Austria-Hungary, also referred to as the Austro-Hungarian Empire, the Dual Monarchy or the Habsburg Monarchy, was a multi-national constitutional monarchy in Central Europe between 1867 and 1918. A military and diplomatic alliance, it consisted of two sovereign states with a single monarch who was titled both the Emperor of Austria and the 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, following wars of independence by Hungary in opposition to Habsburg rule. It was dissolved shortly after Hungary terminated the union with Austria in 1918.
