The emperor's governor at Thessalonica, the empire's second city, commands its garrison, judges its cases and oversees the taxes, which officials (praktores) and tax farmers collect.
His district (the old theme of Thessalonica) runs from the lower Axios (Vardar) to the Strymon district and down into the Chalkidike peninsulas, with Kalamaria and the Langadas basin; the Holy Mountain is outside it, under the monks' own council. Inside it lie great estates of the Athonite monasteries and of the churches of the city, and grants of revenue to soldiers (pronoia). The city was sacked by the Normans in 1185 and recovered within the year; by 1199 its trade and its October fair are running again.
From the early 11th century the theme of Thessalonica also took in Thessaly, but by 1200 the old themes had broken into small fiscal districts, and whether the governor at Thessalonica still had any say in Thessaly is not pinned. The holder on 1 January 1200 is not pinned.
Who he is
- Title
- Governor (doux) of Thessalonica
- Since
- not pinned
- Confidence
- low
No governor is named in the sources reached for 1196-1203. The last famous holder is David Komnenos, who lost the city to the Normans in August 1185. The Life of St Theodora of Arta says John Petraliphas was sent by Isaac II to govern 'Thessaly and Macedonia'; his tenure is undated and may not have included the city.
Overlord
Alexios III
What it holds
- Thessalonica, its citadel and garrison
- the suburbs and the plain to the Axios
- Kalamaria, the coast toward Chalkidike, thick with monastic estates
- the Langadas basin and the roads north
- Chalkidike: Kassandra with the fort at its isthmus (Kassandreia), Sithonia and the land round Hierissos (the Holy Mountain itself governs itself)
- Pieria under Olympus, with Kitros (its attachment to this district is not pinned)
- the imperial mint at Thessalonica
- perhaps the 'province of the Vardar' (Provintia Vardarii) listed in 1204 and otherwise unattested, which may be the lower Vardar plain
How it was acquired
An office in the emperor's gift, held at his pleasure.
Allies and rivals
Works with the archbishop (Constantine Mesopotamites, a fallen minister now in his see), the city notables (archontes), the Athonite monasteries and their exemptions, and the Venetian merchants privileged by the chrysobull of November 1198. Neighbour to the north: Chrysos at Strumica and Prosek, at peace.
How things stand that morning
Byzantine and quiet; no fighting in the district that winter.
Wealth
Customs and market dues of Thessalonica and its October fair; the land tax of a rich grain and wine district, much of it exempt church and monastic land.
Military
The walls and citadel of Thessalonica, repaired after 1185 (extent not pinned); the fort at the isthmus of Kassandra; Hierissos. Garrison size not recorded.
Threats
- Bulgarian and Cuman raiding if the frontier breaks (Asen's army reached Serres in 1195-1196)
- Chrysos's Vlachs on the Strumica and Vardar roads
- The memory of 1185: a fleet from Sicily
- Venetian privileges eating into the customs
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.
- October 1200, around the feast of St Demetrius on 26 OctoberThe Demetria fair outside the walls.Depends on: Peace on the roads and the sea. Stopped by: War reaching the plain, or pirates closing the sea lanes.
- 1201 (Varzos; some accounts say 1200-1201)Kamytzes, freed by Chrysos's ransom and embittered by the emperor's refusal to help him, rises with his son-in-law: Chrysos takes Pelagonia (Bitola) and Prilep, and Kamytzes goes over the Tempe pass into Thessaly (Choniates p. 293).Depends on: Kamytzes released alive; the emperor still refusing to repay the ransom or restore his property; Chrysos willing to break the 1197-1198 peace. Stopped by: The emperor repaying Chrysos or restoring Kamytzes; Kamytzes dying in captivity; Chrysos choosing the emperor's favour.
Places of note
- Kassandreia: Fort at the isthmus of Kassandra
Where the sources disagree
Evidence: No governor is named; the district's extent follows the old theme. The Partitio of 1204 leaves out Macedonia between the Maritsa and the Vardar because it went to Boniface, so it gives no check here.
On the map: A modern-unit approximation of the district; its northern edge toward Chrysos and toward Serres is not pinned.
