Thomas Jefferson – Biography, Contradictions, and Legacy

Thomas Jefferson was a Founding Father, the principal author of the Declaration of Independence, the third U.S. president, and a highly influential but deeply contradictory figure whose legacy includes both democratic ideals and slaveholding. Born into Virginia’s planter class, he helped shape the nation’s founding principles while owning hundreds of enslaved people throughout his life.

Jefferson’s career spanned the drafting of America’s birth certificate, a fierce political rivalry that created the two-party system, and a presidency that doubled the nation’s size.
