I was thinking about assassinations and realized that the Russian royal family had of course had more assassinations than any other family.
But excluding the 1918 murders, the Romanovs run a tight race with the Hapsburgs.
Romanov:
Peter III, Paul, Alexander II, Grand Duke Serge
Hapsburg:
Archduke Franz Ferdinand and the Duchess of Hohenberg, Emperor Maximilian, Empress Elisabeth
Am I leaving any out?
Can anyone think of any other assassinated royals? All that comes to my mind is:
King George I of Greece
