The Ottoman Empire gave Russia access to the mouths of the Danube and the fortresses of
Akhaltsikhe and
Akhalkalaki in
Georgia. The Sultan recognized Russia's possession of Georgia (with
Imeretia,
Mingrelia,
Guria) and of the Khanates of
Erivan and
Nakhichevan which had been ceded to the tsar by
Persia in the
Treaty of Turkmenchay a year earlier. The treaty opened the Dardanelles to all commercial vessels, thus liberating commerce for grain, livestock and lumber. However, it took the
Treaty of Hünkâr İskelesi (1833) finally to settle the Straits Question between the signatories. Under the Treaty of Adrianople, the Sultan reguaranteed the previously promised autonomy to Serbia, promised autonomy for
Greece, and allowed Russia to occupy Moldavia and Wallachia until the Ottoman Empire had paid a large indemnity. However, under the modifications of the later Treaty of Hünkâr İskelesi, these indemnities were sharply curtailed. The treaty also fixed the border between the Ottoman Empire and Wallachia on the
thalweg of the
Danube, transferring to Wallachia the rule of the
rayas of
Turnu,
Giurgiu and
Brăila. The main sections of the treaty were as follows: • In recognition of the
Treaty of London, the independence of Greece, or autonomy under Ottoman suzerainty, was accepted. • The Ottoman Empire had nominal suzerainty over the Danube states of Moldavia and Wallachia; for all practical purposes, they were independent. • Russia took control of the towns of Anape and Poti in Caucasus. • The Russian traders in Turkey were placed under the legal jurisdiction of the Russian ambassador. == Demographic changes ==
