The King of Hanover (German: König von Hannover) was the official title of the head of state and hereditary ruler of the Kingdom of Hanover, beginning with the proclamation of the King of the United Kingdom George III, as "King of Hanover" during the Congress of Vienna, on 12 October 1814 at Vienna, and ending with the kingdom's annexation by Prussia on 20 September 1866.



In 1813, George III of the United Kingdom was restored to his Hanoverian territories, and in October 1814 they were constituted as the independent Kingdom of Hanover at the Congress of Vienna. The personal union with the United Kingdom ended in 1837 on the accession of Queen Victoria because the succession laws in Hanover, based on Salic law, prevented a female inheriting the title if there was any surviving male heir (in the United Kingdom, a male took precedence only over his sisters).

After the electoral title became defunct, with the dissolution of the Holy Roman Empire in 1806, nonetheless between 1806 and 1814, the dissolution of the Holy Roman Empire was not recognised and George III retained the electoral title until early 1814 when George was proclaimed King of Hanover, a title which was universally recognised during the Congress of Vienna (1814–15).
