The president of the United States in Congress Assembled, known unofficially as the president of the Continental Congress and later as president of the Congress of the Confederation, was the presiding officer of the Continental Congress, the convention of delegates that assembled in Philadelphia as the first transitional national government of the United States during the American Revolution. The president was a member of Congress elected by the other delegates to serve as a neutral discussion moderator during meetings of Congress. Designed to be a largely ceremonial position without much influence, the office was unrelated to the later office of President of the United States.

President is a common title for the head of state in most republics. The president of a state is, generally speaking, the head of the government and the fundamental leader of the country or the ceremonial head of state.
