Corps (or Korps; "das ~" (n), German pronunciation: [ˈkoːɐ] (sg.), [ˈkoːɐs] (pl.)) are the oldest still-existing kind of Studentenverbindung, Germany's traditional university corporations; their roots date back to the 15th century. The oldest corps still existing today was founded in 1789. Its members are referred to as corps students (Corpsstudenten). The corps belong to the tradition of student fraternities which wear couleur and practice academic fencing.
Most corps are organized in two federations, the Kösener Senioren-Convents-Verband (KSCV) and the Weinheimer Senioren-Convent (WSC). Together, they comprise 162 Corps throughout Germany, Austria, Belgium, Estonia, Latvia, Hungary, Switzerland and Lithuania.
The German Student Corps were traditionally recruited from the nobility, royalty, and social elite, and are traditionally viewed as more aristocratic and elitist than other German student fraternities such as the Catholic Cartellverband and the Burschenschaften. They consider tolerance and individuality to be key tenets and are rooted in German idealism. By and large, they are generally conservative in political outlook, but less right-wing and less nationalist than the Burschenschaften. The corps are open to students of all nationalities and religions, unlike many other student fraternities. Although distinct, the corps are in some aspects similar to and serve many of the same purposes as college fraternities found in the United States.
