Roman Mikhailovich the Old[1] (c. 1218 – after 1288)[1] was a Rus' prince of the Olgovichi clan.
He was Prince of Bryansk (1246 – after 1288), and probably also Prince of Chernigov (1246/7 – after 1288), although most primary sources only mention him as Prince of Bryansk.
[1] Roman was the second son of Mikhail Vsevolodovich of Chernigov (who later became prince of Chernigov, and grand prince of Kiev) by his wife, Elena Romanovna[1] (or Maria Romanovna), a daughter of prince Roman Mstislavich of Halych.
His mother most likely persuaded her husband to name their second son after her father.
[1] Around 1243, Roman’s elder brother, Rostislav Mikhailovich was disowned by their father when he decided to stay in Hungary.
