1120 POPE CALIXTUS II (1119-24)
Issued the protective bull, (Constitutio pro Judaeis), condemning the persecution of Jews. The term "bull" referred to an official document issued by various Popes and is taken from the Latin bullum, "seal". This specific bull was not "pro Jewish" per se, but rather reflected the Church's official position, as stated by Pope Gregory I (598), which objected to forced conversions or the wanton destruction of synagogues. Often newly elected Popes would issue a similar pro Judaeis bull after receiving a gift from the Jewish community.

Finally surrendered to the Crusaders. The Jewish population was not harmed.

He composed commentaries on talmudic texts which had been mostly ignored up to his day, as well as the Mishna, Sefrei and Mekhilta.
