Bastille Day
As early as 1789, the year of the storming of the Bastille, preliminary designs for a national festival were underway. These designs were intended to strengthen the country's national identity through the celebration of the events of 14 July 1789. One of the first designs was proposed by Clément Gonchon, a French textile worker, who presented his design for a festival celebrating the anniversary of the storming of the Bastille to the French city administration and the public on 9 December 1789. There were other proposals and unofficial celebrations of 14 July 1789, but the official festival sponsored by the National Assembly was called the Fête de la Fédération.
