Wer heiratete Ernst August (Hannover)?

Ernst August von Braunschweig-Calenberg (* 20. November 1629 auf Schloss Herzberg in Herzberg am Harz; † 23. Januar 1698 in Schloss Herrenhausen, Hannover) war Herzog zu Braunschweig und Lüneburg. Zunächst war er als nachgeborener Prinz für den geistlichen Stand bestimmt und wurde als Ernst August I. Fürstbischof von Osnabrück. 1679 wurde er Fürst von Calenberg und 1692 der erste Kurfürst von Braunschweig-Lüneburg („Kurhannover“).

Clara Elisabeth Gräfin von Platen, geborene von Meysenbug (* 24. Januar 1648 auf Schloss Eilhausen im hessischen Land Waldeck; † in der Nacht vom 30. Januar auf den 31. Januar 1700 auf Schloss Monbrillant im heutigen Welfengarten in Hannover) war die Mätresse des späteren Kurfürsten Ernst August von Braunschweig-Lüneburg und Drahtzieherin in der Königsmarck-Affäre.

Sophia (German: Sophie, [zoˈfiː]; 14 October [O.S. 3 October] 1630 – 8 June [O.S. 28 May] 1714) was Electress of Hanover from 1692 to 1698 as the consort of Prince-Elector Ernest Augustus. She was later the heiress presumptive to the thrones of England, Scotland, and Ireland under the Act of Settlement 1701, as she was the granddaughter of King James VI and I. Sophia died less than two months before she would have become Queen of Great Britain and Ireland. Consequently, her son George succeeded her first cousin once removed, Queen Anne, to the British throne. The succession to the throne has since been composed entirely of, and legally defined as, Sophia's legitimate Protestant descendants.

Sophia was born in The Hague to Frederick V, formerly Elector Palatine and King of Bohemia, and Elizabeth Stuart, daughter of King James I and VI. She grew up in the Dutch Republic, where her family had sought refuge after the sequestration of their Electorate during the Thirty Years' War. During this time, the English Stuarts also went into exile and Sophia was courted by her cousin, Charles II of England.

Sophia instead married Prince Ernest Augustus, her third cousin, in 1658. Despite his temper and frequent absences, Sophia loved him and bore him seven children who survived to adulthood. Born a landless cadet, Ernest Augustus succeeded in having the House of Hanover raised to electoral dignity in 1692. As a result, Princess Sophia became Electress of Hanover, the title by which she is best remembered. A patron of the arts, Sophia commissioned Herrenhausen Palace and its gardens and sponsored philosophers, such as Gottfried Leibniz and John Toland.
