The Dual Monarchy of Austria-Hungary was a political arrangement established in 1867 that created a dual system of governance for the Austro-Hungarian Empire, comprising two separate entities: the Kingdom of Hungary and the Austrian Empire. This system allowed both regions to have their own parliaments and administrative structures while being united under a single monarch, Franz Joseph I, who held the title of Emperor of Austria and King of Hungary. The arrangement was a response to rising nationalist sentiments and aimed at balancing the interests of various ethnic groups within the empire.
