Prince Václav was killed by his brother, Boleslav I. Later he was worshipped as a saint and from the eleventh century he became patron of the Czech lands and the symbol of Czech statehood. King Václav III was also killed, and he was the last male descendant of the Přemyslids dynasty. Václav is still the most common Slavonic name in the Czech Republic. (M 34628) _ _.
