In March 1933, the president of an interfaith group asked for Bertram's aid in protesting the boycott of Jewish business organised by the Nazis but was refused as he regarded it as purely an economic matter and because, in his opinion, the Jewish press had kept silent about the persecution of Catholics. On the eve of the Second World War, Nazi Germany and, to a much lesser extent, Poland annexed parts of
Czechoslovakia,
Sudetenland and
Trans-Olza, whose northern part was a component of Bertram's diocese. After the Polish takeover of Trans-Olza, which was never internationally recognised, the Polish government requested the Holy See to depose Bertram from jurisdiction in the newly-Polish annexed area. The Holy See complied, and
Pope Pius XI then subjected the Catholic parishes in Trans-Olza to an
apostolic administration under
Stanisław Adamski, Bishop of Katowice, who wielded that administration until 31 December 1939.
World War II He ordered Church celebrations upon Nazi Germany's victory over Poland and France, with an order to ring bells all across the Reich upon the news of the German capture of Warsaw in 1939. With his knowledge, the diocese of Breslau issued a statement calling the war with Poland a "holy war" fought to enforce God's orders on how to live and regain "German lost land". Throughout most of World War II Cardinal Bertram remained in Breslau. Bertram opposed what he called the
immorality and "
neopaganism" of the
Nazi Party. On 23 December 1939
Cesare Orsenigo, Nuncio to Germany, appointed – with effect of 1 January 1940 – Bertram – and Olomouc' Archbishop
Leopold Prečan – as apostolic administrators for exactly those Catholic parishes of Trans-Olza, where Pius XI had deposed them in 1938. In 1940, Cardinal Bertram condemned the propaganda and planning for Operation
Lebensborn and Nazi vitalism and insemination plans as
"immoral", saying that the Lebensborn programme was institutionalized
"adultery". A few months after his death,
Time magazine wrote about Cardinal Bertram:Died. Adolf Cardinal Bertram, 86, outspoken anti-Nazi Archbishop of Breslau and dean of the German Catholic hierarchy, whose tireless resistance to Hitler's "neopaganism" was climaxed last March in his defiance of orders to evacuate Breslau before the advancing Russians; presumably in Breslau. His death left the
College of Cardinals with 40 members - the fewest in 144 years. In early 1941 Bertram as metropolitan bishop of the
Eastern German Ecclesiastical Province and speaker of the
Fulda Conference of Bishops, rejected
Carl Maria Splett's request to admit the
Danzig diocese as member in his ecclesiastical province and at the conference. ==Last years and death==
