the Empire's wars, Ernest Augustus was made an Elector of the Holy Roman Empire in 1692. George's prospects were now better than ever as the sole heir to his father's electorate and his uncle's duchy. Sophia Dorothea had a second child, a daughter named after her, in 1687, but there were no other pregnancies. The couple became estranged—George preferred the company of his mistress, Melusine von der Schulenburg, and Sophia Dorothea had her own romance with the Swedish Count Philip Christoph von Königsmarck. Threatened with the scandal of an elopement, the Hanoverian court, including George's brothers and mother, urged the lovers to desist, but to no avail. According to diplomatic sources from Hanover's enemies, in July 1694, the Swedish count was killed, possibly with George's connivance, and his body thrown into the river Leine weighted with stones. The murder was claimed to have been committed by four of Ernest Augustus's courtiers, one of whom, Don Nicolò Montalbano, was paid the enormous sum of 150,000 thalers, about one hundred times the annual salary of the highest-paid minister. Later rumours supposed that Königsmarck was hacked to pieces and buried beneath the Hanover palace floorboards. However, sources in Hanover itself, including Sophia, denied any knowledge of Königsmarck's whereabouts. George's marriage to Sophia Dorothea was dissolved, not on the grounds that either of them had committed adultery, but on the grounds that Sophia Dorothea had abandoned her husband. With her father's agreement, George had Sophia Dorothea imprisoned in Ahlden House in her native Celle, where she stayed until she died more than thirty years later. She was denied access to her children and father, forbidden to remarry and only allowed to walk unaccompanied within the mansion courtyard. She was, however, endowed with an income, establishment, and servants, and allowed to ride in a carriage outside her castle under supervision. Melusine von der Schulenburg acted as George's hostess openly from 1698 until his death, and they had three daughters together, born in 1692, 1693 and 1701. Electoral reign Ernest Augustus died on 23 January 1698, leaving all of his territories to George with the exception of the Prince-Bishopric of Osnabrück, an office he had held since 1661. George thus became Duke of Brunswick-Lüneburg (also known as Hanover, after its capital) as well as Archbannerbearer and a Prince-Elector of the Holy Roman Empire. His court in Hanover was graced by many cultural icons such as the
