Count Savva Lukich Raguzinsky-Vladislavich, also known as Sava Vladislavić Raguzinski, was born on January 16, 1669, in Ragusa and died on June 17, 1738, at the Matoksa estate in the Saint Petersburg province. He was a Ragusan merchant and served in the Russian diplomatic service. Raguzinsky headed the Russian embassy in China and founded the city of Troitskosavsk, now known as Kyakhta. He also became famous for his works on economic topics.

Raguzinsky came from a Serbian noble family from the Ragusan republic, which gave him the nickname "Raguzinsky." In his youth, he engaged in trade in France, Spain, and Venice.

He began his diplomatic career in Russia in Constantinople, where he carried out unofficial assignments for V. V. Golitsyn and E. I. Ukrainets. In 1703, he visited Moscow for the first time, where Peter I granted him a charter for ten years, providing him the right to free trade in Russia on par with Russian merchants, a monopoly on the sale of fox fur from the Siberian order, and the right to import and export goods. In 1703 and 1708, he was a secret agent for the Ukrainian hetman I. Mazepa in Turkey.

In 1708, he settled in Moscow and initiated the minting of changeable copper coins. In 1710, he received the rank of court councilor, and in 1711, he represented Russia in Montenegro and Moldavia, supporting the idea of the Prut campaign to liberate the Slavs of the Balkan Peninsula from Turkish oppression.

In 1716 and 1722, representing Peter I, he conducted negotiations in Rome and Venice. On behalf of Peter I, he ordered sculptures for the Summer Garden in Italy, sent Italian specialists to Saint Petersburg, as well as tools and instruments for Peter's workshop. As a gift from the Pope, he received the ancient statue of Venus of Tauris, which is now kept in the Hermitage.

In 1725, Raguzinsky was appointed the plenipotentiary ambassador of Russia to Qing China, where he successfully concluded the Burinsky Treaty and based on it, the Kyakhta Treaty. After returning to Petersburg in 1728, he was awarded the Order of Saint Alexander Nevsky and promoted to actual state councilor. He prepared a detailed memorandum for the Russian government about the Qing Empire and participated in negotiations regarding Russian-Qing trade.

Raguzinsky died at the Matoksa estate and was buried in the Annunciation Church of the Alexander Nevsky Lavra, where a memorial plaque was installed in his honor on September 24, 2010. The first monument to him was erected in June 2011 in Shlisselburg.
