Austria-Hungary, often referred to as the Austro-Hungarian Empire or the Dual Monarchy, was a multi-national constitutional monarchy in Central Europe between 1867 and 1918. Austria-Hungary was a military and diplomatic alliance of two sovereign states with a single monarch who was titled both emperor of Austria and King of Hungary. Austria-Hungary constituted the last phase in the constitutional evolution of the Habsburg monarchy: it was formed with the Austro-Hungarian Compromise of 1867 in the aftermath of the Austro-Prussian War and was dissolved shortly after Hungary terminated the union with Austria on 31 October 1918.
