Historiographical synthesis & structured realm registry
The Duchy of the Archipelago, also known as Duchy of Naxos or Duchy of the Aegean, was a maritime state created by Venetian interests in the Cyclades archipelago in the Aegean Sea, in the aftermath of the Fourth Crusade, centered on the islands of Naxos and Paros. It included all the Cyclades. In 1537, it became a tributary of the Ottoman Empire, and was annexed by the Ottomans in 1579; however, Christian rule survived in islands such as Sifnos and Tinos.

Later history
Twenty-one dukes of the two dynasties ruled the Archipelago, successively as vassals of the Latin Emperors at Constantinople, of the Villehardouin dynasty of princes of Achaea, of the Angevins of the Kingdom of Naples (in 1278), and after 1418 of the Republic of Venice.
In 1248, the suzerainty of the Duchy was nominally granted by the Latin Emperor Baldwin II to William of Villehardouin, Prince of Achaea. Marco II Sanudo lost many of the islands, except Naxos and Paros, to the forces of the renewed Byzantine Empire under the admiral Licario in the late 13th century. The Byzantine revival was to prove short-lived, though, as they relinquished control of their gains in 1310.
Legacy and influence
Today, Cyclades islands such as Syros and Tinos have some entirely Catholic villages and parishes, while many Greeks from the Cyclades have surnames with a distinctly Italo-Venetian origin e.g. Venieris, Ragousis, Dellaportas, Damigos etc.
Background and establishment of the Duchy
The Italian city-states, especially the Republic of Genoa, Pisa, and Venice, had been interested in the islands of the Aegean long before the Fourth Crusade. There were Italian trading colonies in Constantinople and Italian pirates frequently attacked settlements in the Aegean in the 12th century. After the collapse and partitioning of the Byzantine Empire in 1204, in which the Venetians played a major role, Venetian interests in the Aegean could be more thoroughly realized.
The Duchy of the Archipelago was created in 1207 by the Venetian nobleman Marco Sanudo, a participant in the Fourth Crusade and nephew of the former Doge Enrico Dandolo, who had led the Venetian fleet to Constantinople. This was an independent venture, without the consent of the Latin emperor Henry of Flanders.
