Claim: In 1866, Hannover (capital and largest city of the German state of Lower Saxony) triumphed and annexed by Prussia at the end of the Austro-Prussian War, and as a result, Prussia dissolved the three Hanoverian orders of knighthood.
Evidence: Hanover (/ˈhænoʊvər, -nəv-/; German: Hannover [haˈnoːfɐ (listen); Low German: Hannober) is the capital and largest city of the German state of Lower Saxony. Along with the rest of Prussia, Hanover became part of the German Empire upon the unification of Germany in January 1871. During the Austro-Prussian War (1866), Hanover attempted to maintain a neutral position, along with some other member states of the German Confederation. The outcome of the war led to the dissolution of Hanover as an independent kingdom and it was annexed by the Kingdom of Prussia, becoming the Prussian Province of Hanover.
