Constitution
The Austro-Hungarian Empire, also known as the Dual Monarchy or the Habsburg Monarchy, was a constitutional monarchy in Central Europe from 1867 until 1918. It was formed after the Austro-Hungarian Compromise of 1867, which established a military and diplomatic alliance between two sovereign states: the Austrian Empire and the Kingdom of Hungary.
The Compromise of 1867 restored the old historic constitution of the Kingdom of Hungary, which had been lost after the Hungarian Revolution of 1848. This revolution, which was ultimately crushed by the Austrian military with support from Russia, sought to end Habsburg rule and gain independence for Hungary. Following the revolution, Hungary was placed under martial law and subjected to absolutist rule from Vienna. German was declared the official language of public administration, and education was placed under state control.
The Austro-Hungarian Empire was a real union between Cisleithania (the northern and western parts of the former Austrian Empire) and Transleithania (the Kingdom of Hungary). Each state had its own parliament and prime minister, and they were co-equal in power. A single monarch, Emperor Franz Joseph I, reigned as both the Emperor of Austria and the King of Hungary.
The Compromise of 1867 put an end to the military dictatorship and absolutist rule over Hungary, restoring the Kingdom of Hungary's territorial integrity and legal and political status. The agreement also restored the reform laws (the April Laws) of the revolutionary parliament of 1848, which established civil and political rights and economic and societal reforms in Hungary.
The dissolution of the Austro-Hungarian Empire began with the Hungarian Parliament's vote in 1918 to terminate the real union with Austria, ending the dual monarchy. This was followed by the proclamation of the Republic of German Austria and the Hungarian Democratic Republic. The Treaty of Saint-Germain-en-Laye and the Treaty of Trianon established the new borders of Austria and Hungary, reducing them to smaller, landlocked states.

Ruler
The Austro-Hungarian Empire, also known as the Dual Monarchy, was a constitutional monarchy that existed between 1867 and 1918. It was a union between the Austrian Empire and the Kingdom of Hungary, with a single monarch who was titled both the Emperor of Austria and the King of Hungary.
The Emperor of Austria and King of Hungary, Franz Joseph I, was the ruler of the Austro-Hungarian Empire from its formation in 1867 until his death in 1916. He was the eldest son of Archduke Francis Charles and Sophia, daughter of King Maximilian I of Bavaria. Franz Joseph became emperor at the age of 18 in December 1848, after his uncle Emperor Ferdinand's abdication due to the revolution.
Franz Joseph's reign was marked by political difficulties and tensions within the empire, particularly with the Slavs. He was a Roman Catholic ruler and a fierce opponent of Freemasonry. His civil administration was highly regarded throughout Europe, and he maintained a unified diplomatic and defence policy between Austria and Hungary.
During the Hungarian Revolution of 1848, the Magyars attempted to sever ties with the Habsburg Dynasty, but their efforts were thwarted by the Austrian Empire with military support from Russia. Franz Joseph instituted a military dictatorship and absolutist rule over Hungary, declaring German as the official language of public administration. However, the Austro-Hungarian Compromise of 1867 ended this dictatorship and restored Hungary's territorial integrity and its old historic constitution.
It is worth noting that while Hungary was technically part of the Austrian Empire, it had its own ruler in the form of the Apostolic King of Hungary. Constitutionally, Franz Joseph's uncle, Emperor Ferdinand, was the legal king of Hungary. However, during the revolution, Lajos Kossuth became the de facto and de jure ruler of Hungary until the collapse of the revolution.

