About 100 slaves lived and worked at Monticello at any given time. They plowed the fields, planted the wheat, and drove the wagons. They cared for the hogs and cows. Household slaves prepared food for Thomas Jefferson and his family. They washed his clothes and cared for his children. Despite writing the words "all men are created equal," Jefferson was a life-long slave owner who held over 600 humans in bondage throughout his lifetime.
