The last European monarch to die in battle is generally agreed to have been Charles XII of Sweden, better known to metalheads as Carolus Rex, who was fatally shot in 1718 during the Siege of Fredriksten (though there are theories that he was actually assassinated).
Your challenge is to have a European monarch be killed in action after 1718.
