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".
1757 raid on Berlin
After the War of the Austrian Succession, traditional European alliances fell apart and were replaced by an Anglo-Prussian pact and a Franco-Austrian alliance. Known as the Diplomatic Revolution, these events caused the Seven Years' War. Frederick II, King of Prussia and bitter rival of the Holy Roman Empress Maria Theresa of Austria, invaded Silesia in 1756 but suffered his first defeat at Kolin on June 18. In the aftermath of the battle, however, Frederick neglected to protect the approach to his capital, Berlin.
