Heinrich Himmler, one of the most infamous mass murderers of all time, was originially from a conservative and Catholic family in Bavaria. Later he would break away from the church. Himmler and his SS are responsible for the murders of 6 million Jews. The Allied Forces knew more about this during the war than they care to admit, since the British had broken the SS-codes. Himmler was heavily involved in the state-of-affairs of the Netherlands and Belgium. However, he clashed with NSB-collaborator Mussert and several Flemish collaborators. They, unlike Himmler, did not wish to see the Netherlands and Belgium completely immersed in the Third Reich. An often overlooked aspect of the 'Reichsführer-SS' is his fascination with Eastern religions and Islam. Astrology and the occult spoke to him as well. What fascinated Himmler about the Islam was the contempt for death that Islamic warriors showed when they marched to die as martyrs. Himmler's best friend was Haj Amin Al-Husseini, the Grand Mufti of Jeruzalem.
