Pope Pius IX and Judaism

The relations between Pope Pius IX and Judaism were off to a good start at the beginning of his papacy, but relations later soured after anti-clerical revolutions removed most of the pontiff's temporal power, and he stiffened into intolerance. While Pius rejected charges of antisemitism, the rift created by the Mortara Affair, undermined his moral authority in the eyes of some during the rest of his pontificate.
