Rurik's young nephew, already known as a fighter against the Cumans, holds (or held in the 1190s) Trepol, the fort at the mouth of the Stugna that guards the Dnieper crossing and the approach to Kiev from the steppe.
He is a younger kinsman with a small town and a large reputation to come.
Who he is
- Name
- Mstislav Mstislavich
- Title
- Prince of Trepol (not pinned for 1200)
- Since
- The 1190s (he is called prince of Trepol in the Kievan Chronicle's accounts of the Cuman wars, about 1193; en.wikipedia: 'one of its rulers was Mstislav Mstislavich')
- Born
- not pinned (usually put in the 1170s)
- Family
- Son of Mstislav Rostislavich the Brave (died 1180), Rurik's brother, so Rurik's nephew. His marriage to Maria, daughter of the Cuman khan Kotian, is dated by en.wikipedia only to 'after 1193'.
- Confidence
- low
Praised for bravery in the Cuman wars in 1193 (en.wikipedia). Later prince of Torchesk (by 1206), Toropets (by 1209), Novgorod (1210-1215, 1216-1218) and Galich. Trepol in 1195 was one of the five towns given to Roman and then to Vsevolod, so whether Mstislav still held it on 1 January 1200 is not pinned.
Overlord
His uncle Rurik.
What it holds
- Trepol at the Stugna mouth (Trepol), not pinned for 1200
How it was acquired
From his uncle, in the 1190s (not pinned).
Allies and rivals
His uncle Rurik and cousins; the Cumans as enemies (and through his later marriage, kin).
How things stand that morning
Probably at Trepol under Rurik; not pinned.
Wealth
Trepol's crossing and market.
Military
A small retinue; Trepol's fort.
Threats
- The Cumans
- Roman's war with Rurik
Where the sources disagree
- Trepol was in the 1195 grant to Roman and then to Vsevolod; Mstislav's tenure after 1195 is not checked.
Evidence: His holding of Trepol in the 1190s rests on the Kievan Chronicle as summarised in modern works; not re-checked against the text.
On the map: Low confidence for 1200.
