Austro-Prussian War
The Austro-Prussian War (also known by many other names like the Seven Weeks' War, German Civil War, Brothers War or Fraternal War, known in Germany as  ("German War"),  (; "German war of brothers")) was a war fought in 1866 between the Austrian Empire and the Kingdom of Prussia. Each side was helped by many allies in the German Confederation. Prussia had also allied with the Kingdom of Italy. This connected the conflict to the Third Independence War of Italian unification.
