Austro-Italian ironclad arms race
Seizing upon the decline of the Regia Marina in the years immediately after the Battle of Lissa, Tegetthoff worked to continue the efforts of Archduke Ferdinand Max of expanding the ironclad fleet of the now Austro-Hungarian Navy. Tegetthoff found political allies in the Austro-Hungarian Minister of War Carl von Franck and retired Admiral Bernhard von Wüllerstorf-Urbair. Wüllerstorf's and Franck's primary arguments in favor of continuing with the ironclad program Austria had engaged in prior to the Seven Weeks War lay largely along economic grounds. The two believed that constructing new ironclad warships would rejuvenate Austria-Hungary's economy following the defeat at the hands of Prussia and Italy, and that such a fleet would help to open up new commercial opportunities in the Levant and the Middle East. These proposals would be shelved however while Austria continued to reel from the military defeats inflicted by Prussia, and several cabinet reshufflings by Emperor Franz Joseph I resulted in a government more interested in pursuing revenge against Prussia than constructing new ironclads, which would be of little use in a hypothetical second war with Prussia.
History of Austria
In 1745, following the reign of the Bavarian Elector as Emperor Charles VII, Maria Theresa's husband Francis of Lorraine, Grand Duke of Tuscany, was elected Emperor, restoring control of that position to the Habsburgs (or, rather, to the new composite house of Habsburg-Lorraine), Francis holding the titular crown until his death in 1765, but his empress consort Maria Theresa carrying out the executive functions. The Pragmatic Sanction of 1713 applied to the hereditary possessions of the Habsburgs and Archduchy of Austria but not the position of Holy Roman Emperor, which could not be held by women, thus Maria Theresa was Empress Consort not Empress Regnant.
