When the Nazi Party emerged from obscurity to become a major political force after 1929, the conservative faction rapidly gained more influence, as wealthy donors took an interest in the Nazis as a potential bulwark against communism. The Nazi Party had previously been financed almost entirely from membership dues, but after 1929 its leadership began actively seeking donations from German industrialists, and Hitler began holding dozens of fundraising meetings with business leaders. In the midst of the Great Depression, facing the possibility of economic ruin on the one hand and a Communist or Social Democratic government on the other hand, German business increasingly turned to Nazism as offering a way out of the situation, by promising a state-driven economy that would support, rather than attack, existing business interests. By January 1933, the Nazi Party had secured the support of important sectors of German industry, mainly among the steel and coal producers, the insurance business and the chemical industry.
The courtyard between blocks 10 and 11, known as the "death wall" served as an execution area for Poles not in Auschwitz who had been sentenced to death by a criminal court—presided over by German judges—including for petty crimes such as stealing food. Several rooms in block 11 were deemed the Polizei-Ersatz-Gefängnis Myslowitz in Auschwitz ("Alternative jail of the police station at Mysłowice"). There were also Sonderbehandlung cases ("special treatment") for Poles and others regarded as dangerous to the Third Reich. Members of the camp resistance were shot there, as were 200 of the Sonderkommandos who took part in the Sonderkommando revolt in October 1944. Thousands of Poles were executed at the death wall; Höss wrote that "execution orders arrived in an unbroken stream".
Nazi Germany maintained concentration camps (German: Konzentrationslager, KZ or KL) throughout the territories it controlled before and during the Second World War. The first Nazi camps were erected in Germany in March 1933 immediately after Hitler became Chancellor and his Nazi Party was given control of the police by Reich Interior Minister Wilhelm Frick and Prussian Acting Interior Minister Hermann Göring. Used to hold and torture political opponents and union organizers, the camps initially held around 45,000 prisoners. In 1933–1939, before the onset of war, most prisoners consisted of German Communists, Socialists, Social Democrats, Roma, Jehovah's Witnesses, homosexuals, and persons accused of 'asocial' or socially 'deviant' behavior by the Germans.
