These challenges led to suppression from church and state authorities. The "Encyclopédie" and its contributors endured many attacks and attempts at censorship by the clergy or other censors, which threatened the publication of the project as well as the authors themselves. The King's Council suppressed the "Encyclopédie" in 1759. The Catholic Church, under Pope Clement XIII, placed it on its list of banned books. Prominent intellectuals criticized it, most famously Lefranc de Pompignan at the French Academy. A playwright, Charles Palissot de Montenoy, wrote a play called "Les Philosophes" to criticize the "Encyclopédie". When Abbé André Morellet, one of the contributors to the "Encyclopédie", wrote a mock preface for it, he was sent to the Bastille due to allegations of libel.
