"Cardinal Secretary of State, Eugenio Pacelli (later to become Pope Pius XII) signs the Concordat between Nazi Germany and the Vatican at a formal ceremony in Rome on 20 July 1933. Nazi Vice-Chancellor Franz von Papen sits at the left, Pacelli in the middle, and the Rudolf Buttmann sits at the right. The Concordat effectively legitimized Hitler and the Nazi government to the eyes of Catholicism, Christianity, and the world."
On 22 May 1939, Italy and Germany agree to a
military and political alliance, giving birth formally to the Axis
powers, which will ultimately include Japan.
Mussolini coined the nickname "Pact of Steel" (he had also come up
with the metaphor of an "axis" binding Rome and Berlin) after
reconsidering his first choice, "Pact of Blood," to describe this
historic agreement with Germany. The Duce saw this partnership as not
only a defensive alliance, protection from the Western democracies, with
whom he anticipated war, but also a source of backing for his Balkan
adventures. Both sides were fearful and distrustful of the other, and
only sketchily shared their prospective plans. The result was both Italy
and Germany, rather than acting in unison, would often "react" to the
precipitate military action of the other. In September 1940, the Pact of
Steel would become the Tripartite Pact, with Japan making up the third
constituent of the triad.
