Who was the first President of the United States?

The President of the United States of America (often abbreviated POTUS) is the head of state of the United States. The office of President was established upon the ratification of the United States Constitution in 1788 and the first president took office in 1789. The President serves as chief executive and head of the executive branch of the United States government. Article Two of the United States Constitution establishes the President as the Commander-in-Chief of the armed forces and enumerates powers specifically granted to the President, including the power to sign into law bills passed by both houses of the Legislature, to create a Cabinet of advisors, to grant pardons or reprieves, and, with the "advice and consent" of the United States Senate, to make treaties and appoint Officers, Ambassadors, Judges, and Justices of the Supreme Court. Article Two also defines a Presidential term at four years; subsequently, the Twelfth Amendment (1804) revised the procedure for electing the President and the Twenty-second Amendment (1951) established Presidential term limits.
