Austro-Italian ironclad arms race
In the years after Ferdinand Max's departure from Austria, the Imperial Austrian Navy suffered under further political and budgetary constraints. In April 1864, it was proposed that the naval ministry, which the former Archduke had helped to establish, be disbanded. In January 1865, Emperor Franz Joseph I dissolved the ministry and the Imperial Austrian Navy was again placed under the jurisdiction of the Austrian Ministry of War. Under the 1865 budget, just 7,100,000 Florins were allocated towards naval expenses, but once more, none of the funds were designated for warship construction. In 1866, the naval budget grew slightly to 7,800,000 Florins, but for the third consecutive year there would be no funds for additional ironclads, or other warships. Thus, when the Seven Weeks War began in June 1866, the Imperial Austrian Navy would possess only ships which had been constructed during Ferdinand Max's tenure as "Oberkommandant der Marine".
Silesian Wars
Peace with Prussia allowed the Austrians and their British–Hanoverian allies to reverse the gains made by the French and Bavarians in 1741. By the summer of 1743, Austria recovered control of Bohemia, drove the French back across the Rhine into Alsace, and occupied Bavaria, exiling the Bavarian Elector Charles Albert (now crowned Holy Roman Emperor Charles VII) to Frankfurt. In September 1743, Britain, Austria and Savoy–Sardinia concluded a new alliance under the Treaty of Worms that led Frederick to suspect that Maria Theresa meant to retake Silesia as soon as the war elsewhere was concluded. So, on 7 August 1744 Prussia declared its intervention in the Austrian war on behalf of Bavarian Emperor Charles, and Frederick led soldiers across the frontier into Bohemia on 15 August 1744, beginning the Second Silesian War.
