The Hanoverian dimension in British foreign policy and domestic politics during the final decades of the Personal Union has received little historical attention. The only historian to have specifically focused on the relationship between Britain and Hanover after 1815 confined his analysis largely to the realm of foreign policy and admitted the need for more research. The absence of Hanover from general surveys of British domestic politics is perhaps understandable: the significance of the Personal Union in purely domestic British affairs was spasmodic and haphazard. Nevertheless there was a Hanoverian dimension to British domestic politics after 1815 which manifested itself in public attitudes towards the monarchy, catholic emancipation and the cause of liberty at home and abroad. Hanoverian issues were not constant themes in newspapers, periodicals and political caricature, but nor were they entirely invisible. The omission of the Hanoverian dimension by historians is particularly striking in areas where there seems to be a good prima facie case for taking the Personal Union into consideration.
