Third Estate suggests to meet and that each delegate have a vote. The King orders them to follow medieval rules. Emmanuel-Joseph Sieyès suggests the 3rd Estate delegates name themselves the National Assembly and pass laws/reforms in their name. On June 17, 1789 they voted to establish the Assembly, proclaiming the end of absolute monarchy.
Three days after the National Assembly was formed, the 3rd Estate delegates were locked out of their meeting room. They broke down a door to an indoor tennis court, vowing to stay there and make a new constitution. The pledge made was called the Tennis Court Oath. Some nobles and members of clergy who favored change met with the delegates. In response to this, Louis stationed his army of Swiss guards around Versailles.
Many people believed that Louis' intentions were to use military force to dispel the National Assembly. Others believed the troops were meant to come to Paris and massacre the citizens. People began gathering weapons and on July 14, 1789, a mob looking for firearms stormed the Bastille, a Paris prison. The mob overwhelmed the guards who were eventually hacked to death. They seized control of the building and paraded around the streets with the dead men's heads on pikes.
