John Hanson was an American Founding Father, merchant, and politician from Maryland during the Revolutionary Era. In 1779, Hanson was elected as a delegate to the Continental Congress after serving in a variety of roles for the Patriot cause in Maryland. He signed the Articles of Confederation in 1781 after Maryland joined the other states in ratifying them. In November 1781, he was elected as the first President of the Confederation Congress, following ratification of the articles. For this reason, some of Hanson's biographers have argued that he was actually the first holder of the office of President of the United States.
