The Duchy of Athens was one of the Crusader states set up in Greece after the conquest of the Byzantine Empire during the Fourth Crusade as part of the process known as Frankokratia, encompassing the regions of Attica and Boeotia, and surviving until its conquest by the Ottoman Empire in the 15th century.
The despot of Epirus was the ruler of the Despotate of Epirus, one of the successor states of the Byzantine Empire in the aftermath of the Fourth Crusade. The name "Despotate of Epirus" and the title "despot of Epirus" are modern historiographical names, and were not in use by the despots themselves. In the Byzantine Empire, the title of despot was a prestigious court title and did not designate rule over some specific territory. Though several of the early Greek rulers of the Epirote realm did use the title of despot, it was never in reference to the lands they governed, but instead in reference to their position in the imperial hierarchy.
Carlo I Tocco was the hereditary Count palatine of Cephalonia and Zakynthos from 1376, and ruled as the Despot of Epirus from 1411 until his death on July 4, 1429.
Carlo II Tocco was the ruler of Epirus from 1429 until his death.
Leonardo III Tocco was the last ruler of the Despotate of Epirus, ruling from the death of his father Carlo II Tocco in 1448 to the despotate's fall to the Ottoman Empire in 1479. Leonardo was one of the last independent Latin rulers in Greece and the last to hold territories on the Greek mainland. After the fall of his realm, Leonardo fled to Italy and became a landowner and diplomat. He continued to claim his titles in exile until his death.
The Duchy of Neopatras was a principality in southern Thessaly, established in 1319. Officially part of the Kingdom of Sicily, itself part of the Crown of Aragon, the duchy was governed in conjunction with the neighbouring Duchy of Athens, it enjoyed a large degree of self-government. From the mid-14th century, the duchies entered a period of decline: most of the Thessalian possessions were lost to the Serbian Empire, internal dissensions arose, along with the menace of Turkish piracy in the Aegean and the onset of Ottoman expansion in the Balkans. Enfeebled, the Catalan possessions were taken over by the Florentine adventurer Nerio I Acciaioli in 1385–1390. The title of Duke of Neopatras was held by the heir of the King of Sicily.
Nerio I Acciaioli or Acciajuoli was the de facto Duke of Athens from 1385 to 1388, after which he reigned uncontested until his death in 1394. Born to a family of Florentine bankers, he became the principal agent of his influential kinsman, Niccolò Acciaioli, in Frankish Greece in 1360. He purchased large domains in the Principality of Achaea and administered them independently of the absent princes. He hired mercenaries and conquered Megara, a strategically important fortress in the Duchy of Athens, in 1374 or 1375. His troops again invaded the duchy in 1385. The Catalans who remained loyal to King Peter IV of Aragon could only keep the Acropolis of Athens, but they were also forced into surrender in 1388.
Antonio I Acciaioli, also known as Anthony I Acciaioli or Antonio I Acciajuoli, was Duke of Athens from 1403.
The County Palatine of Cephalonia and Zakynthos existed from 1185 to 1479 as part of the Kingdom of Sicily. The title and the right to rule the Ionian islands of Cephalonia and Zakynthos was originally given to Margaritus of Brindisi for his services to William II, King of Sicily, in 1185.
The Frankokratia, also known as Latinokratia and, for the Venetian domains, Venetokratia or Enetokratia, was the period in Greek history after the Fourth Crusade (1204), when a number of primarily French and Italian states were established by the Partitio terrarum imperii Romaniae on the territory of the dissolved Byzantine Empire.
The House of Tocco was an Italian noble family from Benevento that came to prominence in the late 14th and 15th centuries, when they ruled various territories in western Greece as Counts Palatine of Cephalonia and Zakynthos and Despots of Epirus. During their brief period of rule in Greece, they were one of the most ambitious and able Latin dynasties in the region, and they were one of the few to leave descendants lasting until modern times.
Guglielmo Tocco was the governor of the Greek island of Corfu in the 1330s and the founder of the Tocco dynasty.
Leonardo I Tocco was the count palatine of the islands of Cephalonia and Zakynthos from 1357 until his death, and later lord of Ithaca, Lefkada, and the port of Vonitsa as well.
The Battle of the Echinades was fought in 1427 among the Echinades islands off western Greece between the fleets of Carlo I Tocco and the Byzantine Empire. The battle was a decisive Byzantine victory, the last in the Empire's naval history, and led to the consolidation of the Peloponnese under the Byzantine Despotate of the Morea.
Leonardo II Tocco was a scion of the Tocco family and lord of Zakynthos, who played an important role as a military leader for his brother, Carlo I Tocco, in early 15th-century western Greece.
Dorotheus I was the Greek Orthodox metropolitan bishop of Athens from c. 1388 to 1392, and the first to reside in the city since 1205.
Carlo III Tocco (1464–1518) was the titular despot of Epirus and count palatine of Cephalonia and Zakynthos from the death of his father Leonardo III Tocco c. 1503 to his own death in 1518. Carlo lived in Rome, where he received pensions from both the Papacy and the Kingdom of Naples. As an adult, Carlo worked as a military officer, serving both the Papacy and Emperor Maximilian I.
Bartolomea Acciaioli or Acciajuoli was the wife of Theodore I Palaiologos, Despot of the Morea from 1385. She was the elder daughter of Nerio I Acciaioli, who held large estates in Frankish Greece. She was famed for her beauty and her father gave her in marriage to the Despot to seal their alliance. Since her father and husband's relations deteriorated in the early 1390s, her father disinherited her in favor of her younger sister, Francesca, and their illegitimate brother, Antonio. Barolomea died childless.
Leonardo IV Tocco was the titular Despot of Epirus and Count Palatine of Cephalonia and Zakynthos from the death of his father Carlo III Tocco in 1518 to his own death in 1564. His mother was Andronica Arianiti, daughter of Constantine Arianiti, also a claimant to various lands in Greece. From his maternal grandfather, Leonardo was granted the fortress of Refrancore, which he held under the title signore (lord).
Don Antonio Tocco was the last titular Despot of Epirus and Count Palatine of Cephalonia and Zakynthos, claiming these titles from the death of his father Leonardo V Tocco in 1641 until he abandoned them in 1642, substituting them for the title of Prince of Achaea, which he used until his death in 1678.
