Sinope, on its isthmus with a harbour on each side, is the best port of the southern Black Sea and the crossing point to the Crimea.
The Seljuks took it in 1081 and Alexios I soon recovered it; under the Komnenoi it prospered. On 1 January 1200 it is imperial, the head of the province that the partition of 1204 calls 'Oinaion, Sinope and Pavrae (Bafra)'. Its hinterland beyond the coastal mountains is Turkish (Kastamon and the Halys valley are the Seljuks'), and the Seljuk port of Amisos (Samsun), which Kilij Arslan II gave to his son Rukn al-Din in the division of his lands, lies about 125 km to the south-east.
Its governor is not named. After 1204 David Komnenos holds it for Trebizond, and the Seljuks take it in 1214 (later).

No officer of this town is named for 1199-1200 in Choniates or in the modern accounts read.
Lord in 1200
Alexios III, through the governor of the province of Oinaion, Sinope and Pavrae (not named).
Overlord
The emperor Alexios III Angelos, through the governor (doux) of the province (thema) and his tax officials.
How things stand that morning
Imperial; an enclave on the coast, Turkish land behind it.
Threats
- The Seljuks, who want a Black Sea port of their own besides Amisos (they take Sinope in 1214)
Charter
None in the western sense. A Byzantine town has no charter of liberties: it is governed by the emperor's officers, and its notables (archontes) and bishop deal with them.
Council
No sworn commune or council. The leading townsmen (archontes) and the bishop or metropolitan speak for the town before the governor.
Communities
Greeks; the metropolitan (archbishop) of Sinope.
Militia
Townsmen man the walls in a siege; the field troops are the governor's and the emperor's.
Walls and castle
Walls across the isthmus and round the town, rebuilt under the Komnenoi after 1081 (not pinned in detail).
Trade and crafts
Black Sea shipping and the crossing to the Crimea (Cherson, Sougdaia); fish; timber. In 1200 the Seljuk interior trades through Amisos rather than through Sinope.
What the year holds
What happened next, if nothing in play changes it. Each event carries what it depends on and what would stop it.

Where the sources disagree
Evidence: Status well established by the 1204 province list and the 1214 conquest; the 1190s are blank.
On the map: Town and its peninsula; the province is drawn by Sinope.
