What do you think we're the most important long term effects of the French Revolution?

The long term effect lasting to 21st century is establishment of universal civic rights and sense of all subjects in the state sharing the same standing in front of law, concept of citizenship, and a civic participation. Secondary effect was a dissolution of Church as power over the life of people, education, social services, and family. Faith became the internal matter of the individual, a personal matter of the citizens. Western world with exception of USA is deeply secular, and this can be directly attributed to the effect of the French Revolution. USA in its early decades was unable to give women universal votes, freed slaves, or decriminalized same-sex relationships, something what French were addressing 220 years ago
