The French presidential inauguration is an event marking the beginning of a new term for the president of France.
The Constitution of France does not mention any requirements for the conduct of proceedings. However, over the years, various traditions have emerged, such that the inauguration is not merely a simple transfer of power but an entire day of parades, speeches, military and civil tributes, and general celebrations. Unlike many other countries, there is no oath of office.
The 'inauguration day' is set about ten days after the second round of the presidential election in France, no later than the last day the mandate of the outgoing president.
The "inauguration" includes not only the transfer of power between the president-elect and the outgoing president, but also of a variety of ceremonial devices, both civil and military. The day is still considered an "inauguration" ("investiture" in French) even if the incumbent President is re-elected. It must be held no later than the last day of the official mandate of the outgoing President or, in case of a vacancy as a result of resignation or death, as soon as possible the results of the presidential election have been made official by the Constitutional Council. Under the Third and Fourth republics, the president-elect was inaugurated immediately on the day of their election by both houses of the Parliament, the ceremony taking place in the Marengo room (adjacent to the office of the president of Congress) of the Palace of Versailles. The inauguration of president of the French Republic is now held in the ballroom of the Élysée Palace, the official residence of the presidency.
