Saint Wenceslaus I was a 10th-century ruler who served as the Duke of Bohemia from 921 until his death in 935. Born into the Přemyslid dynasty, he was raised in the Christian faith and sought to strengthen his state through religious devotion. His reign was marked by efforts to consolidate power and the introduction of the Latin rite within his territory. He was eventually assassinated by a group of nobles, including his own brother, Boleslav, during a feast in Stará Boleslav.
