Hostilities ended with the Treaty of Bagnolo, signed on 7 August 1484. Diplomatic backgroundThe failure of the Pazzi Conspiracy against Florence in 1480 and unexpected peace as a result of Lorenzo de' Medici's daring personal diplomacy with Ferdinand I of Naples, the Pope's erstwhile champion, was a source of discontent among the Venetians and Pope Sixtus IV alike. Venice had ended its long conflict with the Ottoman Turks in 1479, with the Treaty of Constantinople, and was freed to turn its complete attention to its role in its terra firma (main land) and generally to the peninsula of Italy. In addition to the usual minor friction over strongholds along the borders, there was a contest over the commerce in salt, which was reserved to Venice by a commercial pact. Nevertheless, Ferrara, which was ruled by Ercole I d'Este, had begun to take control over the saltworks at Comacchio. This appeared to be a threat to mainland interests of the Serenissima. Venice was supported by Girolamo Riario, lord of Imola and Forlì, – the nephew of Pope Sixtus – who had taken possession of the strategic stronghold of Forlì in September 1480, with quick papal confirmation, and who now looked towards Ferrara in extending Della Rovere territory. The immediate casus belli at the beginning of 1482, as usual was a minor infraction of prerogatives: Venice maintained a representative in Ferrara with the high title of visdominio, under whose care was the Venetian community in Este lands. In 1481, overreaching his mandate with the arrest of a priest for debt, the visdominio was excommunicated by the vicar of the bishop of Ferrara, and forced out of the city. On this excuse, war was declared.[1] Allied with Venice, besides the papal troops and Riario, were contingents supplied by the Republic of Genoa and William VIII, Marquis of Montferrat.[2] Taking Ferrara's side, loosely under the command of Federico da Montefeltro, duke of Urbino, were troops of Ercole's father-in-law Ferdinand of Naples, under his son Alfonso of Calabria, who invaded the Papal States from the south, as well as troops sent by Ludovico il Moro of Milan and by the lords of two cities threatened by the mainland power of Venice, Federico I Gonzaga of Mantua and Giovanni II Bentivoglio of Bologna. HistoryVenetian troops led by the condottiero Roberto Sanseverino[3] attacked Ferrarese territory from the north, brutally sacking Adria, quickly overrunning Comacchio, attacking Argenta at the edge of the saltmarshes and besieging Ficarolo in May (capitulated 29 June) and Rovigo (capitulated 17 August). Venetian forces crossed the Po River and in November 1482 stood before the walls of Ferrara and laid strict siege to the city. Sixtus appears to have had a change of heart at the season's advances, which now threatened to put Venice in an uncomfortably strong position in mainland northern Italy. In the Papal States, the Colonna family took advantage of disorder, and fought pitched battles against their Della Rovere enemies. The main encounter, however, was the pitched Battle of Campomorto near Velletri, 21 August 1482, in which the Neapolitan troops were soundly defeated by Roberto Malatesta and the duke of Calabria was barely rescued by a contingent of his Turkish soldiers. Some Orsini castles also fell into papal hands, but where battle failed malaria succeeded : Roberto Malatesta's death in Rome on 10 September largely unraveled Papal successes in the Lazio. Sixtus made a separate peace with Naples in a truce of 28 November and a peace treaty was signed on 12 December. His entreaties with Venice to cease hostilities were vigorously rebuffed, with threats of excommunication countered by the withdrawal of the Venetian ambassador, followed by Sixtus' interdict of Venice in May 1483. Now Sixtus granted free passage to Alfonso and his troops to go to defend Ferrara against the pope's recent allies, aided by papal troops under Virginio Orsini. A contingent of Florentine troops arrived also, and the fortunes of Este began to look much better. In a diversionary maneuver, Venice sent Roberto Sanseverino to attack the Duchy of Milan under the pretext of supporting the rights of the Visconti heir, but the diversion was further diverted when Robert had to counter Alfonso, who was sacking Milanese territories. The war began to lose momentum. Treaty of BagnoloThe war came to a conclusion with the Treaty of Bagnolo, signed on 7 August 1484. Ercole ceded the territory of Rovigo in the Polesine, lost at an early stage of the fighting, and the Venetian forces that were occupying Ferrara-owned territory withdrew. Ercole had successfully avoided the absorption of Ferrara, seat of the Este, into the Papal States. Sixtus was rendered more eager to sue for peace by the series of victories by Venetian forces, who seized the opportunity to forward their territorial ambitions and had been hasty to declare war on Ferrara on a minor pretext. Florence, Naples, Mantua, Milan, and Bologna stood by Ferrara. While the papal forces were holding in check the Neapolitans who sought to move north to aid Ferrara, and with the Roman Campagna being harassed by the Colonna, and Milan engaged in combat with Genoa, the Venetians had besieged Ferrara into starvation. With the Venetians ready to take over Ferrara, the Pope, fearing his erstwhile allies, suddenly changed sides: he made a treaty with Naples, and permitted the Neapolitan army to pass through his territories, giving them the chance to convey supplies to Ferrara and neutralize the siege. At the same time the Pope excommunicated the Venetians, and now urged all Italy to make war upon them. The Peace of Bagnolo checked Venetian expansion in the terra firma, ceding to it the town of Rovigo and a broad swath of the fertile delta of the Po. This acquisition agreed upon at Bagnolo marked the high-point of Venetian territory; never again would Venice control so large a territory nor have so much influence as it did in the last half of the 15th century. Nevertheless, Sixtus was not pleased with the terms reached without consulting him: {{bquote|The news of it literally killed Sixtus. When the ambassadors declared to him the terms of the treaty he was thrown into a violent rage, and declared the peace to be at once shameful and humiliating. The gout from which he suffered reached his heart, and on the following day— 12 August 1484— he died.}}The war was the subject of an anonymous poem entitled La guerra di Ferrara[4] See also
Notes1. ^Ercole d'Este was married to Eleonora, daughter of Ferdinand of Naples. The Venetians cannot have forgotten how recently Ferrara and Naples had aligned with Florence and Milan against Venice. Riario stood to gain Ferrara, and Venice would be awarded Reggio and Modena. 2. ^Pier Maria II de' Rossi, count of San Secondo, also contributed a contingent. 3. ^Who had very recently squabbled with Ludovico il Moro. 4. ^on-line text Further reading
