Later Frederick III.
After the Prussian victory in its war with Austria and its allied German states in July 1866, the German confederation was dissolved and Hanover, among other entities, was incorporated into the Prussian-dominated North German Confederation. The Guelph dynasty was deposed and its landed wealth sequestrated by Bismark's administration. The Hanoverian army had surrendered on 29 June. (C. Clark (2006), pp. 531-46, 684).
Formal Prussian annexation of Hanover as a province took place on 30 September 1866; the first Prussian-imposed Oberpräsident of Hanover was Otto Graf zu Stolberg-Wernigorode. The North German Confederation Reichstag met in Berlin, not in Hanover.
