Sava, named after Saint Sava, was born in 1669, in the village of Jasenik near Gacko, Bosnia Eyalet, Ottoman Empire. His father, Luka Vladislavić, was a Serblandlord. The family was driven out from Gacko by the local Turks, and settled in the Republic of Ragusa. Having settled with his family in Ragusa, Luka enrolled Sava in the best schools there. The well-being of the citizens of Ragusa depended on maritime commerce; Sava Vladislavich was no exception. For higher education, Sava was sent abroad, first to the Republic of Venice to study Italian, Latin, philosophy, law, commerce and maritime science, then, to Spain and France where he took advanced courses in international law and commerce which became a great aid to his father's merchant business in Ragusa.
Russian service
A commercial project brought the young merchant to Constantinople, where, in the absence of a permanent Russian mission, he was entrusted with various tasks by the Russian foreign ministersVasily Galitzine and Emelian Ukraintsev. It so happened that his own commercial interests always went hand-in-hand with those of the Russian government. In 1702, he made the acquaintance of Peter the Great in Azov. With an eye toward profiting from the fur trade with Russia, Vladislavich visited Moscow in the next year, but, after obtaining important privileges from the Tsar, returned to Constantinople, where he represented Russia's interests, in tandem with Pyotr Andreyevich Tolstoy, until the Battle of Poltava. It was he who purchased for the Tsar a black page, Ibrahim Hannibal, the ancestor of the great Pushkin. In 1708, he relocated to Moscow and soon received from the Tsar the lands in Little Russia, where Nezhin was made the centre of his commercial operations. The "Illyrian Count" maintained trade contacts with fellow Serbs and was under the impression that they would rise in revolt against the Sultan as soon as the Tsar invaded the Danubian Principalities. Having launched the invasion in 1711, Peter sent him on a mission to Moldavia and Montenegro, whose population Vladislavich was expected to incite to rebellion. Little came of these plans, despite the assistance of a pro-Russian colonel, Michael Miloradovich. There has been preserved an inscription from that time, in a chronicle: From 1716 to 1722, Vladislavich resided in Italy, dividing his time between the advocacy of his own private interests and those of the Tsar. He entertained the aristocracy of Venice as well as foreign visitors, Ernest Louis, Landgrave of Hesse-Darmstadt, Charles I, Landgrave of Hesse-Kassel, Girolamo Colloredo, Governor of the Duchy of Milan, Prince Teodor Konstanty Lubomirski, Anselm Franz, 2nd Prince of Thurn and Taxis, and Count Charachin. It was to this patron that Antonio Vivaldi dedicated La verità in cimento at Venice in 1720. While in Italy, among other commissions, he supervised the education of Russian nobles and prepared important, secret political treaties with Pope Clement XI. It was he who acquired in Venice an assortment of marble statues that still decorate the Summer Garden in St. Petersburg.
In 1725, Vladislavich retraced the steps of Spathari's travels, leading a large Russian mission to negotiate a new treaty with the Qing Empire. The extended and fractious negotiations with the Qing Emperor and his officials resulted in the Treaty of Burya, which adopted the doctrine of Uti Possidetis Juris for delimiting the Russo-Chinese border. In 1728, these provisions were finalized in the Treaty of Kyakhta, which also incorporated Vladislavich's proposal on the construction of an Orthodox chapel in Beijing. Viewing the commonly agreed border as an "everlasting demarcation line between the two empires", Vladislavich spared no effort to further trade and commerce on the border. He personally selected the location for the Russian trade factory of Kyakhta, where the district of Troitskosavsk commemorates his name. As a reward for his part in securing a favourable treaty with China and establishing the Tea Road between the two countries, he was invested with the Order of St. Alexander Nevsky. He also drafted a comprehensive project of financial reform and left a detailed description of the Qing Empire. In a secret memorandum, Vladislavich cautioned the Russian government against ever going to war with China.
Work
In 1722, Sava Vladislavich published his most famous work, a translation in Russian of Mavro Orbin's Il regno de gli Slavi, which included a long passage on Kosovo. It was a tremendous sensation in Russia and the Balkans, and attracted the attention and discussion of all cultured society. It was said that "nowhere was there a rather large library that did not have a copy of Sava Vladislavich's translation of Orbini."
Legacy
According to Serbian poet and diplomat Jovan Dučić, descendant of Sava's either half-brother or first cousin Duka, "Sava Vladislavich occupied a distinguished position among Russian diplomats in the eighteenth century. During two and a half decades, he took part in all important events of the Russian empire as a legate of the Czar and Czarina." The fortress of Troitsko Savsk was named after him at the time when he was negotiating a second treaty in 1727 between Russia and China.
