 During his papacy, censorship reached new heights.Among his first acts as Pope was to cut off Michelangelo's pension, and he ordered the nudes of "The Last Judgment" in the Sistine Chapel be painted more modestly (a request that Michelangelo ignored) (the beginning of the Vatican's Fig leaf campaign).Paul IV also introduced the Index Librorum Prohibitorum or "Index of Prohibited Books" to Venice, then an independent and prosperous trading state, in order to crack down on the growing threat of Protestantism.
