Nicholas, too, was convinced that the collapse of the Ottoman Empire was at hand. He was prepared to hasten its demise and liberate the Balkan Christians, provided he could get the other powers, or at least Austria (his closest ally with interests in the Balkans), on his side. As his troops advanced towards the Turkish capital, Nicholas informed the Austrian ambassador in St Petersburg that the Ottoman Empire was ‘about to fall’, and suggested that it would be in Austria’s interests to join Russia in the partition of its territories in order to ‘forestall the people who would fill the vacuum’. The Austrians, however, mistrusted Russia and chose instead to preserve the Concert of Europe. Without their support, Nicholas held back from dealing the fatal blow to the Ottoman Empire in 1829. He was afraid of a European war against Russia should his attack on Turkey move the other powers to unite in its defence, and even more afraid that the collapse of the Ottoman Empire would result in a frantic rush by the European powers to seize Turkish territories. Either way, Russia would lose out. For this reason, Nicholas abided by the viewpoint of his cool and calculating Foreign Minister: that it would best serve Russia’s interests to keep the Ottoman Empire in existence, but in a weakened state, where its dependence on Russia for survival would enable the promotion of Russian interests in the Balkans and the Black Sea area. A sick Turkey was more useful to Russia than a dead one.21
Consequently, the Treaty of Adrianople was surprisingly kind to the defeated Turks. Imposed by the Russians in September 1829, the treaty established the virtual autonomy of Moldavia and Wallachia under Russian protection. It gave the Russians some islands in the mouth of the Danube, a couple of forts in Georgia and the Sultan’s recognition of their possession of the rest of Georgia as well as the south Caucasian khanates of Erivan and Nakhichevan, which they had wrested from the Persians in 1828, but compared to what the Russians might have forced out of the defeated Turks, these were relatively minor gains. The two most important clauses of the treaty secured concessions from the Porte that had been wanted by all the signatories of the Treaty of London: Turkish recognition of Greek autonomy; and the opening of the Straits to all commercial ships.
The Western powers did not trust these appearances of Russian moderation, however. The treaty’s silence on warship movements through the Straits led them to conclude that Russia must have gained some secret clause or verbal promise from the Turks, allowing them exclusive control of this crucial waterway between the Black Sea and the Mediterranean. Western fears of Russia had been growing since the outbreak of the Greek revolt, and the treaty fuelled their Russophobia. The British were especially alarmed. Wellington, by now the Prime Minister, thought the treaty had transformed the Ottoman Empire into a Russian protectorate – an outcome worse than its partition (which at least would have been done by a concert of powers). Lord Heytesbury, the British ambassador in St Petersburg, declared (without any intended irony) that the Sultan would soon become as ‘submissive to the orders of the Tsar as any of the Princes of India to those of the [East India] Company’.22 The British may have totally supplanted the Mughal Empire in India, but they were determined to stop the Russians doing the same to the Ottomans, presenting themselves as the honest defenders of the status quo in the Near East.
Fearful of the perceived Russian threat, the British began to shape a policy towards the Eastern Question. To prevent Russia from gaining the initiative in Greece, they gave their backing to the independence of the new Greek state, as opposed to mere autonomy under Turkish sovereignty (which they feared would make it a dependant of Russia). British fears were not unwarranted. Encouraged by the Russian intervention, Kapodistrias had been calling on the Tsar to expel the Turks from Europe and create a larger Greece, a confederation of Balkan states under Russian protection, on the model once proposed by Catherine the Great. However, the Tsar’s position was seriously weakened by the assassination of Kapodistrias in 1831, followed by the decline of his pro-Russian party and the rise of new Greek liberal parties aligned with the West. These changes moderated Russian expectations and cleared the way for an international settlement at the Convention of London in 1832: the modern Greek state was established under the guarantee of the great powers and with Britain’s choice of sovereign, the young Otto of Bavaria, as its first king.
