Agnes Bernauer
Agnes Bernauer (c. 1410 – 12 October 1435) was the mistress and perhaps also the first wife of Albert, later Albert III, Duke of Bavaria.
Because his father, Ernest, ruling Duke of Bavaria at the time, considered this liaison with a commoner unbefitting his son's social standing, he clashed with his son over the matter and finally arranged to have Agnes condemned for witchcraft and drowned in the Danube in 1435.
Her life and death have been depicted in numerous literary works, the most well known being Friedrich Hebbel's tragedy of the same name and the folk
musical "Die Bernauerin" by the composer Carl Orff.
