Lettres de Cachet were orders issued by the King of France, sealed with the royal seal (the cachet). These letters could command anything from imprisonment to exile or other arbitrary decrees, bypassing the usual judicial process. Although the monarchs claimed they were tools for maintaining public order and security, the letters often generated widespread resentment due to their application for personal and political reasons. Nobility, including prominent families and rival courtiers, sometimes exploited Lettres de Cachet to settle personal vendettas. This misuse added to the growing distrust and discontent among the populace. Many individuals were subjected to harsh penalties without any formal charges or trials; these arbitrary acts undermined the concept of justice. For example, well-known figures like the philosopher Voltaire faced imprisonment in the Bastille through such letters. His writings against the misuse of Lettres de Cachet helped in amplifying public outrage. The secretive and unfair nature of Lettres de Cachet was emblematic of the broader inefficacies and injustices within the Ancien Régime. Wealthy and influential individuals could secure these documents to remove competitors or adversaries (often facilitating corruption and favoritism). This led to the perception of a system that favored the elite and neglected the common people. The resentment simmered not only among the unjustly penalized but also within the wider society that witnessed these abuses. During the latter stages of Louis XVI's reign, the general atmosphere of corruption and privilege became increasingly intolerable. As Enlightenment ideas spread, highlighting equality and individual rights, the arbitrary power symbolized by Lettres de Cachet became even more unacceptable. The practice was one of the many grievances aired during the lead-up to the Estates-General in 1789, where sweeping reforms were demanded. Ultimately, Lettres de Cachet exemplified the autocratic and unaccountable nature of the monarchy, contributing significantly to the revolutionary fervor. Individual abuses compiled into a collective belief that the entire system was inherently flawed and unjust. This sentiment was instrumental in driving the revolutionaries to dismantle such symbols of royal prerogative and create a legal framework grounded in the principles of justice and equality.
