Vol. 4: A 1209 usque ad 1300

King Otto IV holds an imperial diet in Augsburg where he deals, among many other things, with the fate of the condemned murderers of King Philip and the Margraviate of Istria (notices from contemporary narrative accounts, Otto of St. Blasien’s and Conrad of Scheyern’s chronicles).

Otto IV, King of the Romans, confirms the rights of the Patriarchate of Aquileia over the Duchy of Friuli, including the incomes from the administration of criminal justice, and all documented agreements made between Patriarch Peregrine I and Count Maynard I of Gorizia as well as Patriarch Ulrich II and Count Engelbert II of Gorizia regarding advocacy and other matters.

Otto announces to all the subjects of the Empire in Italy that he has appointed Patriarch Wolfger of Aquileia imperial legate for Lombardy, Tuscia, the Duchy of Spoleto and the Marches of Ancona and Romaniola, commanding them to receive him honorably and to recognize his decisions in imperial affairs.

King Otto IV invests Patriarch Wolfger with imperial regalian rights and attests that his successors do not need to journey to German lands to receive the regalian investiture because the patriarchs of Aquileia are one of the Italian ecclesiastical princes.

On the behest of Wolfger, the patriarch of Aquileia, and other princes gathered at the Diet of Augsburg, King Otto IV accepts the resignation of the Margraviate of Istria from Duke Ludwig of Bavaria and donates the same Margraviate to Patriarch Wolfger and the Church of Aquileia.

Henry of Andechs-Merania, the margrave of Istria, donates a property of his to the monastery of Saint Lawrence in Wilten (Innsbruck), for the salvation of his soul and the souls of his parents.

Henry of Andechs-Merania, the margrave of Istria, donates properties to the monastery of Saint Mary and Saint Hermagoras in Obernbug for the salvation of his soul.

Berthold V of Andechs, patriarch of Aquileia, promises to the envoys of Doge Pietro Ziani and the Commune of Venice the security of Venetians within the boundaries of his temporal dominion; assures the recompense in case a Venetian ends up being robbed within his territories; promises to inform the Venetians in case of hostilities planned against them by the Empire; and he commits himself to amend the agreement, if necessary, in accordance with the Venetian doge.

Berthold V of Andechs, patriarch of Aquileia, and Count Maynard II of Gorizia, his advocate, promise to Doge Pietro Ziani and to the Commune of Venice the safety of Venetians living and operating within the confines of the temporal dominion of the Aquileian Church; promise to reimburse any Venetian if they end up robbed in the Patriarchate; to inform the Venetians if they find out that the Empire is planning any hostilities against them; and define the competences of the vicedominus of Aquileia; Venetians are promised exemptions from customs duties throughout the secular dominion of the Aquileian patriarchs and privileged judicial status.

Nicolò Cocco, podestà of Koper, in agreement with the Major and Minor civic councils and by the authority of the entire Commune, appoints Emery Spandinuces as authorized representative of the Commune in the dispute between the Commune of Koper and the Monastery of St. Mary of Aquileia; Emery is authorized to elect arbitrators and mediators, and to give and receive security for the arbitration settlement agreed in writing between the podestà of Koper and the abbess of St. Mary’s monastery.

The Bishopric of Poreč, represented by Bishop Adalpero and the local Chapter, and the Commune of Poreč, represented by the gastald, the meriga, and three consuls, conjointly elect eight honorable citizens of Poreč to define the borders of the city’s district from which the bishops had the right to quartese, that is, a quarter of the tithe.

In the name of Berthold V, the patriarch of Aquileia, John of Portis swears to uphold the peace and the treaties signed between the Aquileian patriarchs and the Commune of Venice.

Answering the pleas of Aquileian Patriarch Berthold, Emperor Frederick II proclaims and ratifies the verdict of the imperial princes gathered at the Diet of Ravenna, confirming the secular rights and prerogatives of Aquileian patriarchs and forbidding the election of rectors and the exercise of regalian rights to the subjected urban communities, especially to the Istrian cities of Koper, Poreč, and Pula.

In the name of Patriarch-margrave Berthold V of Andechs, John de Riva, the general gastald in Istria, orders a Nicholas de Roço of Poreč and all his supporters to present themselves in front of the patriarch in Friuli and to respond to allegations raised against them by a Marino de Mengoso of Poreč and his supporters.

The representatives of the Commune of Trieste pledge fealty to Venice, promising to observe the pacts agreed by the two polities regarding the rights, status, and mercantile freedoms of the Venetians in Trieste (the edition includes the appended and originally undated pact between Venice and Trieste mediated by the prior of Santa Maria dei Crociferi and Pietro Zeno, and the oaths of consuls of Trieste and Venetian advocates serving in Trieste).

Answering the pleas of Aquileian Patriarch Berthold V, Emperor Frederick II decrees that throughout Friuli and Istria criminal justice administration and everything else pertaining to corporal punishments and coercion (merum et mixtum imperium) resides exclusively with the patriarch of Aquileia, threatening to deprive of their fiefs anyone who would dare to administer criminal justice on patriarchal territories.

The Venetian navy sets out to engage the inimical fleet of Emperor Frederick II and the Pisans, but the Commune of Pula refuses to arm a galley for the military undertaking, provoking Venice to attack the city and raze its walls; on the way back, in October of the same year, the Venetians attack the rebelling Pula once again (narrative account from Andrea Dandolo’s Chronica per extensum descripta).

Nascingwera, the regalian podestà of Pula, and the communal council of the city elect and constitute priest Hugh and subdeacon John de Spago as the official representatives of the Commune of Pula, delegated to sign a new peace treaty with the doge and the Commune of Venice following their recent inimicalities.

The communes of Venice and Pula sign a new peace treaty and agree on ten articles regulating their future relations.

The people of Pula, united in the general assembly, formally ratify the treaty signed between the representatives of their commune and Venice on January 21, 1243 (doc. 1243_PP).
