Trebizond

Trebizond stands on a flat-topped spur between two ravines above its harbour, with the citadel at the upper end and the walled middle and lower towns below.

It is the head of the old theme of Chaldia, with the cathedral of the Panagia Chrysokephalos and the monastery of its patron, St Eugenios, and it is the sea end of the road over the Zigana pass to Paipert (Bayburt) and Erzurum. The Gabras family once ruled it as near-independent dukes, the last of them, Constantine Gabras, until John II's expedition of 1139; since then imperial officers have governed it, but no governor is named for 1 January 1200. Its neighbours are the Laz and the kingdom of Georgia to the east, now at its height under Queen Tamar, and the Turks beyond the mountains to the south.

In April 1204 Alexios and David Komnenos, grandsons of Andronikos I and kinsmen of Tamar, will seize it with Georgian troops (later).

low

No governor is named for 1199-1200. A Nikephoros Palaiologos governed Trebizond under Manuel I (Choniates), which is no evidence for 1200.

Lord in 1200

Alexios III, through his governor of Trebizond (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; far from the capital and reached chiefly by sea.

Threats

  • Georgian ambitions (the expedition of April 1204)
  • Turks of the interior (the Saltukids of Erzurum and the Seljuks)

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; Laz; Armenians; Georgians (Georgian settlement in the region grows under Tamar).

Militia

Townsmen man the walls in a siege; the field troops are the governor's and the emperor's.

Walls and castle

The citadel and the walled upper and middle towns on the spur, closed by the two ravines (late Roman, rebuilt under Justinian and later).

Trade and crafts

Trade with Georgia and with the Saltukid and Seljuk interior over the Zigana pass; sea trade with Constantinople and the Crimea; wine, fruit and timber of the coast. The great Tabriz caravan trade comes after the Mongol conquests (later).

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. April 1204 (later)Alexios and David Komnenos take Trebizond with troops given by Queen Tamar; Alexios is proclaimed emperor, the beginning of the empire of Trebizond.Depends on: Georgian backing and the capital's paralysis in 1203-1204. Stopped by: a strong governor and a working government in Constantinople.

Places of note

  • Panagia Chrysokephalos, the cathedral: The cathedral church inside the walls.
  • Sumela monastery: The monastery of the Virgin in the Matzouka valley.

Where the sources disagree

Evidence: The town and the 1204 seizure are well known; no officer of the 1190s is named.

On the map: Town and near land; Chaldia is drawn by Chaldia.
