1594～1632年
Gustav II Adolf
King of Sweden (1611-32) who made Sweden a major European power. The son of Charles IX, Gustav inherited his father's dynastic quarrels with Sigismund III Vasa and until 1629 faced a legitimist invasion from Poland. He ended the war with Denmark in 1613, but Sweden was forced to pay a crushing war indemnity. He ended the war with Russia (1617) and annexed Ingria and Kexholm. Internal tensions were largely resolved by his trusted chancellor, Axel Gustafsson Oxenstierna. Gustav's sweeping domestic reforms included establishing an efficient central administration and improving education. Resuming the war with Sigismund in 1621, Gustav obtained much of Polish Livonia (Latvia and Estonia). He saw his Polish campaigns as part of the struggle of Protestantism against the Counter-Reformation. He entered the Thirty Years' War in 1630 as a defensive maneuver, to secure the Swedish state and church from danger. An outstanding military tactician, he led an army of unusual quality, and his position was strengthened by alliances with France, Brandenburg, and Saxony. Success in the Battle of Breitenfeld let him sweep through central Germany and claim large territorial cessions, particularly Pomerania (1631). At Lützen in 1632, the Swedes defeated Albrecht W. E. von Wallenstein's army, but Gustav was killed in battle.
