Thomas Jefferson (April 13 [O.S. April 2] 1743 – July 4, 1826) was an American Founding Father who was principal author of the Declaration of Independence (1776). He was elected the second Vice President of the United States (1797–1801) and the third President (1801–09). Jefferson was a proponent of democracy, republicanism, and individual rights, which motivated American colonists to break from Great Britain and form a new nation. He produced formative documents and decisions at both the state and national level.
