WALACHIA, or Wallachia, a former principality of southeastern Europe, constituting, after its union with Moldavia on the 9th of November 1859, a part of Rumania.
Akerman, by which the autonomy of Moldavia,Walachia and Servia was confirmed, free passage of the straits was secured for merchant ships and disputed territory on the Asiatic frontier was annexed, and in July 1827 he signed with England and France the treaty of London for the solution of the Greek question by the mediation of the Powers.
Here, on the 14th of September 1829, was signed a treaty by which the Porte ceded to Russia the islands at the mouth of the Danube and several districts on the Asiatic frontier, granted full liberty to Russian navigation and commerce in the Black Sea, and guaranteed the autonomous rights previously accorded to Moldavia, Walachia and Servia.
Two years after his accession Mahommed overcame a rebellion of the prince of Karamania and recaptured his stronghold Konia (1416), and then, turning northwards, forced Mircea, voivode of Walachia, who in the dispute as to the succession had supported Prince Mussa, to pay tribute.
Peace was also made at the same time with the despot of Servia and the voivode of Walachia, on the basis of the payment of tribute.
