Talks were held at Akkerman to settle the questions left open with Russia after the Treaty of Bucharest (1812). According to the TDV article on Akkerman, the convention signed on 7 October 1826 by M. S. Vorontsov and A. I. Ribeaupierre for Russia and Hadi Pasha and Köse İbrahim Pasha for the Ottomans recognised Serbian autonomy and Russian influence in the Balkans. According to the TDV article on the Straits question, it also confirmed commercial passage through the Straits and free trade in the Black Sea. According to the TDV article on Mahmud II, although Russia had settled the pending questions at Akkerman to its liking and gained important rights, it soon declared war again on the pretext of the Greek question (1828).
