Benjamin Banneker challenges Jefferson on slavery and racial equality

Maryland; letter to Secretary of State Thomas Jefferson

Benjamin Banneker sent Jefferson a manuscript almanac and argued against racial prejudice. Invoking the Declaration’s equality principle and the colonists’ struggle against oppression, he challenged Jefferson’s participation in enslaving other people. His scientific work accompanied a direct appeal to recognize Black people’s humanity and abilities.

Context / qualification

This was advocacy, not a law or emancipation decree. Banneker assisted Andrew Ellicott in the preliminary survey of the federal territory; that work should not be inflated into authorship of Washington’s city plan.
