Puncturing their professed self-image as legitimate civil society groups, over the years, various Ülkücü groups have been implicated in violent acts in Germany that expose the dark, criminal underbelly of many of its members. For example, Turkish ultranationalists cropped up as a subculture of renegade biker gangs, most famously known as Osmanen Germania BC (Germania Ottomans). With around 300 members, the group was banned in Germany in 2018, amid raids in the states of Rhineland-Palatinate, Baden Württemberg, Bavaria, and Hesse. Members were prosecuted for carrying out violent crimes, including attempted murder, extortion, drug trafficking, deprivation of liberty, and forced prostitution.
