Granddaughter of James I of England, Sophia (1630–1714) began life a penniless princess in exile. She ended it as electress dowager of Hanover, an emerging European power. Had she lived two months longer, she would have succeeded to the British crown before her son, George I. In keeping with Sophia’s reputation as the era’s “most entertaining woman,” her memoirs, which she wrote in French, paint a captivating and often humorous portrait of her life as one of Europe’s preeminent noblewomen and celebrities. They also recall, with insight and verve, her interactions with leading men and ladies (Charles II, Louis XIV, Queen Christina of Sweden) and long-forgotten bit players (cavaliers, concubines, clerics, and quacks). The memoirs, which recount the first fifty years of Sophia’s life, appear here in English for the first time in their entirety. Their publication in this series is particularly timely, as it coincides with the three hundredth anniversary of the Hanoverian succession (2014).
