The Byzantine province of Paristrion along the lower Danube collapsed with the rising of 1185-1186, and its river fortresses passed to the Asen brothers.
On 1 January 1200 the Danube is Kaloyan's northern frontier and his road to his Cuman allies, who cross it in spring and autumn to raid Thrace. Vidin (Bdin) guards the north-west by the Timok; Svishtov and the crossings of the middle river lead into the Yantra country and Tarnovo; Dristra (Silistra), the old metropolis of Paristrion, holds the east and the way into Dobruja. Byzantine Varna on the Black Sea is not his (con).
No commander is named for any of these places.
Who he is
- Name
- not named in any source of 1199-1200
- Title
- Commanders of the tsar's Danube fortresses

- The Danube line fell to the Asen brothers in the first years of the rising (Dristra by 1186, as the Silistra article has it; Vidin not pinned).
- Born
- not pinned
- Family
- not pinned
- Confidence
- low
No governor of Vidin, Dristra or the river forts is named before the mid-13th century; the record is built from the places and the general history of the rising (Second Bulgarian Empire; Silistra; Vidin).
Overlord
Kaloyan.
What it holds
- Vidin (Bdin) and the north-west to the Timok (Vidin).
- The river bank from Lom to Ruse: Lom, Oryakhovo, Nikopol and Svishtov (Svishtov); which of these were fortified in 1200 is not pinned.
- Dristra (Silistra) and southern Dobruja (Dristra).
- Central Dobruja as a claim (see Bulgaria).
How it was acquired
Taken in the rising of 1185-1186 and the years after.
Allies and rivals
The Cumans north of the river (dnb) are allies; Hungary holds the north bank above the Iron Gates (Keve, opposite Braničevo).
How things stand that morning
Held for Kaloyan. The river is frozen or low in winter, when Cuman bands can cross.
Wealth
River tolls and crossings; fisheries; the trade of the Danube; the grain of the plain.
Military
River fortresses of Roman and Byzantine origin (Vidin, Dristra, Svishtov); no garrison figures.
Threats
- Cuman bands crossing on their own account.
- Hungarian pressure upstream.
Where the sources disagree
Evidence: Bulgarian possession is secure in outline (Varna is called the last Byzantine stronghold in Moesia in 1201); names, garrisons and the state of each fort in 1200 are not recorded.
On the map: Blocks drawn round the river towns; the commanders are unknown.

- The Deeds of the Hungarians, by the Anonymous Notary of King Béla, Anonymus (P. magister) (about 1200 to 1210, the date disputed). Not a record of events but a picture of the kingdom's nobility and geography as a courtier of about 1200 wished to see it: the clans and their lands, the castles and counties, the Vlachs, Cumans and other peoples of the Carpathian basin, all projected back onto the conquest.
