Tennis Court Oath
The Tennis Court Oath (French: Serment du Jeu de Paume, pronounced [sɛʁmɑ̃ dy ʒø də pom]) was taken on 20 June 1789 by the members of the French Third Estate in the hall of an indoor tennis court in the grounds of Versailles. Their vow "not to separate and to reassemble wherever necessary until the constitution of the kingdom is established" became a pivotal event in the French Revolution.
