Sofronije Jugović-Marković (fl. 1789) was a Habsburg Serb writer and activist in Russian service, who envisaged the formation of a Serbian protectorate of Russia (similar to Georgia), that would have held all South Slavic territories of the Habsburg stretching to Istria. Jugović sought to crown Grand Duke Konstantin Pavlovich "Serbian and Bulgarian Tsar Konstantin Nemanjić", after the medieval Nemanjić dynasty. It would continue the legacy of the Serbian Empire.
