 As a province of the Byzantine Empire, Lemnos belonged to the theme of the Aegean Sea, and was a target of Saracen raids in the 10th century and of Seljuk raids in the 11th century.Following the dissolution and division of the Empire after the Fourth Crusade, Lemnos (known by Westerners as "Stalimene") was apportioned to the Latin Empire, and given as a fief to the Navigajoso family under the Venetian (or possibly of mixed Greek and Venetian descent) "megadux" Filocalo Navigajoso.Filocalo died in 1214, and was succeeded by his son Leonardo and his daughters, who partitioned the island into three fiefs between them.
