French Revolution: Frederick William II of Prussia and Leopold II, Holy Roman Emperor, issue the Declaration of Pillnitz, declaring the joint support of the Holy Roman Empire and Prussia for the French monarchy, agitating the French revolutionaries and contributing to the outbreak of the War of the First Coalition.

The French Revolution was a period of political and societal change in France that began with the Estates General of 1789 and ended with the Coup of 18 Brumaire on 9 November 1799. Many of the revolution's ideas are considered fundamental principles of liberal democracy, and its values remain central to modern French political discourse.

It was caused by a combination of social, political, and economic factors which the existing regime proved unable to manage.
