Jefferson faced opposition from his own party .
As mentioned earlier, Jefferson had .
an interest in North American exploration. He used his presidential .
power to purchase Louisiana from France and gave Meriwither Lewis and .
William Clark the opportunity and the responsibility to explore this .
vast territory. After their triumphant return, the hostile Aaron Burr .
engaged in a conspiracy either to establish an independent republic in .
the Louisiana Territory or to launch an invasion of Spanish-held .
Mexico. Jefferson acted promptly to arrest Burr and brought him to .
trial for treason. Burr was acquitted, however. Foreign policy during .
his second term was rather unsuccessful. In an effort for the British .
to respect the United States" neutrality during the Napoleonic Wars by .
passing the Embargo Act, he persuaded Congress to stop all trade with .
Britain, a move that failed to gain any respect from Britain, .
alienated New England (who lived by foreign trade), and shattered the .
nation's economy. Fifteen months later, he repealed the Embargo Act. .
In the final years of his life, Jefferson's major accomplishment was .
the founding of the University of Virginia at Charlottesville. He .
conceived it, planned it, designed it, and supervised both its .
construction and the hiring of the workers. He also hired the first .
professors and came up with its first course of study. .
Jefferson wished to be remembered by three things, which .
consisted of a trilogy of unrelated causes: freedom from Britain, .
freedom from conscience, and freedom maintained through education. On .
the 50th anniversary of the Declaration of Independence, Jefferson .
died in Monticello. Though not flawless, given Jefferson's .
contributions to the shaping of American society then and how it is .
today, it is nearly impossible to find him morally weak and coarse. .
He has truly defined true American culture as it is today and has .
shaped the lives of many Americans both of his time and our time .
