toned down or taken back (Mitigation Laws 1880–1883 and Peace Laws 1886/87), but the Jesuits Law and the Pulpit Law were not repealed until 1917 and 1953, respectively. The changes concerning schools, civil registry, marriage and religious disaffiliation remain in place today. The Center Party gained strength and became an ally of Bismarck, especially when he attacked socialism. Weimar Republic and Nazi Germany (1918–1945) The national constitution of 1919 determined that the newly formed Weimar Republic had no state church, and guaranteed freedom of religion. Earlier, these freedoms were mentioned only in state constitutions. Protestants and Catholics were equal before the law, and freethought flourished. The German Freethinkers League attained about 500,000 members, many of whom were atheists, before the organisation was shut down by the Nazis in May 1933. When Adolf Hitler's Nazi Party seized power in January 1933, it sought to assert state supremacy over all sectors of life. The Reichskonkordat neutralized the Catholic Church as a political force. Through the pro-Nazi Deutsche Christenbewegung ("German Christians movement") and the forced merger of the German Evangelical Church Confederation into the Protestant Reich Church, Protestantism was brought under state control. Following a "gradual worsening of relations" in late 1936, the Nazis supported Kirchenaustrittsbewegung ("movement to leave the church"). Although there was no top-down official directive to revoke church membership, some Nazi Party members started doing so voluntarily and put other members under pressure to follow their example. Those who left the churches were designated as Gottgläubig: they believed in a higher power, often a creator-God with a special interest in the German nation, but did not belong to any church, nor were they atheists. Many were Germanic neopagans. This movement, especially promoted by Reichsführer-SS Heinrich Himmler, remained relatively small and by 1939, 3.5% of Germans identified as Gottgläubig; the overwhelming majority of 94.5% remained Protestant or Catholic, and only 1.5% did not profess any faith. Since 1933, Jews in Germany were increasingly marginalised, expelled and persecuted for a combination of religious, racial and economic reasons. From 1941 to the fall of Nazi Germany in 1945, they were actively massacred during the Holocaust. Cold War and contemporary period (1945–present) In the aftermath of World War II, two states emerged in Germany in 1949: West Germany under the aegis of the Western Allies, and East Germany as part of the Soviet bloc. West Germany, officially known as the Federal Republic of Germany,
