Šćepan Mali (Serbian Cyrillic: Шћепан Мали pronounced [ɕt͡ɕɛ̂paːn mâːli]; c. 1739 – 22 September 1773), translated as Stephen the Little, was the first and only "tsar" of Montenegro, ruling the country as an absolute monarch from 1768 until his death. Of unclear origins, Šćepan became the ruler of Montenegro through a rumour that he was in fact the deposed Russian emperor Peter III, who had died several years before Šćepan surfaced in the Balkans.
Šćepan arrived in Montenegro in the autumn of 1766. Whether Šćepan was his real name is unknown, as is the reason for the epithet Mali. Who started the rumour that Šćepan was Peter and why is also unclear. Šćepan himself never formally proclaimed himself to be Peter, but never denied it either. Throughout 1767, he offered vague hints that he was the dead emperor, and as time went on, most of Montenegro became convinced of his supposed identity. Although Montenegro's legitimate ruler, Prince-Bishop Sava, who had met the real Peter and had received word from the Russian ambassador in Constantinople that Peter was dead, attempted to expose Šćepan, most Montenegrins continued to believe the rumours. In 1767, Šćepan was proclaimed as the country's ruler, and in February 1768, Sava was sidelined and confined to his monastery. Šćepan subsequently assumed the powers of an absolute monarch.