Prime Minister
Austria-Hungary, also known as the Austro-Hungarian Empire, the Dual Monarchy, or the Habsburg Monarchy, was a multi-national constitutional monarchy in Central Europe from 1867 to 1918. It was a military and diplomatic alliance consisting of two sovereign states with a single monarch, who was both the Emperor of Austria and the King of Hungary.
While there was no common prime minister for Austria-Hungary, the two countries did have their own respective prime ministers. For instance, the Austrian Prime Minister Count Kasimir Felix Badeni gave Czech equal standing with German in the internal government of Bohemia. On the other hand, the Hungarian prime minister István Tisza opposed a preventive war against the Serbian nation, which was desired by some members of the Austro-Hungarian government.
In 1917, during the Great War, protests led to the unification of the previous posts of Minister-President of Austria and Prime Minister of Hungary, creating the post of Prime Minister of Austria-Hungary. However, this position was short-lived as Hungary terminated the union with Austria in 1918. Following the dissolution of the union, Count Mihály Károlyi, a prominent opponent of the continued union with Austria, seized power in the Aster Revolution and became the Hungarian prime minister.

Parliament
Austria-Hungary, also known as the Austro-Hungarian Empire, the Dual Monarchy, or the Habsburg Monarchy, was a multi-national constitutional monarchy in Central Europe from 1867 to 1918. It was a union between Cisleithania, the northern and western parts of the former Austrian Empire, and Transleithania, the Kingdom of Hungary.
The Austro-Hungarian Compromise of 1867 established the dual monarchy of Austria-Hungary, which was a military and diplomatic alliance of two sovereign states with a single monarch. The Compromise restored the old historic constitution of the Kingdom of Hungary, which had been lost after the Hungarian Revolution of 1848. The agreement put an end to the 18-year-long military dictatorship and absolutist rule over Hungary by Emperor Franz Joseph.
The Austrian and Hungarian states were co-equal in power and conducted unified diplomatic and defence policies. They maintained separate parliaments, each with its own prime minister: the Diet of Hungary (commonly known as the National Assembly) and the Imperial Council (Reichsrat) in Cisleithania. The Diet of Hungary was bicameral, consisting of the House of Magnates as the upper house and the House of Representatives as the lower house. The Imperial Council was also bicameral, with the House of Lords as the upper house and the House of Deputies as the lower house.
The two parliaments each elected a delegation of 60 members, who met separately and voted on the expenditures of the Ministerial Council, giving the two governments influence in the common administration. However, the ministers ultimately answered to the monarch, who had the final say on foreign and military policy. The Austrian Prime Minister, Count Kasimir Felix Badeni, gave Czech equal status with German in the internal government of Bohemia, causing a crisis due to nationalist German agitation.

Foreign policy
Austria-Hungary, also known as the Austro-Hungarian Empire, the Dual Monarchy, or the Habsburg Monarchy, was a constitutional monarchy in Central Europe from 1867 to 1918. It was a military and diplomatic alliance between two sovereign states, Austria and Hungary, which shared a single monarch titled the Emperor of Austria and the King of Hungary.
Austria-Hungary's foreign policy was largely influenced by its desire to maintain and expand its power and influence in the Balkans, a region marked by rising nationalism and independence movements. The empire's foreign relations and defence policies were managed jointly, while other state functions were handled separately.
In the late 19th century, Count Gyula Andrássy, the Hungarian Foreign Minister, focused on opposing Russian expansion in the Balkans and blocking Serbian ambitions to dominate a South Slav federation. This led to the stationing of Austro-Hungarian troops in Bosnia in 1878 to prevent Russian expansion into Serbia, and the formation of the Mediterranean Entente with Britain and Italy in 1887 to counter Russian influence. Mutual defence pacts were also concluded with Germany in 1879 and Romania in 1883, reflecting a complex web of alliances and treaties aimed at ensuring stability in the region.
In the early 20th century, tensions escalated due to Austria's annexation of Bosnia in 1908 and Serbia's growing ambitions to unite the Slavic people of Southeast Europe. The assassination of Archduke Franz Ferdinand in 1914 by a Bosnian-Serb terrorist provided the spark for war. Austria-Hungary, with German encouragement and support, issued an ultimatum to Serbia, leading to the outbreak of World War I.
During the war, the Hungarian Prime Minister, Count István Tisza, and the Foreign Minister, Count István Burián, had significant influence over the internal and external affairs of the monarchy. Despite initial successes, the Austro-Hungarian Empire suffered severe casualties and eventually collapsed, with Hungary terminating the union with Austria in 1918.
