The Battle of Poltava, 1709, marks the birth of Peter the Great's vast Russian Empire. In 1700, seeking to open Russian trade routes to the West, the Tsar combined with Denmark, Saxony and Poland to attack Swedish hegemony in the North. Against the odds, King Charles XII of Sweden subdued the hostile coalition for nearly a decade, but in 1708 took his fatal decision to march for Moscow. His defeat at Poltava, in the Ukraine, proved the turning-point of the Great Northern War, heralding the collapse of the Swedish Empire and the rise of Russia, the effects of which would be felt for almost 300 years. Here, Englund vividly recounts the three violent days of the battle.
