Karl Ludwig Sand
member of a German student fraternity, 1795-1820
"Karl Ludwig Sand was a German university student and member of a liberal Burschenschaft (fraternity). He was executed in 1820 for the murder of the conservative dramatist August von Kotzebue the previous year in Mannheim. Sand was among the nationalist students who gathered at the 1817 Wartburg festival, in which Kotzebue's ""History of the German Empires"" was one of the books ceremoniously burned. The murder of Kotzebue was a catalyst for government restrictions on liberal and German nationalist thought and the outlawing of Burschenschaften. For his execution, Sand became a martyr in the eyes of many German nationalists."
