of Milan Giangaleazzo Visconti created a power vacuum in northern Italy that enabled expansion of the Domini di Terraferma. The changed climate created by the Ottoman Interregnum and the ensuing Treaty of Gallipoli in 1403 led to a growth of commerce and the acquisition of a new string of fortresses in Greece: Lepanto in 1407, Patras in 1408, Navarino in 1410, and temporarily Thessalonica in 1423. In Dalmatia, where Venice had been forced to cede its possessions to the Kingdom of Hungary by the Treaty of Zadar (1358), it took advantage of the conflict between Ladislaus of Naples and Sigismund over the Hungarian Crown, and in 1409 secured the cession by Ladislaus of several of his Dalmatian domains —Cres, Rab, Pag, Zadar, Vrana and Novigrad— for 100,000 ducats. In 1489, Venice also acquired Cyprus, which it kept until Ottoman conquest in 1570–1571. The Venetian hold over navigation in the Adriatic sea was maintained for centuries, to the extent that it was labeled "Mare di Venezia" (sea of Venice) on maps of the seventeenth and eighteenth centuries. From the 15th century onwards, the history of Venice's overseas empire is dominated by successive Ottoman–Venetian wars. Venice lost many territories but also occasionally gained some, most notably the Peloponnese from the late 1680s to 1715 and the Dalmatian Hinterland also in the 1680s. After that date, the remaining overseas domains, kept until the Fall of the Republic of Venice to Napoleon I in 1797, were all in Istria, Dalmatia, and the Ionian Islands, with none left east of Kythira and Antikythera.

Where there is a difference between the name in Venetian language and standard Italian, the Venetian version is indicated first. Feudal lordships held by Venetians, such as Andrea Ghisi in Tinos and Mykonos, are included.
