From the earliest days of the Nazi takeover in Germany, the Vatican was taking diplomatic action to attempt to defend the Jews of Germany. In the spring of 1933, Pope Pius XI urged Mussolini to ask Hitler to restrain the anti-Semitic actions taking place in Germany. Mussolini urged Pius to excommunicate Hitler, as he thought it would render him less powerful in Catholic Austria and reduce the danger to Italy and wider Europe. The Vatican refused to comply and thereafter Mussolini began to work with Hitler, adopting his anti-Semitic and race theories. In 1936, with the Church in Germany facing clear persecution, Italy and Germany agreed to the Berlin-Rome Axis.
