 The Treaty of Adrianople, signed on September 14, 1829, confirmed both the Russian victory and the provisions of the Akkerman Convention, partly amended to reflect the Russian political ascendancy over the area.Furthermore, Wallachia's southern border was settled on the Danube thalweg, and the state was given control over the previously Ottoman-ruled ports of Brăila, Giurgiu, and Turnu Măgurele.The freedom of commerce (which consisted mainly of grain exports from the region) and freedom of navigation on the river and on the Black Sea were passed into law, allowing for the creation of naval fleets in both Principalities in the following years, as well as for a more direct contact with European traders, with the confirmation of the Moldavia and Wallachia's commercial privileges first stipulated at Akkerman (alongside the tight links soon established with Austrian and Sardinian traders, the first French ships visited Wallachia in 1830).
