Which son of Sophia of Hanover ruled part of the Holy Roman Empire?
Sophia of Hanover Sophia of the Palatinate (commonly referred to as Sophia of Hanover; 14 October 1630 – 8 June 1714) was the Electress of Hanover from 1692 to 1698. As a granddaughter of James VI and I, she became heir presumptive to the crowns of the Kingdom of England and the Kingdom of Ireland under the Act of Settlement 1701. After the Acts of Union 1707, she became heir presumptive to the unified throne of the Kingdom of Great Britain. She died less than two months before she would have become queen, and her claim to the throne passed on to her eldest son, George Louis, Elector of Hanover, who ascended as George I on 1 August 1714 (Old Style).
Electorate of Saxony The Electorate of Saxony (German: "" , also "Kursachsen "), sometimes referred to as Upper Saxony, was a State of the Holy Roman Empire established when Emperor Charles IV raised the Ascanian duchy of Saxe-Wittenberg to the status of an Electorate by the Golden Bull of 1356. Upon the extinction of the House of Ascania, it was enfeoffed to the Margraves of Meissen from the Wettin dynasty in 1423, who moved the residence up the Elbe river to Dresden. After the Empire's dissolution in 1806, the Wettin electors raised Saxony to a kingdom.
