The event with historical implications that contributed to the storming of the Bastille is related to the Tennis Court Oath (D).
The Tennis Court Oath, which took place in June 1789, was a pivotal moment in the early stages of the French Revolution. It involved members of the Third Estate, who pledged not to disband until they had drafted a new constitution for France, reflecting their grievances against the monarchy. This act of defiance fueled tensions between the King and the revolutionaries, leading to a growing sense of urgency and unrest among the populace.
While other events listed (such as the Reign of Terror or the actions of Louis XVI) were significant in the broader context of the French Revolution, they occurred after the storming of the Bastille in July 1789. The storming of the Bastille itself was driven more directly by the immediate political climate, economic issues, and fears of repressive actions by the King. Thus, (D) is the most relevant choice regarding the storming of the Bastille.
