The event that had historical implications contributing to the storming of the Bastille was the Tennis Court Oath because they were arrested for their demands.
The Tennis Court Oath, taken by members of the Third Estate on June 20, 1789, was a pivotal moment in the early stages of the French Revolution. It expressed the demand for a new constitution and set the stage for the conflict between the monarchy and the people, leading to increased tensions that culminated in the storming of the Bastille on July 14, 1789.
