Pope Martin IV
The next pope, Pope Nicholas III, although from the powerful Roman Orsini family, also died in Viterbo in 1280. During the ensuing election, the magistrates of Viterbo threw two Orsini cardinals into prison. By the time his successor, Pope Martin IV, was elected, Viterbo had been placed under interdict, and because the French pope was resented in Rome, he was crowned in Orvieto. The influence of Viterbo on the papacy declined after Martin IV's death in Perugia in 1285.
