Which fortress in Paris was stormed on July 14, 1789, marking the beginning of the French Revolution?

The storming of the Bastille on July 14, 1789, is a pivotal event that marks the beginning of the French Revolution. The Bastille was a fortress and prison in Paris that symbolized the tyranny of the Bourbon monarchy. Its capture by revolutionaries represented not just a physical attack on a government building, but also a significant challenge to royal authority and the status quo in France. This event is often celebrated as a symbol of liberty and the fight against oppression, leading to the eventual rise of democratic ideals in France and influencing revolutions around the world.

The other options, such as the Louvre and the Tuileries, while historically significant, were not the sites associated with the initial outbreak of revolutionary fervor. The Louvre served as a royal palace and later became a museum, and the Tuileries was another royal residence. The Citadel, which could reference various military fortifications, does not have the same symbolic significance in the context of the French Revolution. Thus, the storming of the Bastille stands out as the defining moment of revolutionary action, making it the correct answer.
