Venice on the morning of 1 January 1200 is a sea republic of merchants, shipowners and salt-makers spread over the islands of the lagoon, ruled by a very old and blind doge, Enrico Dandolo, under a sworn oath and a set of councils that bind him.
It holds the lagoon duchy from Grado in the east to Cavarzere and Loreo in the south-west, a chain of rights and quarters in Constantinople, Acre and Tyre, the oaths of the Istrian coast towns and some of the Kvarner islands. It has lost Zara to the king of Hungary and wants it back. On the mainland it holds almost nothing and lives by treaties with the river communes.
The great event of its next years, the crusade, has not reached it yet: Theobald of Champagne was chosen leader at Ecry on 28 November 1199, but the crusaders' envoys will not come to Venice until early 1201.

Overlord
None. Venice acknowledges no lord: the Empire's kingdom of Italy does not reach the lagoon, and the old Byzantine tie is only a matter of titles and privileges.
What the realm holds
- The lagoon duchy (dogado): Grado, Caorle, Cittanova (Eraclea), Equilo (Jesolo), Torcello with Burano, Mazzorbo and Ammiana, Murano, the Rialto islands (the city), the Lido and Malamocco, Chioggia, Brondolo and Fossone, Cavarzere on the Adige and Loreo near the Po mouths
- The salt pans of Chioggia and the lagoon
- Quarter, churches, quays and trading rights in Constantinople (chrysobull of Alexios III Angelos, November 1198, renewing the privileges of 1082)
- A third of Tyre and a quarter in Acre in the kingdom of Jerusalem (the Pactum Warmundi of 1123-24)
- The oaths of fidelity of the Istrian coast towns (sworn 1145-1150: Capodistria, Isola, Pirano, Parenzo, Rovigno, Umago, Cittanova, Pola) (fri records the towns)
- Ossero and Cherso and Arbe in the Kvarner, and the Frankopan counts of Veglia as Venetian vassals (fri records the islands)
How it was acquired
The duchy is the old Byzantine province of the lagoons, independent in practice since the ninth century; the bounds from Grado to Cavarzere and Loreo are those of the Pactum Lotharii (840). The commune (Commune Veneciarum) and its councils grew under Doge Sebastiano Ziani (1172-78). Dandolo was chosen in June 1192 as an old, blind and respected compromise between the great families and the merchant body (Treccani).
Allies and rivals
Treaties with Verona and Treviso (1192), with Pisa (1196) (Treccani), an agreement with Treviso on legal procedure (1198) (it.wikipedia, Storia di Treviso). Pisa is the rival in the Adriatic: it backed the rebels of Zara (1188) and seized Pola in 1195 until the Venetians drove it out (it.wikipedia). Hungary under King Emeric holds Zara. The patriarch of Aquileia is a neighbour and rival on the Friulian shore (a pact follows in 1200, likely course).
The pope wants Venetian ships for the crusade.
The realm that morning
Dandolo rules with his councils from the ducal palace at San Marco. The Great Council (Maggior Consiglio) and the Minor Council of the doge's councillors govern day to day; a council of Forty (Quarantia) existed since Ziani's time; the people's assembly (concio, arengo) in San Marco still approves great decisions, as it will approve the crusade treaty in 1201. The doge's oath (promissione) of 1192 is the oldest that survives: he swore to rule by the laws, to act with the consent of the Minor Council and the majority of the Great Council, not to meddle in choosing the patriarch of Grado or the lagoon bishops, and not to deal privately with foreign powers (Treccani).
The patriarch of Grado, the Venetian church's own head, is Giovanni Signolo according to the campaign notes [thin]; he lives in Venice at San Silvestro, and the lagoon bishops of Castello, Torcello, Chioggia, Caorle, Equilo and Cittanova are under him (Church map records). The papal legate Soffredo, cardinal of S. Prassede, was sent to Venice in 1198 to win it for the crusade; whether he is still in the city that morning is not pinned (campaign notes).
On the mainland Venice governs only the duchy's own strips of shore; Mestre and the land behind the lagoon are Treviso's, the Brenta mouths and Oriago Padua's.
Wealth
Shipping and long-distance trade with Constantinople, the Levant and Egypt (Innocent III let the Venetians trade in goods other than arms, iron and timber with Egypt in 1198 [fair]), salt from Chioggia and the lagoon sold up the rivers, fish, glass, the Rialto market, and the tolls on goods entering the lagoon. Money: the Venetian penny (denaro); the silver grosso is dated to about 1193-94 by most accounts, but some numismatists put its first striking in 1201-02 to pay the crusaders (not pinned).
Military
The fleet is raised from the parishes and the shipowners and commanded by the doge or his kin; Venice fought Pisa in the Adriatic and the rebels of Zara in the 1180s and 1190s, and in 1193 Dandolo recovered Pago and the Kvarner islands but not Zara (it.wikipedia). No reliable figure for ships or men in 1199-1200.
Threats
- Zara in Hungarian hands and Hungarian ambitions on the Dalmatian coast
- Pisan ships and Pisan friends in the Adriatic
- The patriarch of Aquileia and the Friulian lords on the eastern shore
- The mainland communes (Padua, Treviso) if they choke the river trade or the salt
- The crusade, which the pope wants Venice to carry and which will cost and pay enormously
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
- 1200 (day not pinned)A pact between Venice and Patriarch Pellegrino II of Aquileia (Treccani lists a treaty with the patriarch in 1200).Depends on: The patriarch needing peace on his Venetian flank while his war with Treviso goes to arbitration in spring 1200. Stopped by: A Venetian quarrel with the patriarch over the Friulian shore or the Istrian towns.
Later, on the likely course
- Early 1201Six envoys of the crusade barons (Geoffrey of Villehardouin among them) reach Venice and ask for ships; the treaty is sealed in April 1201.Depends on: The crusade going ahead under Theobald of Champagne (elected at Ecry on 28 November 1199) and choosing the sea route. Stopped by: The crusade collapsing, or the barons choosing Genoa or Pisa.
- 1202Dandolo takes the cross; the crusade fleet sails against Zara (November 1202).Depends on: The crusaders failing to pay the sum agreed in 1201. Stopped by: Full payment, or a Venetian settlement with Hungary over Zara.
Places of note
- Ducal palace and San Marco: Seat of the doge and councils
- Chioggia salt works: Second town of the duchy
Where the sources disagree
- Election date: it.wikipedia gives 21 June 1192; some lists give 1 June 1192. Treccani places the election after Orio Mastropiero's death on 14 June 1192, which fits 21 June.
- campaign notes name the patriarch of Grado as Giovanni Signolo [thin]; nothing found against it. Part 11 ruling 11 says the name is the campaign's to fix.
Evidence: Dandolo's life, oath and treaties are well documented (Treccani DBI); the exact councils' membership in 1200 and the grosso's date are not.
On the map: The duchy was islands, littoral strips and lagoon; the modern comuni used here take in mainland ground that was not Venetian in 1200, above all Mestre and Marghera inside the comune of Venezia (Treviso's in 1200) and the inland parts of Jesolo, Eraclea and Caorle. The Istrian and Kvarner rights are in fri's records and are not drawn here.
