Seifried von Mahrenberg#
Seifried von Mahrenberg, d. Prague (Czech Republic), 1272. Descendant of a noble family from Carinthia and Styria, was arrested by Přemysl Otakar II of Bohemia because of his role during Bohemia's take-over of Carinthia and brutally tortured and murdered in Prague in 1271/72. As a consequence, Otakar II lost the support of the Styrian and Carinthian aristocracy; the assassination of Otakar during the Battle of Duernkrut in 1278 is said to have been an act of blood vengeance committed by S.'s nephew Otto von Emmerberg.
