Czech duke (c. 921 - 935) and saint (Patron of Czech Lands and Přemyslid dynasty). Son of prince Vratislav I. and (probably) Drahomira of Stodor from the family of the Havolans of the Elbe region. *c. 900 - +28 September 935

"On the 31st of July, the nobles and elders of the Bohemian land took for themselves as prince or king the son of the same king Wenceslas, named Přemysl, and swore allegiance to him in the cloister of the Prague church, though his father knew nothing of it." This reference by the chronicler to the year 1249 (correctly 1248) announces the beginning of the rebellion of Přemysl (Ottokar in German lands), Margrave of Moravia, against his father Wenceslaus I. Although (but also because) the young Přemysl was the only possible successor to his father and could only be stripped of the throne by his death to the throne only his death could remove him, it is necessary to shed more light on the causes and the situation in the Bohemian kingdom that led the Bohemian nobility to elect a new king.
