When the Estates-General convened in May 1789, members of the Third Estate, representing the common people, took significant actions to assert their power. Frustrated by the voting process, which favored the privileged classes, they declared themselves the National Assembly on June 17, 1789, asserting their role as the legitimate representative body of the French people. They also pledged the Tennis Court Oath on June 20, vowing not to disband until a new constitution was established, marking a pivotal step toward the French Revolution.
