 The new kingdom existed from 1815 to 1866, but upon the accession of Queen Victoria (who could not inherit Hanover under Salic law) in 1837, it passed to her uncle, Ernest Augustus, King of Hanover, and thus ceased to be in personal union with the British Crown.The House of Este gave Great Britain and the United Kingdom the "Hanoverian monarchs" (1714–1901).All later generations of the Italian branch are descendants of Fulco d'Este.
