In the thick of party conflict in 1800, Thomas Jefferson wrote in a private letter, "I have sworn upon the altar of God eternal hostility against every form of tyranny over the mind of man."
This powerful advocate of liberty was born in 1743 in Albemarle County, Virginia, inheriting from his father, a planter and surveyor, some 5,000 acres of land, and from his mother, a Randolph, high social standing. He studied at the College of William and Mary, then read law. In 1772 he married Martha Wayles Skelton, a widow, and took her to live in his partly constructed mountaintop home, Monticello.
Freckled and sandy-haired, rather tall and awkward, Jefferson was eloquent as a correspondent, but he was no public speaker. In the Virginia House of Burgesses and the Continental Congress, he contributed his pen rather than his voice to the patriot cause. As the "silent member" of the Congress, Jefferson, at 33, drafted the Declaration of Independence. In years following he labored to make its words a reality in Virginia. Most notably, he wrote a bill establishing religious freedom, enacted in 1786.
