Youth organizations other than those led by the Nazi party were dissolved and officially forbidden in 1936. Both Hans Scholl and Willi Graf were arrested in 1937–38 because of their membership in forbidden Youth Movement organizations. Hans Scholl had joined the 1. 11. in 1934, when he and other Hitler Youth members in Ulm considered membership in this group and the Hitler Youth to be compatible. Hans Scholl was also accused of transgressing the German anti-homosexuality law, because of a same-sex teen relationship dating back to 1934–1935, when Hans was only 16 years old. The argument was built partially on the work of Eckard Holler, a sociologist specializing in the German Youth Movement, as well as on the Gestapo interrogation transcripts from the 1937–38 arrest, and with reference to historian George Mosse's discussion of the homoerotic aspects of the German Youth Movement. As Mosse indicated, idealized romantic attachments among male youths were not uncommon in Germany, especially among members of the associations. It was argued that the experience of being persecuted may have led both Hans and Sophie to identify with the victims of the Nazi state, providing another explanation for why Hans and Sophie Scholl made their way from ardent "Hitler Youth" leaders to passionate opponents of the Nazi regime.
