George Washington was sworn in as the first President of the United States in New York City in 1789. He was concerned about his lack of experience but felt it was his duty to serve. As the first President, Washington established many precedents for the office, including creating executive departments like Treasury, State, and War and nominating the first Cabinet members. The Judiciary Act of 1789 also established the first federal court system with district courts, courts of appeal, and the Supreme Court, with John Jay as the first Chief Justice.
