Frederick and King Louis VII of France. For the next three years nothing is known of Callixtus' activities. Frederick, when it became politically expedient, after the defeat of Legnano, switched his backing to Alexander. In November 1176, he signed the Pact of Anagni, which did, however, protect Callixtus by granting him an abbacy and restoring the cardinals he had created to their former offices. These terms were confirmed in the final Peace of Venice in July 1177. Callixtus did not immediately recognize the Peace of Venice, but in 1178 Archbishop Christian of Mainz, the imperial chancellor, marched an army into Italy to retake the Papal State and Rome for Alexander. This rendered Callixtus' position at Viterbo untenable, and he fled to Monte Albano. On 29 August 1178, Callixtus submitted to Alexander III at Tusculum and abjured the schism. The pope entertained him with a feast. Some of his obstinate partisans sought to substitute a new antipope, and chose one Lando di Sezze under the name of Innocent III. Alexander appointed Callixtus rector of Benevento. He still held that position in 1180, but by 1184 he was dead.
