Thomas Preljubović (Serbian : Тома Прељубовић / Toma Preljubović; Greek : Θωμάς Κομνηνός Παλαιολόγος, Thōmas Komnēnos Palaiologos) was ruler of the Despotate of Epirus in Ioannina from 1366 to his death on December 23, 1384. He also held the title of Albanian-slayer after receiving aid from the Ottoman Empire against the Albanian ruler of the Despotate of Arta, Gjin Bua Shpata, after failing to do so independently. [1]



Thomas was the son of caesar Gregorios Preljub (Greek : Grēgorios Prealimpos), the Serbian governor of Thessaly, who died in late 1355 or early 1356. His mother Irene was a daughter of Stephen Uroš IV Dušan of Serbia [2] and Helena of Bulgaria.


After the violent death of his father, Thomas' claim to Thessaly was asserted by his mother Irene, but they were forced to flee to Serbia by the advance of Nikephoros II Orsini in 1356. Here, Irene married Radoslav Hlapen, the ruler of Vodena, who took Thomas under his wing.

During the absence of Thessaly's new ruler, Simeon Uroš Palaiologos, in the Despotate of Epirus in 13591360, Hlapen invaded Thessaly, attempting to win it for his stepson. Although Simeon Uroš managed to contain the invasion, he was forced to cede Kastoria to Thomas and to marry him to his daughter Maria. Over the next several years, Simeon Uroš recognized that he could not assert effective authority over most of Epirus and delegated power in Arta and Angelokastron to local Albanian chieftains. In 1366 the citizens of Ioannina, the last major fortress to remain under Simeon Uroš's control, sent him a petition to appoint a governor who could protect them from the raids of Albanian clansmen.

Simeon Uroš responded by designating Thomas as his governor and forwarding the Ioanninan and Vagenetian (Thesprotian) embassy to him. Thomas entered Ioannina sometime in 1366 or 1367. Thomas' reign in Epirus is reflected in most detail in the so-called Chronicle of Ioannina, which is deeply prejudiced [3] and hostile against Preljubović. [4] It represents him as a cruel and capricious tyrant. Thomas seized various properties of the Church of Ioannina and awarded them to his Serbian retainers. In 1382 a new appointee to the local archbishopric, Matthew, was sent out from Constantinople, and invested Thomas with the title of despotes on behalf of the Byzantine Emperor John V Palaiologos. Nevertheless, later Thomas quarreled with the archbishop and exiled him from Ioannina.

Thomas was also accused of persecuting the local nobility, which inspired a series of revolts against his rule. In addition to seizing ecclesiastical and private property, Thomas established new taxes and monopolies on various commodities, including fish and fruit. In addition to relying on his military forces to enforce these imposts, Thomas waged a continuous war against the Albanians of Arta and Angelokastron.

Soon after taking possession of Ioannina, Thomas was unsuccessfully besieged by Albanian nobleman, Peter Losha of Arta.[ citation needed ] Thomas betrothed his daughter to Losha's son in 1370, satisfying the Albanians and ending conflicts. [5] In 1374, Pjetër Losha died of the plague in Arta, after which Gjon Shpata took over the city. [5] At this time he was not bound by agreement to Thomas; he laid siege to Ioannina and ravaged the country-side. [5] Thomas brought peace when he betrothed his sister Helena to Gjon Shpata the following year. [5] Attacks on Ioannina continued, however, by the Malakasioi, who were finally defeated by Thomas (1377 and 1379). [5] In May 1379, Gjon Shpata devastated the country-side of Ioannina. [6]

After repeated failure, Thomas turned for help to his Frankish and then his Ottoman neighbors. The latter responded promptly and dispatched an auxiliary force in 1381. Thomas put this force to good use and conquered many fortresses from his enemies in 13811384. He was given the epithet "Albanian-Slayer" (Αλβανοκτόνος, Albanoktonos).

However, Thomas had come to be on bad terms with his wife Maria, who participated in the subsequent conspiracy against her husband. On December 23, 1384, Thomas was assassinated by his guards. [7] the population of Ioannina swore allegiance to Maria and invited her brother John Uroš Doukas Palaiologos to come and advise her in the government.


Preljubović is generally treated in a negative outlook in contemporary sources. The Chronicle of Ioannina, written about his rule in Ioannina, regularly describes him as "wicked", a "merciless sadist" and a "murderer". In the Chronicle, Preljubović is described as "greedy and avaricious" and special mention is made to his tyrannical actions towards the church, the nobility and regular citizens of Ioannina. [8]


By Tsarevna Princess Jerina (daughter of Tsar Dusan), Thomas II Preljubović had at least one daughter:

By his wife Maria Angelina Doukaina Palaiologina Thomas II possibly had a son:

Despotate of Epirus Former country

The Despotate of Epirus was one of the Greek successor states of the Byzantine Empire established in the aftermath of the Fourth Crusade in 1204 by a branch of the Angelos dynasty. It claimed to be the legitimate successor of the Byzantine Empire, along with the Empire of Nicaea and the Empire of Trebizond, its rulers briefly proclaiming themselves as Emperors in 1227–1242. The term "Despotate of Epirus" is, like "Byzantine Empire" itself, a modern historiographic convention and not a name in use at the time.

