There were soon attempts by King Louis XVI and the Second Estate to prevent the delegates from meeting, as well as misunderstandings on both sides about each other's intentions. Locked out of its chamber, the new assembly, led by its president Jean-Sylvain Bailly, was forced to relocate to a nearby tennis court, on 20 June;[4] there, it swore the Tennis Court Oath, (Le serment de Jeu de Paume) promising "not to separate, and to reassemble wherever circumstances require, until the constitution of the kingdom is established and consolidated upon solid foundations."[5] Failing to disperse the delegates, Louis started to recognize their validity on 27 June.[6]
