Francesco I Gattilusio
Italian patrician and Archon of Lesbos
Francesco I Gattilusio (Ancient Greek: Φραντζέσκος Γατελιοῦζος, romanized: Phrantzéskos Gatelioûzos; c. 1325 – 6 August 1384) was an Italian noble, the first member of the Gattilusio family to rule the Aegean island of Lesbos as a vassal of the Byzantine emperor.
Freebooter
The Gattilusio family came from the Republic of Genoa. The parents of Francesco and his brother Niccolò are not known, although based on the heraldic evidence of their inscriptions, Anthony Luttrell argues that their mother was a member of the Doria family.
Francesco enters the historical record as a freebooter or pirate. In 1354, Francesco and his crew landed on Tenedos. The island served at the time as residence to John V Palaiologos, one of three co-emperors to the throne of the Byzantine Empire, the others being his father-in-law John VI Kantakouzenos and brother-in-law Matthew Kantakouzenos. John V and his in-laws were in conflict at the time.
John V and Francesco entered an alliance to enable John to regain control of Constantinople. In return, he would be given the hand of Irene renamed Maria Palaiologina, a sister of John V, in marriage.
In early December 1354, Francesco led a fleet to Constantinople.
