Letter to John Adams, 1815

”

From Declaration to Presidency

A quarter-century after writing the Declaration of Independence, Jefferson won the contested 1800 election, defeating the incumbent John Adams and ending Federalist control of the presidency for a generation.

The Louisiana Purchase

Jefferson's presidency is defined most by a single transaction: in 1803, he purchased roughly 828,000 square miles of French territory for $15 million, doubling the size of the United States overnight. The purchase created a real constitutional problem Jefferson himself worried about — nothing in the Constitution explicitly authorized the federal government to acquire new territory this way — but he moved forward regardless, prioritizing the strategic and economic opportunity over strict constitutional literalism.

Neutrality Amid European War

Much of Jefferson's second term was consumed trying to keep the United States out of the wars between France and Britain, an increasingly difficult balancing act as both powers interfered with American shipping.

Retirement, Reconciliation, and a Remarkable Death

After leaving office, Jefferson retired to Monticello, continued advising Madison and Monroe, and in 1819 founded the University of Virginia, personally designing its campus and curriculum. In 1824, he and Adams — once close friends, then bitter political rivals, then reconciled correspondents in old age — exchanged letters reflecting on the nation they'd both helped build. Jefferson died on July 4, 1826, the 50th anniversary of the Declaration of Independence, within hours of John Adams himself — Adams's last words were reportedly "Thomas Jefferson survives," not knowing Jefferson had already died that same day.
