Audita tremendi was a papal bull written by Pope Gregory VIII in October of 1187, calling for the Third Crusade. It was issued in response to the defeat of the Kingdom of Jerusalem at the Battle of Hattin on July 4 of that year; although unknown in Europe at the time, the city of Jerusalem itself had fallen to Saladin earlier in October (see Siege of Jerusalem. Audita tremendi follows the same format as Quantum praedecessores, the bull calling for the Second Crusade in 1147. It focuses specifically on the loss of Jerusalem and points to the sins of the Latin States as the reason for this great loss. As a result the people of Latin Christendom must repent for their sins. The bull offered a plenary indulgence to all who went on it; thus through this logic the bull draws the conclusion that due to the sins of the west Jerusalem fell and now the people of the west must repent by going on a crusade to recapture the kingdom.
