The War of Ferrara (also known as the Salt War, Italian: Guerra del Sale) was fought in 1482–1484 between Ercole I d'Este, Duke of Ferrara, and the forces mustered by Ercole's personal nemesis, Pope Sixtus IV and his Venetian allies. Hostilities ended with the Treaty of Bagnolo, signed on 7 August 1484.
