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".
Battle of Hochkirch
Although the Seven Years War was a global conflict, it took a specific intensity in the European theater based on the recently concluded War of the Austrian Succession (1740–1748). The 1748 Treaty of Aix-la-Chapelle gave Frederick II of Prussia, known as Frederick the Great, the prosperous province of Silesia. Empress Maria Theresa of Austria had signed the treaty to gain time to rebuild her military forces and forge new alliances; she was intent upon regaining ascendancy in the Holy Roman Empire as well as recovering the Silesian province. In 1754, escalating tensions between Britain and France in North America offered France an opportunity to break the British dominance of Atlantic trade. Seeing the opportunity to regain her lost territories and to limit Prussia's growing power, Austria put aside its old rivalry with France to form a new coalition. Britain aligned herself with the Kingdom of Prussia; this alliance drew in not only the British king's European territories held in personal union, including Hanover, but also those of his relatives in the Electorate of Brunswick-Lüneburg and the Landgraviate of Hesse-Kassel. This series of political maneuvers became known as the Diplomatic Revolution.
