Larissa and the plain

Thessaly is not one block of land under one man.

From the early 11th century it was counted with the theme of Thessalonica rather than with Hellas, and by the 12th century it had broken into small fiscal districts. The Partitio of 1204, drawn from Byzantine registers, lists the district (horion) of Larissa, the province of Vlachia, the empress's estates (Pharsalos, Domokos, the two Halmyroi, Demetrias and others), Neopatras, Velechativa, Platamon, Petrion and others. This record stands for the officer at Larissa and the units with no other named holder: the horion of Larissa and the western plain with Trikala and Stagoi.

The empress's estates, Vlachia and Neopatras have their own records.

Who he is

Title
Governor at Larissa (title not pinned: doux, praktor or kephale)
Since
not pinned
Confidence
low

John Petraliphas, sebastokrator, was sent by Isaac II to govern 'Thessaly and Macedonia' (Life of St Theodora of Arta). Isaac reigned 1185-1195 and again 1203-1204, and Petraliphas joined the coup of 1195 for Alexios III, so his governorship may fall before 1195 or after 1203; whether he held it on 1 January 1200 is not pinned. The joint title fits the older arrangement: from the early 11th century Thessaly was detached from Hellas and joined to the theme of Thessalonica, and over the 12th century smaller fiscal districts (horia) took the place of the old themes, one of them based on Larissa.

Overlord

Alexios III

What it holds

  • Larissa and its horion: the eastern plain along the Pineios
  • Trikala and the western plain (attachment not pinned)
  • Stagoi (Kalambaka) and the Meteora hermitages
  • Elassona and the road to Servia
  • the Tempe pass toward Platamon

How it was acquired

Office in the emperor's gift.

Allies and rivals

The empress's stewards on her estates; the Vlach herdsmen of the hills; the Italian merchants at Halmyros.

How things stand that morning

Byzantine; quiet that winter.

Wealth

The grain and livestock of the largest plain in the Greek lands; the Vlachs' flocks.

Military

The castles of Larissa, Trikala and the Tempe and Elassona passes. No numbers.

Threats

  • Kamytzes's invasion over Tempe (1201)
  • Vlach raiding from the hills, as Benjamin of Tudela describes in the 1160s

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.

In 1200

  1. 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.

Later, on the likely course

  1. Autumn 1201 into 1202Alexios III takes the field. He offers Chrysos his granddaughter Theodora (Ivanko's widow); Chrysos accepts and gives up Pelagonia and Prilep, keeping Prosek and its countryside. Kamytzes refuses a pardon brought by John Oinopolites, is beaten in Thessaly, wounded, and flees to Stanos, then probably to Bulgaria (Choniates pp. 293-294; Varzos).Depends on: The revolt of 1201 happening; Ivanko already dead, so that Theodora is free. Stopped by: A different outcome in the field, or Kaloyan intervening in force.

Where the sources disagree

Evidence: The Partitio (1204) for the units and Wikipedia's Hellas (theme) for the 11th-12th century arrangement; no governor named for 1200.

On the map: Several 1204 units are merged here; Velechativa, Petrion and Pazi/Radovisdion, whose sites are uncertain, are not drawn.
