The term derives from the name given by the Orthodox Greeks to the Western EuropeanLatin ChurchCatholics: "rule of the Franks or Latins". The span of the Frankokratia period differs by region: the political situation proved highly volatile, as the Frankish states fragmented and changed hands, and the Greek successor states re-conquered many areas.
The Latin Empire (1204-1261), centered in Constantinople and encompassing Thrace and Bithynia, was created as the successor of the Byzantine Empire after the Fourth Crusade, while also exercising nominal suzerainty over the other Crusader principalities. Its territories were gradually reduced to little more than the capital, which was eventually captured by the Empire of Nicaea in 1261.
Lemnos formed a fief of the Latin Empire under the Venetian Navigajoso family from 1207 until conquered by the Byzantines in 1278. Its rulers bore the title of megadux ("grand duke") of the Latin Empire.
The County of Salona (1205-1410), centred at Salona (modern Amfissa), like Bodonitsa, was formed as a vassal state of the Kingdom of Thessalonica, and later came under the influence of Achaea. It came under Catalan and later Navarrese rule in the 14th century, before being sold to the Knights Hospitaller in 1403. It was finally conquered by the Ottomans in 1410.
The Marquisate of Bodonitsa (1204-1414), like Salona, was originally created as a vassal state of the Kingdom of Thessalonica, but later came under the influence of Achaea. In 1335, the Venetian Giorgi family took control, and ruled until the Ottoman conquest in 1414.
The Principality of Achaea (1205-1432), encompassing the Morea or Peloponnese peninsula. It quickly emerged as the strongest state, and prospered even after the demise of the Latin Empire. Its main rival was the Byzantine Despotate of the Morea, which eventually succeeded in conquering the Principality. It also exercised suzerainty over the Lordship of Argos and Nauplia (1205-1388).
The Duchy of Naxos or of the Archipelago (1207-1579), founded by the Sanudo family, it encompassed most of the Cyclades. In 1383, it passed under the control of the Crispo family. The Duchy became an Ottoman vassal in 1537, and was finally annexed to the Ottoman Empire in 1579.
The Triarchy of Negroponte (1205-1470), encompassing the island of Negroponte (Euboea), originally a vassal of Thessalonica, then of Achaea. It was fragmented into three baronies (terzi or "triarchies") run each by two barons (the sestieri). This fragmentation enabled Venice to gain influence acting as mediators. By 1390 Venice had established direct control of the entire island, which remained in Venetian hands until 1470, when it was captured by the Ottomans.
Rhodesbecame the headquarters of the military monastic order of the Knights Hospitaller of Saint John in 1310, and the Knights retained control of the island (and neighbouring islands of the Dodecanese island group) until ousted by the Ottomans in 1522.
Genoese attempts to occupy Corfu and Crete in the aftermath of the Fourth Crusade were thwarted by the Venetians. It was only during the 14th century, exploiting the terminal decline of the Byzantine Empire under the Palaiologos dynasty, and often in agreement with the weakened Byzantine rulers, that various Genoese nobles established domains in the northeastern Aegean:
The Gattilusi family established a number of fiefs, under nominal Byzantine suzerainty, over the island of Lesbos (1355-1462) and later also the islands of Lemnos, Thasos (1414-1462) and Samothrace (1355-1457), as well as the Thracian town of Ainos (1376-1456).
Crete, also known as Candia, (1211-1669), one of the Republic's most important overseas possessions, despite frequent revolts by the Greek population, it was retained until captured by the Ottomans in the Cretan War.
Corfu (1207-1214 and 1386-1797), was captured by Venice from its Genoese ruler shortly after the Fourth Crusade. The island was soon retaken by the Despotate of Epirus, but captured in 1258 by the Kingdom of Sicily. The island remained under Angevin rule until 1386, when Venice reimposed its control, which would last until the end of the Republic itself.
Lefkas (1684-1797), originally part of the Palatine county and the Orsini-ruled Despotate of Epirus, it came under Ottoman rule in 1479, and was conquered by the Venetians in 1684, during the Morean War.
Zakynthos (1479-1797), originally part of the Palatine county and the Orsini-ruled Despotate of Epirus, it fell to Venice in 1479
Cephalonia and Ithaca (1500-1797), originally part of the Palatine county and the Orsini-ruled Despotate of Epirus, they came under Ottoman rule in 1479, and were conquered by the Venetians in December 1500.
Athens, acquired in 1394 from the heirs of Nerio I Acciaioli, but lost to the latter's bastard son Antonio in 1402-03, a fact recognized by the Republic in a treaty in 1405.
Parga, port town on the coast of Epirus, acquired in 1401. It was governed as a dependency of Corfu, and remained so even after the end of the Venetian Republic in 1797, finally being ceded by the British to Ali Pasha in 1819.
Lepanto (Naupaktos), port in Aetolia, briefly seized by a Venetian captain in 1390, in 1394 its inhabitants offered to hand it over to Venice, but were rebuffed. Finally sold to Venice in 1407 by its Albanian ruler, Paul Spata, lost to the Ottomans in 1540.
