Ivan the Russian

Ivan the Russian (Bulgarian: Иван Русина, Ivan Rusina; Hungarian: Orosz Iván) (fl. 1288/1323–1332) was a 14th-century Bulgarian military leader of Russian origin who served Bulgarian tsars Michael Shishman and Ivan Alexander. Prior to joining the armed forces of the Second Bulgarian Empire, Ivan the Russian may have been a military commander in the service of the Hungarian governor of Severin.

Ivan the Russian rose to a high rank in the Bulgarian military in the wake of the accession of Michael Shishman to the throne. In 1323, he was in charge of the Bulgarian defence of Plovdiv during the prolonged and ultimately successful Byzantine siege of the city. In 1328, he was involved in a failed Bulgarian attempt to capture the Byzantine capital Constantinople from within. Probably taking part in the turbulent events that surrounded and followed Michael Shishman's death, Ivan the Russian was last mentioned as a representative of Ivan Alexander in 1332.
