City commune · Northern Italy · as at first light, 1 January 1200

Commune of Treviso

Treviso is the most aggressive commune of the March.

Since the Peace of Constance it has pushed its rule over the bishops' counties north and east of it (Ceneda, Belluno and Feltre) and over the lords between the Piave and the Livenza (the da Camino, the da Prata), at the cost of wars with the patriarch of Aquileia, with the bishops and with Padua. In 1197 its soldiers killed the bishop of Belluno, and it was laid under interdict. In 1198-99, with Verona and Vicenza, it won its war: Ceneda surrendered on 15 June 1199 and the da Prata became its citizens and vassals that year.

On 1 January 1200 peace with the bishop of Feltre and Belluno is a month away and the quarrel with the patriarch is heading to arbitration at Verona. It has just built Castelfranco as a fortified new town on the Paduan border.

Overlord

The Empire in law (Peace of Constance, 1183)

What the realm holds

  • The city on the Sile and its suburbs
  • The plain to the Muson and Castelfranco (new town, about 1195-99), Noale and Mestre
  • The Montello and the hills from Asolo to Valdobbiadene
  • Conegliano and Ceneda (citizenship oath of 4 April 1184; Ceneda surrendered 15 June 1199)
  • Oderzo and the plain between the Piave and the Livenza; Brugnera, ceded by the da Prata in 1199
  • The castle of Zumelle (Mel) in the Piave valley, bought from the da Camino in 1188, destroyed by the bishop of Belluno in 1196 and rebuilt by Treviso after 1197
  • Overlordship of the da Camino (citizens 1183 and 1199) and of the Collalto counts

How it was acquired

Podesta beside the consuls from 1176; the Peace of Constance (1183) brought regalia; then the subjection of Ceneda, Conegliano, the bishops' lands and the da Camino and da Prata (it.wikipedia Storia di Treviso; DBI Prata).

Allies and rivals

Allied with Verona and Vicenza (1198 campaign) and bound to Venice by treaty (1192) and an agreement on legal procedure (1198). Enemies: the patriarch of Aquileia (war since 1183 under Godfrey, renewed in 1190 and 1198), the bishop of Feltre and Belluno (war of 1196-97), and in the 1190s Padua, which backed the patriarch. Ezzelino II is a citizen and was podesta in 1190-92.

The realm that morning

The podesta for 1200 is Pietro di Remengarda (Treccani), part of the exchange of podesta among the factions of Verona, Ferrara and Treviso; whether he or the 1199 officer held office on 1 January is not pinned (in 1190-92 Treviso's year of office ran from July). The war with the patriarch is not settled: in June 1199 Gherardo da Camposampiero swore to defend the Livenza towns against him; the parties will accept Verona's arbitration in March 1200. The quarrel with the bishop of Feltre and Belluno (Drudo da Camino held both sees from 1197 but died in 1199 or before early February 1200, so the see may be vacant that morning) ends in a concord on 2 February 1200.

The interdict Celestine III laid on Treviso for the killing of Bishop Gerardo de' Taccoli in 1197: whether it was still in force on 1 January 1200 is not pinned. Bishop of Treviso: a Church map record.

Wealth

The Sile river port and the road to the lagoon at Mestre, grain and wine of the plain, timber and iron from the Piave valley, tolls on the Piave and the Livenza crossings, the market of Treviso.

Military

City militia, the knights of the citizen lords (da Camino, Collalto, Camposampiero), hired companies (Vicentine troops under Valperto da Onigo in 1196-97). Castles at Castelfranco, Zumelle, Conegliano, Oderzo and Brugnera. No figures.

Threats

  • The patriarch of Aquileia and his Friulian vassals across the Livenza
  • The bishop of Feltre and Belluno and the papal interdict
  • Padua on the Muson
  • The da Camino and da Prata, vassals by force

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. 2 February 1200Concord between the commune of Treviso and the bishop of Feltre and Belluno.Depends on: Both sides keeping to the negotiation already in hand. Stopped by: A new raid in the Piave valley or a papal refusal.
  2. 29 March 1200Treviso's men pledge to accept Salinguerra's arbitration in the quarrel with the patriarch.Depends on: The patriarch's consent. Stopped by: Fighting on the Livenza.
  3. 26 May 1200The sentence is pronounced in Verona and sworn to by Treviso's men.Depends on: As above. Stopped by: As above.

Later, on the likely course

  1. 1201The patriarch is defeated near the Tagliamento by a league and must seek Venice's alliance (en.wikipedia, Pellegrino II) [thin].Depends on: The 1200 sentence failing to hold. Stopped by: The sentence holding.

Places of note

  • Castle of Zumelle: Treviso's castle in the Piave valley
  • Castelfranco: New fortified town on the Paduan border
  • Brugnera: Ceded by the da Prata in 1199

Where the sources disagree

  • The da Prata's citizenship pact with Treviso is dated 17 September 1199 in the DBI life of Guecello di Prata but 17-18 June 1199 in the DBI life of Gherardo da Camposampiero (who witnessed it).

Evidence: The 1196-1200 wars and settlements are well pinned by the Treccani lives (Prata, Camposampiero, Ezzelino II) and it.wikipedia (Gerardo de' Taccoli); the podesta that morning is not.

On the map: Mestre and the mainland behind Venice were Treviso's in 1200 but lie inside the modern comune of Venezia, drawn as Venice. The Livenza line between Treviso and the patriarch is rough; Sacile was the patriarch's. The da Camino lands (da Camino) lie inside this contado.
