Discuss how Bastille Prison was a symbol of autocracy.

The Bastille was not a significant military installation by the time of the French Revolution, but its capture by the Parisian crowd and its subsequent destruction was deeply symbolic.
This is because, for most of its history, the giant, forbidding fortress had been used by French kings to house political dissidents. The King was empowered to simply imprison people who had been vocal critics of the monarchy, whose behavior had been an embarrassment to the royal court. Under French tradition, the king could issue warrants known as lettres de cachet under which people could be imprisoned without any other cause. These unfortunate people were often sent to the Bastille, which had become infamous for grim conditions and torture.
For this reason, though only a handful of people were still imprisoned there by July of 1789, the Parisian crowd stormed the Bastille as part of the first wave of the French Revolution. Its fall symbolized the collapse of the arbitrary tyranny of the Bourbon monarchs.
