George Washington left Philadelphia in 1793 primarily to return to Mount Vernon, his plantation in Virginia, after a busy winter session of Congress. His departure was also influenced by the need to address personal matters and the management of his estate. Additionally, the political tensions of the time, especially regarding issues like the French Revolution, may have contributed to his desire to step back from the political scene temporarily. Washington's retreat to Mount Vernon emphasized his commitment to balancing public service with his private life.
