Det tyske kommunistpartis illegale apparat 1919-1937

The article describes the illegal apparatus of the German Communist Party, KPD, 1919-1937 including how some of its members especially from Hamburg came to Denmark after 1933 bringing internal conflicts from there into the small group of german communists in exile in Copenhagen. The illegal apparatus of KPD used different names, but here AM-apparatus is used also for earlier years; am standing for abteilung militärpolitik but also used as anti militarist if some were brought for a court. The apparatus worked closely with advisors from soviet union, its BB section dealing with industrial espionage worked for instance closely with the soviet military intelligence (named gru in 1942), that took over the BB section from KPD in 1934. until 1935 the people from the illegal apparatus were able to better work on the new, harsh situation with Hitler as dictator, but in 1933 one task was still to prepare rebellions, as stalin in moscow still saw the situation in germany as ripe for a communist revolution. From 1935 also the illegal apparatus was hit very hard by detentions of its members. at the same time the new KPD leadership in exile, especially Walter Ulbricht, was against the illegal apparatus, and it was dismantled in two phases 1936-37.
