Governor of Nikopolis

The old province (thema) of Nikopolis, named after the ruined Roman city at the mouth of the Ambracian Gulf, covers southern Epirus, Acarnania and Aetolia down to the Gulf of Corinth.

Naupaktos was its capital from the 880s and remains the metropolitan see; by 1198 the trading town of Arta seems to have become the governor's seat. That year's chrysobull shows the province broken up into estates (episkepseis) belonging to churches, monasteries and private holders, and the 1204 partition lists 'Nicopolla, cum pertinentia de Arta, de Achello, de Anatolico, de Lesianis'. The holders of these estates are not named.

The governor that winter may be Senachereim, whom Alexios III appointed at an unknown date.

Who he is

Name
Senachereim? (not pinned)
Title
Imperial governor (doux) of the province (thema) of Nikopolis
Since
Appointed by Alexios III (date not pinned)
Born
Not pinned
Family
Married to a Melissene, first cousin of Michael Komnenos Doukas's first wife (Life of St Theodora of Arta)
Confidence
low

The late 13th-century Life of St Theodora of Arta, often thought unreliable, says Alexios III made Senachereim governor of Nikopolis and that the local people killed him before Michael Komnenos Doukas arrived (1204-1205); Michael then married his widow and succeeded him. Villehardouin partly confirms this: Michael married the daughter of a great local man. Whether Senachereim already held the post on 1 January 1200 is not known.

Overlord

The emperor Alexios III Angelos.

What it holds

  • Arta and the plain of the Arachthos and Louros, with the ruins of Nikopolis and the fortress-see of Rogoi (Arta)
  • The estate (episkepsis) of Arta
  • Acarnania with Vonitsa (Vonitsa) and the estates of Achelous and Anatolikon (Anatolikon)
  • Aetolia with Naupaktos, the metropolitan see (Naupaktos)
  • The estate of Lesiana (place not pinned)
  • Lefkada (never taken by the Normans in 1185; whether it answered to Nikopolis or went with Corfu, the remnant of the old island theme of Kephallenia, as in the 1204 list 'Leukas et Coripho', is not pinned)

How it was acquired

Imperial throughout the 12th century; Bohemond besieged Arta without success in 1082.

Allies and rivals

The great local families (the Melissenoi by marriage, on the Life of St Theodora; no estate of theirs is located); the metropolitan of Naupaktos; the Venetian traders at Arta and Vonitsa. Rival across the water: the count of Kefalonia.

How things stand that morning

Byzantine. A governor appointed by Alexios III holds the province from Arta, possibly Senachereim (low confidence); the episkepseis are in the hands of churches, monasteries and private holders whose names are not recorded. Across the borders: Vagenetia (doux of Dyrrachion) north of the Acheron, the province of Ioannina to the north, Thessaly (mac) beyond the Pindus, Hellas (pel) beyond the Mornos, Patras and the Peloponnese (pel) across the Gulf of Corinth, the count of Kefalonia's islands to the south-west.

Wealth

The plains of Arta and the Achelous, the lagoons and fisheries of Mesolongi and Anatolikon, the harbours of the Ambracian Gulf and of Naupaktos, the Venetian trade (Arta had links with Venice in the Komnenian period).

Military

Walled Naupaktos and Vonitsa; the fortress of Rogoi; Arta's castle is not yet built (Michael I builds it after 1205). No numbers.

Threats

  • The count of Kefalonia and the corsairs of the Ionian Sea
  • The breakdown of imperial authority in the provinces

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.

  1. 1204-1205 (beyond 1200)The local people kill the governor Senachereim; Michael Komnenos Doukas, Alexios III's cousin, marries his widow and takes over the province from Arta, the start of the later state of Epirus.Depends on: The fall of Constantinople (1204) and the collapse of imperial authority Stopped by: A surviving empire, or Senachereim keeping his people's loyalty

Places of note

  • Nikopolis (ruins): The Roman city that gave the province its name; long abandoned

Where the sources disagree

  • The only name for this governorship under Alexios III comes from a late hagiography; the date of the appointment is unknown, so the holder on 1 January 1200 is not pinned.

Evidence: The province's make-up is known from the 1198 chrysobull and the 1204 partition; its governor rests on the Life of St Theodora of Arta.

On the map: Rough outlines; the inner bounds of the estates (episkepseis) are unknown, and the eastern edge against Thessaly and Hellas is guessed along the Pindus and the Mornos.
