SMS Szent István
Montecuccoli's plans for the construction of "Szent István" and her sister ships earned the approval of Emperor Franz Joseph I in January 1909, and by April plans for the design, construction, and financing for the battleships had been laid out. For a full year, the Austro-Hungarian Navy attempted to keep the looming construction of the first two battleships a state secret. This did not prevent rumors from circulating across Europe of two dreadnought battleships being constructed in Austria-Hungary. The French Naval Attaché in Vienna complained to Paris in 1910 of extensive secrecy within the Austro-Hungarian Navy, which manifested itself in several ways. Among these were a ban on photography in the Pola, future home port of "Szent István", and near-constant observation by the Austro-Hungarian police.
Austro-Hungarian Compromise of 1867
In the Middle Ages, the Duchy of Austria was an autonomous state within the Holy Roman Empire, ruled by the House of Habsburg, and the Kingdom of Hungary was a sovereign state outside the empire. In 1526, Hungary was defeated and partially conquered by the Ottoman Empire. King Louis II of Hungary and Bohemia had no legitimate heir and died young in the Battle of Mohács. Louis II's brother-in-law, Ferdinand I of Habsburg was elected King of Hungary by a rump Parliament in Pozsony in December 1526.
The Ottomans were subsequently driven out of Hungary by international Western Christian forces led by Prince Eugene of Savoy between 1686 and 1699. From 1526 to 1804, Hungary was ruled by the Habsburg dynasty as kings of Hungary, but remained nominally and legally separate from the other lands of the Habsburg Monarchy.
