Chapter one

Political context and development

Background

The Gattilusio lordships in the Aegean had their origin in the events of November 1354, when the Genoese pirate Francesco Gattilusio was enlisted by the Byzantine Emperor John V (1341–91) to help him seize from his father-in-law, co-emperor and rival John VI (1347–54). The ensuing coup d’etat was a success, and having taken control of the imperial capital John V honoured his ally with marriage to his sister and possession of the island of Lesbos, com- monly known by the name of its chief city Mytilene.1 The change of regime in Constantinople was the decisive blow in a long power-struggle which had robbed the of most of its remaining strength. On the death of the Emperor Andronikos III Palaiologos (1328–41) Byzantium, though greatly diminished in size and institutional strength from its heyday, or even from the time of Michael VIII (1259–82), remained a significant regional power. Its position in Europe and the Aegean had lately rebounded somewhat from earlier losses. This com- pensated to some extent for the disasters of the late thirteenth and early fourteenth century, which had seen the loss of virtually all the Byzantine territories in Asia, and the empire retained the scope for further modest recovery. It still possessed a degree of military and diplomatic clout and held a continuous block of Balkan territory stretching from the Bosphorus to the Adriatic and the Gulf of Corinth, as well as the islands of the northern Aegean, some residual minor footholds in Anatolia and the south-­eastern portion of the , then commonly known as the .2 All

Albania, Epiros, Thessaly and most of passed permanently from Byzantine control, leaving only the war-ravaged province of and an enclave around Thessalonike in addition to the islands, the Morea and the last scraps of Byzantine Asia.6 The most far-reaching consequence of the civil war only became apparent in the years that followed. The competing Byzantine factions had enlisted the military help of the various Turkish emirates which had already effectively completed the conquest of the empire’s Asiatic prov- inces. While many of the Turks who had crossed over into Europe to serve in the civil wars or against the Serbs had returned home with their pay and plunder, some had remained at large in Thrace, turning to pillage on
