The 13th Century Latin Empire: A Patchwork of Loosely Arranged Fiefdoms and Principalities Nominally under the Central Authority of Constantinople

In earlier blogs we have seen how the ruling elites from aristocratic Byzantine Greek families managed to carve out chunks of the vast Byzantine Empire and establish their own imperial dynasties in the early 13th century. The three rump states of Trebizond, Nicaea and Epirus all came into being at the expense of the Latin Empire. Their action was a reaction to the Crusade leaders from Catholic Europe who had deposed the old regime in Constantinople (the Angelos dynasty) and proceeded to divvy up the imperial Byzantine lands among themselves and their financial backers. The latter, representing the political and commercial interests of Venice, a key player in the whole enterprise, did very well, netting three-eighths of the old empire’s strategic possessions including Crete) and innumerable war spoils from Byzantium. The crusader hierarchy elected from their leaders, Baldwin, Count of Flanders and Hainaut, as the first Latin emperor of Constantinople.

Nomenclature: the term “Latin Empire” was not contemporary to the period, and was only applied by historians in the 16th century to distinguish the Crusader feudal state from the classical Roman Empire and the  Byzantine Empire (both of which called itself “Roman”). The term “Latin” was chosen because the crusaders—Franks, Venetians, and other Westerners—were Roman Catholic and used Latin as their liturgical and scholarly language in contrast to the Eastern Orthodox locals who used Greek in both liturgy and common speech. The Byzantines referred to the Latin Empire as the Frankokratia (“rule of the Franks”) or the Latinokratia (“rule of the Latins”). The crusaders themselves in documents tended to use the expression “Empire of Constantinople” or more commonly referred to the empire as “Romania” and themselves as “Romans” [Jacobi, David (1999), “The Latin empire of Constantinople and the Frankish states in Greece”, in Abulafia, David (ed.), The New Cambridge Medieval History, Vol. V: c. 1198–c. 1300, (Cambridge University Press), pp. 525–542].

Attempts by the Crusader state to expand its imperial boundaries was hampered by constant conflict with its neighbours, the Bulgarian Empire to the north and the three Byzantine successor states. Baldwin I didn’t last long as Latin emperor, his army was crushed by Tsar Kaloyan’s Bulgarian troops at the Battle of Adrianople, with Baldwin captured and dying in prison later in 1205. Latin fortunes improved for a while with his successor, Henry of Flanders (for competence, the pick of the Latin emperors by a wide margin), who won back most of the lost territory in Thrace and concluded a successful peace treaty with the Bulgarian enemies after marrying Kaloyan’s daughter.

After Henry’s death there was a swift turnover of Latin regents🄰 and the Despotate of Epirus stepped up its campaign to wrest the Kingdom of Thessalonica from the Latin Empire, finally capturing it in 1224. The threat from Epirus receded however after the Epirotes were badly beaten by the Bulgarians under Tsar John Asen (Battle of Klokotnitsa, 1230)…around this time the burgeoning power of the Empire of Nicaea replaced Epirus as the principal Byzantine threat to the Latin state.

The Latin empire, now led by Baldwin II (known as Porphyrogenitus – “born to the purple”), was economically diminished and reduced in area to little beyond the city of Constantinople itself. Baldwin spent much of his long reign as emperor scurrying round the courts of Western Europe cap-in-hand in a largely fruitless quest for aid for Constantinople’s impoverished state. Nicaea meanwhile was tightening the screws on Constantinople. In 1259 the Nicaeans defeated the Principality of Achaea, a vassal state of the Latin Empire (Battle of Pelagonia). The loss of Achaea, the strongest of the Frankish states in Greece, was a decisive blow for the Latins in the defence of their imperial capital.

After a failed attempt to take Constantinople in 1260 the Niceans were ultimately successful in the endeavour the following year, without planning to do so. A small force of Nicaea on a scouting mission in the proximity of Constantinople’s walls fortuitously discovered that virtually the entire garrison and the Venetian fleet had temporarily vacated the city, leaving it defenceless. Seizing the opportunity the Nicaeans located an unguarded entry point and stormed the city, capturing it in the name of Nicaea’s emperor, Michael VIII Palaiologos. The Latins had lost, irrevocably, their Byzantine empire, with their remaining possessions reduced to a few enclaves in southern Greece, the title of emperor was nonetheless retained, in name only, by a succession of claimants up until 1383.

