Sophia of Hanover (born Princess Sophia of the Palatinate; 14 October 1630 – 8 June 1714) was the Electress of Hanover by marriage to Elector Ernest Augustus and later the heiress presumptive to the thrones of England and Scotland (later Great Britain) and Ireland under the Act of Settlement 1701, as a granddaughter of James VI and I. Princess Sophia died less than two months before she would have become Queen of Great Britain. Consequently, her son (and grandson of Elizabeth Stuart, Queen of Bohemia) George I, succeeded her first cousin once removed, Queen Anne, to the British throne, and the succession to the throne has since been defined as, and composed entirely of, her legitimate and Protestant descendants.
