Around 30 "Studentenverbindungen", the German type of fraternities, are associated with the university. While famous for their parties, public academic lectures and the yearly "Stocherkahn-Rennen" punting-boat race on the Neckar river, some of them are the subject of ongoing controversy surrounding alleged rightwing policial views, leading to strong criticism from leftist groups. The university itself takes a neutral stance on this issue. However, all of Tübingen's fraternities distance themselves from the fraternities of the Deutsche Burschenschaft, which have been widely criticized as adhering to far-right principles.