Composition of the Latin Empire: The empire was a feudalistic polity, comprising numerous vassal states or fiefdoms, including the Duchy of Philippopolis (northern Thrace); Lemnos (island in the Aegean); the Kingdom of Thessalonica (Macedonia and Thessaly)🄱; the County of Salona (modern Amfissa in central Greece); the Marquisate of Bodonitsa (central Greece)🄲; the Principality of Achaea (encompassing the Morea or Peloponnese peninsula🄳; the Duchy of Athens (encompassing Attica, Boeotia and parts of southern Thessaly); the Duchy of Naxos (or of the Archipelago) (encompassing most of the Cyclades islands); the Triarchy of Negroponte (island of Negroponte (modern Euboea); the Principality of Adrianople (modern Edirne, eastern Thrace)🄴; the County palatine of Cephalonia and Zakynthos (several Ionian islands)🄵. All of these entities and regions within the Byzantine world were ultimately absorbed by the Ottoman Empire.

Encumbrances to empire: The Latin Empire was intended to recreate the Roman Empire in an eastern setting (Byzantium) with a Catholic monarchy, but as a political entity it only lasted a mere 57 years (cf. the preceding Byzantine Empire which, established by Constantine in 330 CE, was in its 874th year when Constantinople was sacked). The Latin Empire failed abjectly to establish itself as an enduring power, the seeds of which were present from the onset. The Crusade leaders started dividing up who gets what part of the Byzantine “pie” before they had started the process of conquest in some of the regions (in fact the conquest of the former Byzantine imperial space was never completed). The approach to the whole task lacked cohesion. Moreover, the “individual expeditions undertaken by various Latin knights and commoners, as well as by the Venetian state, prevented systematic implementation of the partition plan”. The territories the Latins occcupied in the European part of “Romania“ and the Aegean, as a consequence, became “a mosaic of (mainly small) political entities”[David Jacoby, ‘After the fourth crusade: The Latin empire of constantinople and the Frankish states’, (Jan. 2009) DOI:10.1017/CHOL9780521832311.028 in The Cambridge History of the Byzantine Empire c.500–1492 (pp.759-778)]. These separate smaller “principalities and regions were in principle dependent on the Latin emperor’s suzerainty “ but were in “de facto (terms) practically independent entities” [Filip Van Tricht, The Latin Renovatio of Byzantium: The Empire of Constantinople (1204–1228) (2011)]. All of this worked against the task of making the empire centrally unified and coherent. Allied to this, Venice’s singular pursuit of its self-interest by its nature worked to the detriment of crusader goals. Another factor weighing down the Latin Empire was its economic decline, heavily in debt to the Venetians, Latin emperors were forced to resort to hocking their royal jewels to meet their costs. A succession of wars with the Bulgarian Empire and the Byzantine claimants proved costly. By the time of the last Latin emperor, Baldwin II, the population of the once-great metropolis Constantinople had plummeted alarmingly.

🄰 this period was the Latinokrakaria

🄱 Thessalonica’s short history as an quasi-independent entity was characterised by ongoing warfare, principally with the Bulgarian Empire before being conquered by Epirus (1224)

🄲 both Salona and Bodonitsa originally were vassal states of the Kingdom of Thessalonica

🄳 Achaea, the strongest of the Crusader states, exercising suzerainty over the Lordship of Argos and Nauplia. Achaea continued to prosper even after the eclipse of the Latin Empire. Its main rival was the Byzantine Despotate of the Morea which eventually succeeded in conquering the principality

🄴 the Principality of Adrianople committed itself to a course of fluidity in regard to the dominant powers venturing into its orbit, shifting allegiances readily from Constantinople to Epirus to Bulgaria to Nicaea during the 1220s for the quid pro qua of retaining its local autonomy [Filip Van Tricht, ‘The Byzantino-Latin Principality of Adrianople and the Challenge of Feudalism (1204/6–ca. 1227/28)’, www.core.ac.uk]

🄵 in addition to these both the Genoese and Venetians possessed colonies in the Greek islands and in mainland Greece at one time or other (Genoa: including Lesbos, Lemnos, Thasos, Samothrace, Ainos, Lordship of Chios and port of Phocaea; Venice: including Crete, Corfu, Lefkas, Tinos and Mykonos)
