Only one year after the inception of the Rhein University the dramatist August von Kotzebue was murdered by Karl Ludwig Sand, a student at the University of Jena. The Carlsbad Decrees, introduced on 20 September 1819 led to a general crackdown on universities, the dissolution of the Burschenschaften and the introduction of censorship laws. One victim was the author and poet Ernst Moritz Arndt, who, freshly appointed university professor in Bonn, was banned from teaching. Only after the death of Frederick William III in 1840 was he reinstated in his professorship. Another consequence of the Carlsbad Decrees was the refusal by Frederick William III to confer the chain of office, the official seal and an official name to the new university. The Rhine University was thus nameless until 1840, when the new King of Prussia, Frederick William IV gave it the official name Rheinische Friedrich-Wilhelms-Universität. (This last sentence conflicts with pg. 176 of "Die Preussischen Universitäten", which states a cabinet order on 28 June 1828 gave the university the following name: Rheinische Friedrich-Wilhelms Universität.)
