Good King Wenceslas -- look out!
Petra Hanáková tells us:
This situation culminated in 1419 with the First Defenestration of Prague, in which Hussites threw 7 members of the Czech Town Council out of Prague's New Town Hall window--and to their deaths on the points of Hussite-wielded pikes below. To make the situation more interesting, King Wenceslas IV had an apoplectic fit and died of a heart attack upon learning of the defenestration.
