What did the third estate do after the king rejected their list of grievances?

After the king rejected their list of grievances in 1789, the Third Estate declared itself the National Assembly, asserting that they represented the people of France. They took the Tennis Court Oath, vowing not to disband until they had drafted a new constitution for the country. This act marked a pivotal moment in the French Revolution, signifying a break from the traditional authority of the monarchy and the beginning of a struggle for greater representation and rights for the common people.
