When Heinrich Himmler banned the Baha’i Faith in Germany in 1937, he blamed it on the religion’s “international and pacifist tendencies.”  The Nazi government increasingly targeted the Baha’is after Himmler’s edict, first by tearing down the public memorial to Abdu’l-Baha in Bad Mergntheim and then, in 1939, making mass arrests of the former members of the German Baha’i National Spiritual Assembly.  Baha’is went to jail, some for very long periods, without charges.  In 1942, more mass arrests occurred.  Many of the Baha’is from Germany and the surrounding countries disappeared in the Nazi concentration camp system, and the details of their fates, like millions of others, will probably never be known.
