This student was Karl Ludwig Sand, a Bavarian who studied Theology in Jena. He was the founder of a Burschenschaft in Erlangen (Bavaria). He saw von Kotzebue as a traitor to Germany and a Russian spy and thus decided to kill him. He travelled to Mannheim and stabbed von Kotzebue in his own house, shouting "Here, you traitor to the fatherland!". Then he tried to kill himself, but the wounds were superficial. Two months later he was sentenced to death and beheaded outside one Mannheim's city walls. He was buried in the same cemetery as von Kotzebue and their graves are about 200 metres apart. In reaction to the killing of von Kotzbue, the German Confederation passed the so-called Karlsbad Laws, which imposed censorship on the press and contained measures against radical students, professors and Burschenschaften. Only in 1848 were these laws revoked. They didn't crush nationalism and the wish for German unification though and in 1871 unification was at last realized (but maybe not in the way Sand and his friends had wished...).
