The capital of the empire and the greatest city of Christendom, on its triangle between the Golden Horn, the Bosporus and the Sea of Marmara, behind the land walls of Theodosius.
The emperor lives at Blachernae in the north-west corner; the Great Palace by the Hippodrome is used for ceremonies and races. The eparch of the city governs its streets, prisons, markets and guilds; the patriarch John X Kamateros sits at Hagia Sophia. The Golden Horn shore is lined with the walled quarters of the Venetians, Amalfitans, Pisans and Genoese; across the Horn at Pera live the Jews; Muslim merchants have their own mosque (the Mitaton).
The suburbs reach along the Marmara past the Golden Gate, up the Golden Horn past Blachernae and along the European shore of the Bosporus (the Stenon); the Partitio of 1204 lists them as the districts of the Golden Gate, of Blachernae and of the western Stenon. That winter the city is quiet but restless: the keeper of the prisons, John Lagos, is selling releases and pocketing alms, and the emperor's tax men covet the fortunes of the money-changers.

How things stand that morning
The emperor's city, quiet on 1 January. The empress, the court, the patriarch and the Italian communities are all in residence; the prisoners Isaac II and his son are kept by the Golden Horn.
Charter
No charter. The guilds (systemata) are regulated by the Book of the Eparch; the Italian quarters hold their ground and privileges by imperial chrysobull.
Council
No town council. The senate of title-holders, the patriarch and his synod, the guild masters and the crowd (demos), which acclaims emperors and riots (1182, 1200).
Communities
Greeks; the Venetians, Pisans, Genoese and Amalfitans in their quarters (Venetians, Pisans, Genoese, Amalfitans); Jews (Rabbanites and Karaites) at Pera; Muslim merchants round the Mitaton mosque by the Golden Horn; Armenians, Georgians and Rus'; the English and Scandinavian Varangians.
Fairs and markets
Daily markets along the Mese and its forums and at the landings of the Golden Horn; no fair dates pinned.
Militia
No militia; the Varangian guard, the palace guards and hired troops. The crowd arms itself in a riot.
Walls and castle
The double land wall of Theodosius II with its moat, from the Golden Gate to Blachernae; Manuel I's wall round the Blachernae palace; the sea walls along the Marmara and the Golden Horn; the chain across the Golden Horn from the city to the tower of Galata at Pera. Palaces: Blachernae and the Great Palace.
Trade and crafts
Silk weaving and dyeing (the palace workshops and the private silk guilds), goldsmiths and jewellers, perfumers, candle-makers, money-changers and bankers (the money-changer Kalomodios is the richest man of the city), the grain, fish and wine trades, the carrying trade of the Black Sea and the Levant through the Italian quarters, Rus' traders. The tolls (kommerkion) of the harbours and of the straits at Hieron and Abydos (the last two in Asia) feed the treasury.
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.
- early February 1200Riot against John Lagos, keeper of the prisons; the despotes Alexios Palaiologos brings troops in to restore order.Depends on: Lagos still in post. Stopped by: his removal.
- 1200 or 1201 (not pinned)The emperor's financial officers arrest the rich money-changer Kalomodios; the merchants occupy Hagia Sophia and threaten to throw the patriarch John Kamateros from the altar unless he wins his release, which he does.Depends on: the treasury's hunger for cash. Stopped by: a full treasury.
- 31 July 1201 (or 1200)John Komnenos the Fat is crowned in Hagia Sophia by his partisans and seizes the Great Palace; he is cut down the same day.Depends on: the plotters' secrecy. Stopped by: an alert guard.
Places of note
- Hagia Sophia, the patriarch's church: Seat of the patriarch John X Kamateros.
- Church of the Holy Apostles: Imperial burial church whose tombs were stripped for the German tribute in 1197.
- Pantokrator monastery: Komnenian foundation and mausoleum with its hospital; great estates in Thrace.
- Golden Gate: The ceremonial gate at the Marmara end of the land walls.
- Tower of Galata at Pera: The tower that holds the chain across the Golden Horn (approximate).
- The Mitaton mosque: The Muslim merchants' mosque by the Golden Horn (position approximate).
Where the sources disagree
Evidence: The city is richly described; the eparch and the officers of the quarters in 1200 are not pinned, and no source gives a population figure for 1200 that historians trust.
On the map: The tierra covers the city, Pera and the European suburbs (the Golden Gate, Blachernae and Stenon districts of 1204) out to the Kucukcekmece lake and the Black Sea mouth of the Bosporus; the Asian shore (Chrysopolis, Chalcedon) is drawn by the Anatolia sheet.
