Prussia materialized its new-found hegemony in Northern Germany by founding the North-German Confederacy. All German states north of the river Main became members. Hesse-Rhine became a member only for the northern part of its territory. The Presidency of the Federation was given to the King of Prussia. A bicameral Federal Parliament (Bundersrat and Reichstag) was founded. Bismarck became Federal Chancellor. On this map, the members of the Confederacy are all depicted in the yellow colour previously used for Prussia. The German Realm, that came forth from the Confederacy, will also be yellow on the following maps. The Austrian Empire concluded its "Ausgleich" or compromise with the Hungarians of the Empire. A Dual Monarchy was established. Carved from the surrounding remnants of the Austrian Empire, the Kingdom of Hungary, that was abolished when the Austrian Empire was established in 1804, was revived. Both states, Empire and Kingdom formed a political and personal union, in which both parties were completely equal and had their own say in the foreign policy and defence of what was to be known as the Dual Monarchy. The Hungarians were mostly appeased, but the Slav peoples of both Realms were not. This would become a great problem for the Dual Monarchy in the age of nationalism where a Pan-Slav movement was aspiring for the liberation of Slav peoples in both Austria and Turkey, under Russian leadership. Austria-Hungary was already in rivalry with Russia over the Balkans, still ruled by the waning Ottoman Empire.
