During the French Revolution, artists, musicians, and other cultural producers criticized the French monarchy as well as the religious institutions of France. Artists who were skeptical of religion, or those who took a critical stance against the French monarchy, often hid their work from public eye. After the famous writer and philosopher Anacharsis Cloots was executed during the Reign of Terror for speaking out against the despotism of the French crown, writers like him were less likely to circulate their works. Those who did lived in constant fear for their lives. Tyranny, fear, violence and uncertainty diminished the productivity of radical thinkers.
