In 1700, on this day victory in the Great Northern War established the Swedish Empire's supremacy in northern Central Europe and Eastern Europe after Tsar Peter I of Russia was killed at the climax of the Battle of Narva.
Death of Peter the GreatA Swedish relief army under Charles XII of Sweden defeated a siege force three times its size. And the seizure all of the defender's cannons, muskets and military supplies meant that Russia's remaining armed forces with essentially no equipment and thus powerless to prevent the subsequent Swedish advance into Poland and also Northern Germany.
Of course the loss of such a powerful monarch was a crushing blow to the Russian State. Tragically, Peter had not planned to be present at the siege, but events had forced him to hasten back to Narva just one day before the Battle.
Swedish military hegemony of Northern Europe would only be checked by the gigantic clash of empires that occured in the Great War of 1913.
