was still the legitimate king of Hanover. His only son, Ernest Augustus, Crown Prince of Hanover, inherited this claim upon George's death in 1878. Ernest Augustus was also first in line to the throne of the Duchy of Brunswick, whose rulers had been a junior branch of the House of Hanover. In 1884, that branch became extinct with the death of William, a distant cousin of Ernest Augustus. However, since Ernest Augustus refused to renounce his claim to annexed Hanover, the Bundesrat of the German Empire ruled that he would disturb the peace of the empire if he ascended the throne of Brunswick. As a result, Brunswick was ruled by a regency until 1913, when his son, also named Ernest Augustus, married the German Emperor's daughter, Princess Viktoria Luise and swore allegiance to the German Empire.

The German-Hanoverian Party, which at times supported secession from the Reich, demanded a separate status for the province in the Reichstag. The party existed until banned by the Nazi government.

The state saw itself in the tradition of the kingdom. Its Prime Minister, Hinrich Wilhelm Kopf, played a central role when the state of Lower Saxony was founded just a few months later by merging Hanover with several smaller states, with the city of Hanover as its capital. The former territory of Hanover makes up 85 percent of Lower Saxony's territory,{ and the coat of arms is derived from it.

Regional consistories supervised church and clergy. These were in Aurich, a simultaneously Lutheran and Calvinist consistory dominated by Lutherans (for East Frisia) and the Lutheran consistories in Hanover (for the former Electorate of Brunswick-Lüneburg proper), in Ilfeld (for the , a Hanoverian exclave in the Eastern Harz mountains), in Osnabrück (for the former Prince-Bishopric of Osnabrück), in Otterndorf (existed 1535–1885 for the Land
