The inauguration of a President represents an important symbol of democracy in the United States, as the President will publicly swear that:
“ I will faithfully execute the Office of President of the United States, and will to the best of my Ability, preserve, protect and defend the Constitution of the United States."
When written, this oath was revolutionary because the President swears their allegiance not to a country or an individual, but instead to the ideas of the United States Constitution—democracy, federalism, and the separation of powers. The President is stating he is bound to the rules outlined in the Constitution and it is his job to protect and enforce this document.
