Coat of arms of the House of Vasa.

The House of Vasa was the Royal House of Sweden (1523-1654) and of Poland (1587-1668). Gustavus II Adolphus Vasa inherited a feud with the Polish ruling line of Sigismund III Vasa, who was deposed as king of Sweden in 1599. Sigismund started a series of protracted wars to regain the throne. Gustavus himself began the next round with an invasion of Livonia, kicking off the Polish-Swedish War (1625–1629). Protestants suffering through the Thirty Years' War asked Gustavus to intervene. Christina, Gustavus's sole legitimate issue, abdicated the Swedish throne in 1654, six years after the end of the Thirty Years' War.

House of Vasa in 1632Edit

Due to the presence of Grantville, the Swedish branch of the House of Vasa flourished, with Gustavus Adolphus avoiding his historical death and becoming the Emperor of the United States of Europe.
