The Guerre of Ferrare was held 1482 with 1484 and ended with the peace of Bagnolo, signed on August 7th, 1484. She opposed Hercules Ier d' Este, duke of Ferrare and her father-in-law Ferdinand Ier of Naples to Venice and the Papal States.
Diplomatic context
The unexpected peace which has occurred in 1480 following the diplomatic operations of
Laurent de Médicis towards the king
Ferdinand Ier of Naples, before very near to the pope, had been a source of dissatisfaction as well on the Venetian side as of that of the pope Sixte IV. Venice released from a long conflict with the
Ottoman Empire following the treated of Constantinople in 1479 could from now on defer its attention on the Italian peninsular policy.
The nephew of the pope,
Girolamo Riario, had taken possession of the strategic fortress of Forli in September 1480. In its desire to more increase the territorial influence of the family
Della Rovere, it lorgnait from now on towards the possessions of the duchy of Ferrare. At the beginning of 1482, it convainquit Venice to declare the war with Hercules Ier d' Este, duke of Ferrare. Venice was then in a phase of expansionism out of dry land. Beyond the usual conflicts on the possession of fortresses along the borders, the Sérénissime republic saw its terrestrial interests threatened by the Maison of Este which, with the contempt of trade agreements holding the trade of the salt in Venice, had started to produce salt with
Comacchio.
Venice counted among its allies, beyond the pontifical troops and of those of Girolamo Riario, lord of
Imola and Forli, the République of Genoa and the marquisat of Montferrat. The troops of Ferrare placed under the command of Federico da Montefeltro could count on the support of the troops of Ferdinand Ier of Naples, ordered by the son of this one, Alphonse of Calabria. Side of Ferrare were also engaged of the quotas provided by Ludovic the Moor, duke of Milan and by the lords of the two cities threatened by the expansionism Venetian:
Frederic Ier de Mantoue and Giovanni II
Bentivoglio of
Bologna.
Unfolding of the war
The Venetian troops led by the
Condottiere Roberto da Sanseverino attack the territories ferrarrais by North, putting at bag
Adria, taking the control of Comacchio quickly, attacker Argenta at the edge of the salt-water marshes and besieging
Ficarolo in May (capitulation on June 29th) and
Rovigo (capitulation on August 17th). The Venetian ones cross the
Po and put the seat in front of the walls of Ferrare in November 1482.
In the south, the Neapolitan troops, with the support of part of the Roman oligarchy pulled by the Colonna, invade the states of the church and besiege
Rome. However on August 21st, 1482, with the battle of Campo Morto, close to
Velletri, Roberto Malatesta demolishes the Neapolitan troops. Papal successes in the
Latium seriously were compromised by the death of Roberto Malatesta on September 10th, 1482. Sixth IV concludes a peace separated with the kingdom from Naples and its allies by signing a truce on November 28th and a peace treaty on December 12th, 1482.
