Portugal and Bavaria 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.
Congress of Hanover After their return home, Vergennes and his uncle were now in favour with the French Foreign Minister
Puiseulx. When Chavigny met
Louis XV at
Versailles, he lobbied for Vergennes to be given an appointment. In 1750 Vergennes was appointed as Ambassador to the
Electorate of Trier, one of the smaller German electorates. Vergennes faced an immediate challenge, as the British were planning to have an Austrian candidate
Archduke Joseph elected as
King of the Romans, a position that designated the next Holy Roman Emperor. The Austrians had supplied the Emperors for centuries until 1740, when Charles VII of Bavaria had been elected triggering the War of the Austrian Succession. The title eventually came back under Austrian control, and in 1748 the
Treaty of Aix-la-Chapelle was agreed, bringing peace. The British strategy was directed by the
Duke of Newcastle, the
Northern Secretary and brother of the Prime Minister. Newcastle hoped the election would prevent a recurrence of the recent war, by guaranteeing continued Austrian dominance in Germany. The French saw the proposal as part of a scheme by the British to boost their own power in Germany. Vergennes appointment was designed to frustrate the British plan, and Trier was considered a good strategic spot for this mission. He worked at getting the ruler of Trier to withhold his vote from Joseph, while mobilising wider resistance. In 1752 an attempt to settle the matter, Newcastle travelled to Hanover where
a special Congress was convened. In April 1752 Vergennes was appointed as envoy to
George II of Great Britain in his separate role as
Elector of Hanover. His task was to uphold French interests at the Congress, either by delaying the election or preventing it entirely. To enable this, France championed the claims of the French-allied
Palatine for payment of money they claimed against Austria and Britain insisting it be settled before the election took place. The British eventually agreed to a settlement, but Austria refused to accept this, creating a rift between the two countries which endangered the
Anglo-Austrian Alliance. Newcastle was ultimately forced to dissolve the Congress and abandon the election. The Congress was regarded as a diplomatic triumph for Vergennes and he received praise from Newcastle for his skills. To counter a last attempt by Austria to get an agreement, Vergennes was sent to the Palatine in January 1753 where he secured confirmation that they would stick to France's strategy. He then returned to Trier where he spent fourteen quiet months before he was given his next posting. His time in Germany shaped his views on diplomacy. He was critical of the British tendency of bowing to public opinion because of their democracy, and he was concerned by the rising power of Russia.

Istanbul His successful advocacy of French interests in Germany led him to believe his next posting would be as Ambassador to Bavaria. Instead, he was sent to the
Ottoman Empire in 1755, first as
minister plenipotentiary, then as
full ambassador. The reason for Vergennes' original lesser rank was that sending a new ambassador was a time-consuming elaborate ceremony, and there was a sense of urgency because of the death of the previous ambassador. Before he left France, he was inducted into the
Secret du Roi. Vergennes arrived in
Constantinople as the
Seven Years' War was brewing and
Osman III had recently come to the throne. The Ottomans were traditional allies of the French and were a major trading partner, but the weakening of Ottoman power and the growth of Russia threatened the old system. Despite their close ties, the two states had no formal alliance. In his official orders, Vergennes was ordered not to agree any treaty, but he received secret instructions from the king to agree a treaty if it supported the king's schemes in Eastern Europe. Vergennes's task was to try to persuade the Ottomans to counter the Russian threat to Poland, working in conjunction with
Prussia. The
Diplomatic Revolution of 1756 turned that scheme upside down as France became friendly to and then allied to Austria and Russia and an enemy of Prussia, which forced Vergennes to reverse his anti-Russian rhetoric. The Ottoman leadership were angered by the new
Franco-Austrian Alliance, which they saw as hostile towards them. Vergennes spent the next few years trying to repair relations and persuade the Turks not to attack Austria or Russia, as they were being urged to do by Prussian envoys. in 1755,
Pera Museum,
Istanbul Towards the end of the Seven Years' War, Vergennes tackled several new problems. A dramatic reversal of Russian policies following the succession of
Peter III forced Vergennes to return to his previous policy of encouraging anti-Russian sentiment, only to change again when Peter was overthrown by his wife,
Catherine. Vergennes also had to deal with the consequences of the theft of the Sultan's
flagship by Christian prisoners, who took it to
Malta. The Sultan threatened to build up a large fleet and invade the island, potentially provoking a major war in the Mediterranean in which France would have to defend Malta in spite of the global war that it was already fighting. Eventually, a compromise was agreed in which the French negotiated the return of the ship, but not the prisoners, to the Sultan. The
Treaty of Paris in 1763 brought an end to the war, but France was forced to cede significant territory to the British, easing some of the strains on Vergennes. However, he was left personally disappointed by the decline in French prestige. He was also alarmed by the weakening of French influence in
Poland, which, in 1764, elected
Stanislas Poniatowski, a Russian-backed candidate, as its king after it became apparent that France was powerless to prevent it. Vergennes's efforts to convince the Ottomans to intervene in the election were undermined by a failure to settle on a single French candidate for the throne, and both France and the Ottomans were eventually forced to acknowledge Stanislas as king. As he was a lover of Catherine the Great, it was believed that Poland would become a
satellite of Russia or even that the two states might be merged.
Marriage and recall In 1768, he was recalled, ostensibly because he married the widow Anne Duvivier (1730–1798), also known as de Viviers; -->. She was widowed at the age of 24, before she met Charles Gravier, and they had two daughters together. The painter
Antoine de Favray who was living in Istanbul at this time painted Charles Gravier's wife, Annette Duvivier, Comtesse de Vergennes, in an oriental costume, sitting on a divan, shortly before they married. However, Charles Gravier was more probably recalled because the
Duc de Choiseul thought him not competent to provoke a war between
Imperial Russia and the Ottomans, which Choiseul hoped for. Choiseul wanted to weaken the power of Russia as he believed they were becoming too strong in the
Baltic Sea. Choiseul regarded the best way of doing that as provoking a costly war between them and the Ottomans. Although he thought the strategy unwise, Vergennes continuously advocated war in Constantinople by trying to convince the Ottomans that war was the only way to check Russia's rising power. Vergennes's marriage had taken place without the King's consent, which was a requirement for French ambassadors. In France Vergennes encountered strong disapproval of his marriage and was aware that he returned home in disgrace. In spite of his doubts, Vergennes was successful in persuading the Ottomans to declare war against Russia, and in 1768 the
Russo-Turkish War broke out. It eventually ended in a decisive victory for the Russians, who gained new territory, and further eroded Ottoman power. Despite his opposition to the policy, Vergennes still took credit in France for having fulfilled his orders to provoke a war. During this period Vergennes and Choiseul developed a mutual dislike of each other.
Sweden After Choiseul's dismissal in 1770, Vergennes was sent to
Sweden with instructions to help the pro-French
Hats faction with advice and money. The
revolution of 1772 by which
King Gustav III secured power (19 August 1772) was a major diplomatic triumph for France and brought to an end the Swedish
Age of Liberty, which brought back the absolute monarchy in Sweden. ==Foreign minister==
