The Albanian–Venetian War of 1447–48 was waged between Venetian and Ottoman forces against the Albanians under George Kastrioti Skanderbeg. The war was the result of a dispute between the Republic and the Dukagjini family over the possession of the Dagnum fortress. Skanderbeg, then ally of the Dukagjini family, moved against several Venetian held towns along the Albanian coastline, in order to pressure the Venetians into restoring Dagnum. In response, the Republic sent a local force to relieve the besieged fortress of Dagnum, and urged the Ottoman Empire to send an expeditionary force into Albania. At that time the Ottomans were already besieging the fortress of Svetigrad, stretching Skanderbeg's efforts thin. However, the League of Lezhë defeated both the Venetian forces and the Ottoman expedition. The League won over the Venetian forces on 23 July 1448 at the gates of Scutari, and over the Ottomans three weeks later, on 14 August 1448, at the Battle of Oronichea. The Republic was, thereafter, left with few soldiers to defend Venetian Albania. As a result, the League soon signed peace with the Republic of Venice, while continuing the war against the Ottoman Empire. After the Albanian–Venetian War of 1447–1448, Venice did not seriously challenge Skanderbeg or the League, allowing Skanderbeg to focus his campaigns against the Ottoman Empire. Background In 1444, Skanderbeg had managed to unite the major Albanian princes under his leadership at the League of Lezhë, where a confederation of all the Albanian Principalities was created. Stresses within the alliance were felt, when Nicholas Dukagjini, a member of the Dukagjini family, a powerful family in northern Albania, ambushed and killed Lekë Zaharia Altisferi, prince of Dagnum and also League member. Since Zaharia had no children, he organized the killing to more easily gain Dagnum. The year in which Zaharia was killed is not recorded. A Venetian document dated to 4 January 1445, mentions Zaharia as the once lord of Dagnum which was given to Boxia, Zaharia's mother. The Venetian chronicler Stefano Magno says that Zaharia was killed close to the advent of the year 1445. The two princes had been in dispute over who should marry Irene Dushmani, the only daughter of Lekë Dushmani, prince of Zadrima. In 1445, the Albanian princes had been invited to the wedding of Skanderbeg's younger sister, Mamica, who was being married to Muzaka Thopia. Irene entered the wedding and hostilities began. Dukagjini asked Irene to marry
