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".
Charles Gravier, comte de Vergennes
The objective of Chavigny and Vergennes in Lisbon was to keep Portugal from entering the War of the Austrian Succession on the side of Britain, a task that proved relatively easy as the Portuguese had little interest in joining the war. In 1743 Vergennes accompanied his uncle to the court of Charles VII who was the ruler of Bavaria and also held the title of Holy Roman Emperor. Charles VII was a key ally of the French in the ongoing war against Austria, and they were charged with keeping him in the war by assuaging his concerns which they accomplished successfully. They next were instrumental in the agreement of the Union of Frankfurt, a pact involving several German rulers to uphold Charles VII's interests. after Charles VII's sudden death in 1745, they strove to help his successor Maximilian III but were unable to prevent him from losing his capital at Munich and making peace with the Austrians at the Treaty of Füssen. In November 1745 Chavigny was relieved of his post, and returned to France accompanied by Vergennes. The following year they returned to Portugal to take up their previous posts there where they remained until 1749, unsuccessfully trying to negotiate a commercial treaty.
