Antipope Felix II was installed as Pope in 355 after the Emperor Constantius II banished the reigning Pope, Liberius, for refusing to subscribe the sentence of condemnation against Saint Athanasius. In May 357 the Roman laity, which had remained faithful to Liberius, demanded that Constantius, who was on a visit to Rome, should recall Liberius. The Emperor planned to have Felix and Liberius rule jointly, but when Liberius returned Felix was forced to retire to Porto, near Rome, where, after making an unsuccessful attempt to establish himself again in Rome, he died on 22 November 365.
