Jean Sylvain Bailly was a French astronomer, mathematician, freemason, and political leader of the early part of the French Revolution. He presided over the Tennis Court Oath, served as the mayor of Paris from 1789 to 1791, and was ultimately guillotined during the Reign of Terror.

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 in November 1799 and the formation of the French Consulate. Many of its ideas are considered fundamental principles of liberal democracy, while its values and institutions remain central to modern French political discourse.
