five months, the Lewis and Clark expedition had spent most days rowing or pushing their keelboat against the Missouri River’s powerful current, and the men were ready for a break. They were now 1,300 river miles upstream from the nearest civilized settlement and, although they did not know it, they had over 2,000 miles to go to reach the Pacific Ocean.

On August 31, 1803, Captain Meriwether Lewis departed from Fort Fayette, today’s Pittsburgh, in the keelboat the Corps of Discovery would take up the Missouri River and, six weeks later, arrived at the Falls of the Ohio and Clarksville, Indiana Territory. It was here, at the town founded by General George Rogers Clark, that Meriwether Lewis and William Clark, the General’s youngest brother, met again for the first time in seven years and commenced the most famous partnership in American history, two men so joined in American lore as to almost be inseparable. 

In 1801, Meriwether Lewis was a Captain serving as the paymaster for the First Infantry Regiment of the United States Army. In March, he received a letter from Thomas Jefferson, the newly inaugurated President, asking Lewis to become his private secretary. Lewis, whose family was friends with the Jefferson clan, accepted at once, and thus began a close working relationship, one in which Jefferson became a father figure to Lewis and mentored his young subordinate on policy matters, including his dreams of western exploration and expansion.

By the time they began to assemble the Corps of Discovery in the summer of 1803, Thomas Jefferson and Meriwether Lewis knew more than anyone else about the Louisiana Territory, that immense wilderness the country had recently purchased from France. Although Jefferson had never ventured more than fifty miles west from Monticello, he had dreamed of the trans-Mississippi and studied the region extensively over the previous two decades, even trying unsuccessfully to send exploratory expeditions on several occasions.

The dream of finding an all water route across North America, the mythical Northwest Passage, had been imagined since the time of Christopher Columbus. Incredibly, three hundred years after the Admiral of the Ocean Seas completed his epic voyages, the vast interior of the continent was still essentially unknown to Europeans. This great uncertainty led to numerous theories about what lay beyond what men could see.

The midnight deal Robert Livingston, United States Minister to France, struck with Francois Barbe-Marbois, Napoleon’s Finance Minister, on April 13, 1803, to purchase the Louisiana territory was one of the most impactful agreements in the history of the United States. It resulted from months of conversations Livingston had had with numerous French officials, creating a foundation for the details that would follow. But as important as this step was, there remained several hurdles to overcome.

As a boy growing up in Virginia, Thomas Jefferson listened to his father tell captivating stories of the pristine wilderness beyond the Appalachian Mountains and dreamed of what opportunities lay in the uncharted lands of North America. As Jefferson grew to manhood, he became a proponent of national expansionism, recognizing that the future greatness of the country lay outside the original thirteen colonies.

The Treaty of Paris of 1783 which officially ended the American Revolution was generous to the United States, much more so than most had expected. Besides recognizing American independence, the provisions which Great Britain proposed greatly expanded the boundaries of the new nation, granting the United States all the land north of the Ohio River as far west as the Mississippi and as far north as British Canada. But like all gifts from adversaries, this one came with some issues that would simmer for decades.

The Louisiana Purchase of 1803 was one of the truly watershed events in American history. The acquisition of this vast land placed the United States firmly on a path towards both the domination of North America and the status of an emerging world power.

On May 15, 1776, the fifth Virginia Convention meeting in Williamsburg passed a resolution calling on their delegates at the Second Continental Congress to declare a complete separation from Great Britain. Accordingly, on June 7, Richard Henry Lee rose and introduced into Congress what has come to be known as the Lee Resolution.

Thomas Jefferson’s revolutionary journey began in the 1760s and culminated in his masterfully written Declaration of Independence in 1776. But in between these events, Jefferson crafted one of the most impactful statements ever for American independence. Entitled A Summary View of the Rights of British America, it was perhaps the most logical assessment of the true relationship between Great Britain and her American colonies. The concepts Jefferson laid out had been refined and brought into focus following several dustups with Lord Dunmore, the new Royal Governor.

In 1765, Parliament passed the Stamp Act, the first internal tax on the American colonies, and thus began a decade of missteps by the British. Their miscalculations would take their country and their colonists on a direct path to Lexington Green and Concord Bridge on April 19, 1775. During this same year, Thomas Jefferson was concluding his time studying law under George Wythe and began to turn his eye towards the world at large and, more specifically, politics in the Colony of Virginia.

Thomas Jefferson is one of America’s most iconic Founding Fathers. Best known for his inspirational words in the Declaration of Independence, Jefferson was a brilliant man with diverse interests who spent the bulk of his life in service to his country and his later years in retirement at his beloved mountain home of Monticello, near Charlottesville, Virginia.

The presidential election of 1800 ended in a tie, as the two Democratic-Republican candidates, Thomas Jefferson and Aaron Burr, each received 73 electoral votes under the original guidelines of the Constitution.

The Presidential election of 1800 was one of the most controversial and consequential in the history of the United States. It represented a true changing of the guard as the Federalist party of Washington, Hamilton, and Adams gave way to the Democratic-Republican ideals of Jefferson and Madison and took the United States in a different direction for a generation to come.

John Adams’s loss to Thomas Jefferson in the presidential election of 1800 was a great disappointment for Adams as he felt he deserved another term based on his accomplishments during his four years as President. But Adams accepted the verdict of the Electoral College and looked forward to the next phase of his life.

The only fighting in the Quasi-War occurred at sea, and mostly in the Caribbean. But with war at a fever pitch and French interests so close by in Louisiana, there was a very real concern in Congress about a possible French invasion of the United States from the west. 

Between 1798 and 1800, the United States fought an undeclared war with France called the Quasi-War, or Half War, because it was not formally recognized by Congress. It was largely a naval conflict fought in the Caribbean and southern coast of America and developed because of a series of related events that soured the formerly strong relationship between the two nations.
