Thomas Jefferson

Head of state or government

Thomas Jefferson was a Founding Father and the third president of the United States, serving from 1801 to 1809. From 1797 to 1801, he served as the second vice president under John Adams. A prolific writer and philosopher, Jefferson was the primary author of the Declaration of Independence. His political philosophy, defined by republicanism, individual liberty, agrarianism, and limited government, formed the basis for Jeffersonian democracy. While he remains celebrated as an icon of American political values, Jefferson is also controversial for having enslaved more than 600 people.
