Chi ha sposato Ernesto Augusto di Brunswick-Lüneburg?

Ernesto Augusto di Brunswick-Lüneburg (Herzberg am Harz, 20 novembre 1629 – Herrenhausen, 23 gennaio 1698) è stato un vescovo luterano tedesco, duca di Brunswick-Lüneburg. Governò sul principato di Calenberg alla suddivisione del ducato paterno. Venne nominato principe-elettore del Sacro Romano Impero nel 1692, ma morì prima che la sua nomina divenisse effettiva. Per quest'ultimo motivo viene da certa storiografia indicato anche come Ernesto Augusto I di Hannover. Fu anche principe-vescovo luterano di Osnabrück dal 1662 fino alla sua morte.

Fu padre di Giorgio I di Gran Bretagna, primo della dinastia degli Hannover ad essere asceso al trono inglese.

Clara Elisabeth, Countess von Platen-Hallermund (14 January 1648 – 30 January 1700, Schloss Monplaisir, in what is now the Von-Alten-Garten in Hannover), was a German noblewoman, most notable as the mistress of Ernest Augustus (Elector of Hanover, father of George I of Great Britain) and for her involvement in the Königsmarck affair.

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.
