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.
