This course presents Thomas Jefferson as neither a flawless republican hero nor a figure reducible to his failures. Beginning with colonial Virginia’s landed society, tobacco economy, slavery, and classical education, it follows the intellectual, personal, and political formation that carried him into law, revolution, and authorship of the Declaration of Independence. The course examines his legislative reforms, wartime governorship, scientific and political writing, diplomacy in France, cabinet conflicts, opposition leadership, and two presidential terms. Across these settings, it analyzes Jefferson’s arguments about natural rights, religious liberty, federalism, executive authority, education, and republican government alongside moments when necessity, ambition, or policy strained those principles. His relationships, slaveholding, spending, debts, family life, and work at Monticello and the University of Virginia reveal further tensions between accomplishment and consequence. The concluding perspective considers how Jefferson cultivated his legacy and why later generations have repeatedly reinterpreted it.
