In October 1585 the electress Anna died, and a few weeks later Augustus married Agnes Hedwig, a daughter of Joachim Ernest, prince of Anhalt.
In 1711 the Princess Palatine wrote to the Electress Sophia of Hanover, and suggested that he was an English nobleman who had taken part in a plot of the duke of Berwick against William III.
In 1701 Toland spent a few weeks at Hanover as secretary to the embassy of the earl of Macclesfield, and was received with favour by the electress Sophia in acknowledgment of his book Anglia Libera, a defence of the Hanoverian succession.
Marlborough's successive victories, and especially the factious conduct of the Tories, who in November 1705 moved in parliament that the electress Sophia should be invited to England, drove Anne farther to the side of the Whigs.
The wish expressed by the Whigs, that a member of the electoral family should be invited to England, had already aroused the queen's indignation in 1708; and now, in 1714, a writ of summons for the electoral prince as duke of Cambridge having been obtained, Anne forbade the Hanoverian envoy, Baron Schutz, her presence, and declared all who supported the project her enemies; while to a memorial on the same subject from the electress Sophia and her grandson in May, Anne replied in an angry letter, which is said to have caused the death of the electress on the 8th of June, requesting them not to trouble the peace of her realm or diminish her authority.
During this period several suburbs had begun to grow up, Friedrichswerder in 1667 and the Dorotheenstadt, so named in 1676 after the electress Dorothea its founder.
Towards the end of the 15th century it passed to Brandenburg, and, in 1684, after a great conflagration which laid it in ruins, was handsomely rebuilt by the electress Dorothea.
Frederick's chief adviser about this time was Eberhard Danckelmann (1643-1722), whose services in continuing the reforming work of the great elector were very valuable; but having made many enemies, the electress Sophia among them, he fell from power in 1697, and was imprisoned for several years.
The elector of Hanover, George Louis, son of the electress Sophia (daughter of Elizabeth, daughter of James I.), peacefully succeeded to the throne as George I.
In addition to those descended from these two marriages there are also the descendants of Edward, a brother of the electress Sophia.
