The 935 assassination of a pious duke made him the patron saint of Czechs
A tragic act of fratricide in 935 transformed Duke Wenceslas I from a local ruler into the eternal 'Good King' and the enduring spiritual symbol of the Czech nation.
In 935, Duke Wenceslas I was assassinated by his brother, Boleslav the Cruel, at the entrance of a church in Stara Boleslav. Although he was a duke, his reputation for extreme piety and compassion toward the poor earned him the posthumous title of King and inspired the famous Christmas carol 'Good King Wenceslas.'
