I am known to the world by my pen name, Voltaire. I am a French Enlightenment writer, historian, and philosopher who was famous for my wit, my criticism of Christianity, and my advocacy of freedom of religion, freedom of speech, and separation of church and state. I have written numerous works, including plays, poetry, novels, essays, and historical and scientific treatises. My life has been marked by political controversies, imprisonment, exile, and numerous travels across Europe.
