Bastille Day is the French National Day which is celebrated on 14 July of each year. In France, it is formally called La Fête Nationale (The National Celebration) and commonly le quatorze juillet (the fourteenth of July).
It commemorates the 1790 Fête de la Fédération, held on the first anniversary of the storming of the Bastille on 14 July 1789; the anniversary of the storming of the Bastille fortress-prison was seen as a symbol of the uprising of the modern nation, and of the reconciliation of all the French inside the constitutional monarchy which preceded the First Republic, during the French Revolution.
Festivities and official ceremonies are held all over France. The oldest and largest regular military parade in Europe is held on the morning of 14 July, on the Champs-Élysées avenue in Paris in front of the President of the Republic, French officials and foreign guests
On 17 May 1789, Louis XVI convened the Estates-General to hear their grievances. The deputies of the Third Estate representing the common people (the two others were the Catholic Church and nobility) decided to break away and form a National Assembly. On 20 June the deputies of the Third Estate took the Tennis Court Oath, swearing not to separate until a constitution had been established. They were gradually joined by delegates of the other estates; Louis XVI started to recognize their validity on 27 June. The assembly re-named itself the National Constituent Assembly on 9 July, and began to function as a legislature and to draft a constitution.
