The Peace of Cremona ends the war between the Republic of Venice and the Duchy of Milan, after the victorious Venetian enterprise of military engineering of the Galeas per montes.

The Peace of Cremona was concluded on 20 November 1441 between the Republic of Venice and the Duchy of Milan, ending the fourth of the five campaigns in the long conflict between the two powers over mastery in northern Italy.

The Republic of Venice, officially the Most Serene Republic of Venice and traditionally known as La Serenissima, was a sovereign state and maritime republic with its capital in Venice. Founded, according to tradition, in 697 by Paolo Lucio Anafesto, over the course of its 1,100 years of history it established itself as one of the major European commercial and naval powers. Initially extended in the Dogado area, during its history it annexed a large part of Northeast Italy, Istria, Dalmatia, the coasts of present-day Montenegro and Albania as well as numerous islands in the Adriatic and eastern Ionian seas. At the height of its expansion, between the 13th and 16th centuries, it also governed Crete, Cyprus, the Peloponnese, a number of Greek islands, as well as several cities and ports in the eastern Mediterranean.

The Duchy of Milan was a state in Northern Italy, created in 1395 by Gian Galeazzo Visconti, then the lord of Milan, and a member of the important Visconti family, which had been ruling the city since 1277. At that time, it included twenty-six towns and the wide rural area of the middle Padan Plain east of the hills of Montferrat. During much of its existence, it was wedged between Savoy to the west, Republic of Venice to the east, the Swiss Confederacy to the north, and separated from the Mediterranean by the Republic of Genoa to the south. The duchy was at its largest at the beginning of the 15th century, at which time it included almost all of what is now Lombardy and parts of what are now Piedmont, Veneto, Tuscany, and Emilia-Romagna.

Galeas per montes is the name given to a feat of military engineering made between December 1438 and April 1439 by the Republic of Venice, when several Venetian ships, including galleys and frigates were transported from the Adriatic Sea to Lake Garda. The operation required towing the ships upstream on the river Adige until Rovereto, then transporting the fleet by land to Torbole, on the Northern shores of the lake. The second leg of the journey was the most remarkable achievement, requiring a land journey 20 km through the Loppio Lake and the narrow Passo San Giovanni.
