The Austro-Hungarian Compromise of 1867 (, ) (alias Composition of 1867) established the dual monarchy of Austria-Hungary. The Compromise re-established partially the sovereignty of the Kingdom of Hungary, separate from, and no longer subject to the Austrian Empire. Under the Compromise, the lands of the House of Habsburg were reorganized as a real union between the Austrian Empire and the Kingdom of Hungary. The Cisleithanian (Austrian) and Transleithanian (Hungarian) regions of the state were governed by separate parliaments and prime ministers. Unity was maintained through rule of a single head of state, reigning as both the Emperor of Austria and King of Hungary, and common monarchy-wide ministries of foreign affairs, defence and finance under his direct authority. The armed forces were combined with the Emperor-King as commander-in-chief.
