No, he was not. The confusion came from two aspects. First, John Hanson, the first president of the Continental Congress is often considered the first president of the Unites States, but this is not true, since the position was created only 6 years after he died. Second, the claim that he was actually a black man comes from the fact that some people used an anachronistic photograph of Senator John Hanson of Liberia to represent him.
John Hanson, the first president of the Continental Congress under the Articles of Confederation, dies in his home state of Maryland on November 22, 1783. He is sometimes called the first president of the United States, but this is a misnomer, since the presidency did not exist as an executive position separate from Congress until the federal Constitution created the role upon its ratification in 1789.
The first president of the United States was George Washington,who was inaugurated on April 30, 1789, taking the oath of office at Federal Hall in New York City. As everyone knows, he was a white man.
