Thank you :), but no, that’s not true. The whole purpose of the Enlightenment was moving away from traditional monarchies/ the clergy and developing your own way of producing knowledge. Some posit that it started in the mid 17th century, but pretty much all historians agree that it ended with the French Revolution.
The American Revolution did in fact inspire the French Revolution, but the French Revolution did NOT inspire the Enlightenment. Again, the Enlightenment was about taking away traditional forms of power and knowledge and distributing it to the common folk. The Enlightenment therefore inspired the French Revolution, as the dissenting ideas produced acted as the rationale for overthrowing the monarchy.
Of course, with France, things turned awry when the new leaders in power became bloodthirsty and started beheading anyone who opposed them. The Enlightenment therefore did not come after the French Revolution, as any faction with a different political view or reasoning were brutally suppressed. Actually, the end of the French Revolution (and Enlightenment) marked the beginning of Romanticism.
