Statue of Saint Wenceslas

Wenceslaus I (c. 907 – September 28, 935), or Wenceslas I, was the duke (kníže) of Bohemia from 921 until his assassination in 935, purportedly in a plot by his own brother, Boleslav the Cruel.

His martyrdom, and the popularity of several biographies, quickly gave rise to a cult-like following and reputation of superhuman goodness, resulting in his being elevated to Sainthood, posthumously declared king, and seen as the patron saint of the Czech state. He is even the subject of a Christmas carol written in 1853 that remains popular to this day, Good King Wenceslas.
