During the president’s two terms in office, the Washingtons relocated first to New York and then to Philadelphia. Although slavery had steadily declined in the North, the Washingtons decided that they could not live without it. Once settled in Philadelphia, Washington encountered his first roadblock to slave ownership in the region — Pennsylvania’s Gradual Abolition Act of 1780.
The act began dismantling slavery, eventually releasing people from bondage after their 28th birthdays. Under the law, any slave who entered Pennsylvania with an owner and lived in the state for longer than six months would be set free automatically. This presented a problem for the new president.
Washington developed a canny strategy that would protect his property and allow him to avoid public scrutiny. Every six months, the president’s slaves would travel back to Mount Vernon or would journey with Mrs. Washington outside the boundaries of the state. In essence, the Washingtons reset the clock. The president was secretive when writing to his personal secretary Tobias Lear in 1791: “I request that these Sentiments and this advise may be known to none but yourself & Mrs. Washington.”
