His masterpiece, the Declaration of Independence (1776), remains among the most celebrated documents in history, proclaiming that "all men are created equal" and endowed with unalienable rights. His only full-length book, Notes on the State of Virginia (1785), offered a rich account of his home state's geography, laws, and society while revealing his complex views on slavery. Earlier, his pamphlet A Summary View of the Rights of British America (1774) established him as a bold voice for colonial rights.
Jefferson also authored the Virginia Statute for Religious Freedom (1786), a landmark in the separation of church and state, and his vast correspondence, particularly with John Adams, is treasured as essential American writing. In 1819, he founded the University of Virginia, designing both its curriculum and architecture. Jefferson died on July 4, 1826, exactly fifty years after the Declaration's adoption.
