A Burschenschaft (German: [ˈbʊʁʃn̩ʃaft]; sometimes abbreviated B! in the German Burschenschaft jargon; plural: B!B!) is one of the traditional Studentenverbindungen (student associations) of Germany, Austria, and Chile (the latter due to German cultural influence). Burschenschaften were founded in the 19th century as associations of university students inspired by liberal and nationalistic ideas. They were significantly involved in the March Revolution and the unification of Germany. After the formation of the German Empire in 1871, they faced a crisis, as their main political objective had been realized. So-called Reformburschenschaften were established, but these were dissolved by the Nazi regime in 1935/6. In West Germany, the Burschenschaften were re-established in the 1950s, but they faced a renewed crisis in the 1960s and 1970s, as the mainstream political outlook of the German student movement of that period started leaning more towards the left. Roughly 160 Burschenschaften exist today in Germany, Austria and Chile.