Despot of Epirus

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.

Arta, Greece Place in Greece

Arta is a city in northwestern Greece, capital of the regional unit of Arta, which is part of Epirus region. The city was known in ancient times as Ambracia. Arta is known for the medieval bridge over the Arachthos River. Arta is also known for its ancient sites from the era of Pyrrhus of Epirus and its well-preserved 13th-century castle. Arta's Byzantine history is reflected in its many Byzantine churches; perhaps the best known is the Panagia Paregoretissa, built about 1290 by Despot Nikephoros I Komnenos Doukas.

Nikephoros II Orsini - Doukas, was the ruler of Epirus from 1335 to 1338 and from 1356 until his death in 1359.

Simeon Uroš Emperor of Serbs and Greeks

Simeon Uroš, nicknamed Siniša (Синиша), was a self-proclaimed Emperor of Serbs and Greeks, from 1356 to 1370. He was son of Serbian King Stefan Dečanski and Byzantine Princess Maria Palaiologina. Initially, he was awarded the title of despot in 1346, and appointed governor of southern Epirus and Acarnania in 1347 by his half-brother, Serbian Emperor Stefan Dušan. After Dušan's death in 1355, the Serbian throne passed to Dušan's son Stefan Uroš V, but despot Simeon decided to seize the opportunity in order to impose himself as co-ruler and lord of all southern provinces of the Serbian Empire. That led him to conflict with his nephew in 1356, when Simeon started to expand his control in southern regions of the Empire, trying to take Thessaly and Macedonia. He proclaimed himself Emperor of the Serbs and Greeks, creating a separate state, centered in regions of Thessaly and Epirus, where he ruled until his death in 1370. He was succeeded by his son Jovan Uroš.

Maria Angelina Doukaina Palaiologina Basilissa of Epirus

Maria Angelina Doukaina Palaiologina or Marija Angelina Nemanjić or Anna Maria Angelina Doukaina Palaiologina was a Byzantine Greek-Serbian aristocrat and the self-proclaimed basilissa of Epirus from 1384–85, succeeding the rule of her murdered husband Thomas Preljubović. Maria and her husband were a famed couple as patrons of the arts during Tomo's rule of Ioannina from 1366 to 1384. She is even portrayed in the icons.

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.

John Spata was an Albanian ruler in western Greece with the title of Despot. Together with Peter Losha, he led raids into Epirus, Acarnania and Aetolia in 1358. He was recognized as Despot by titular Eastern Roman Emperor in the early 1360s and ruled Aetolia (1360s–?), Angelokastron (?–1399), Naupactus (1378–99), and Arta (1370s–99). Fought against many factions and was undefeated in 42 years of his rule.

Despotate of Arta

The Despotate of Arta was a despotate established by Albanian rulers during the 14th century, after the defeat of the local Despot of Epirus, Nikephoros II Orsini, by Albania tribesmen in the Battle of Achelous in 1359 and ceased to exist in 1416, when it passed to Carlo I Tocco.

Muriki or Maurice Spata ; fl. 1399–1414) was the ruler of Arta from late 1399/early 1400 until his death in 1414 or 1415. Maurice's reign was dominated by his wars with Carlo I Tocco. Maurice was able to defend his capital of Arta, but despite some victories failed to prevent the fall of Ioannina to Tocco. As a result, his brother Yaqub Spata who succeeded him was defeated in October 1416, ending the Despotate of Arta.

Peter Losha

Pjetër Losha was an Albanian clan leader in medieval Epirus. He belonged to the Losha fis and was the leader of a combined force of his own clan and the fis of Mazaraki and Malakasi. In 1360, he became Despot of Arta, Rogoi and the area of Amphilochia. He died in 1374 and was succeeded by his close ally, John Spata. The Chronicle of the Tocco is an important primary source for his life and the Albanians in medieval Epirus in general.

The term Albanian principalities refers to a number of principalities created in the Middle Ages in Albania and the surrounding regions in the western Balkans that were ruled by Albanian nobility. The 12th century marked the first Albanian principality, the Principality of Arbanon. It was later, however, in the 14th century and the beginning of the 15th century that these principalities became stronger, especially with the fall of the Serbian Empire. Some of these principalities were notably united in 1444 under the military alliance called League of Lezhë.

After the weakening of the Byzantine Empire and the Bulgarian Empire in the middle and late 13th century, the northern territory of modern day Albania became part of Serbia. Firstly, as part of Serbian Grand Principality and later as part of Serbian Empire. The southern part was governed by the semi-independent, Serbian-ruled Despotate of Epirus. Between 1272 and 1368, some areas of the modern-day state were also ruled by the Angevins as the Kingdom of Albania. In the late 14th century, Albanian Principalities were created throughout Albania.

The Battle of Achelous took place in 1359 near the river Achelous, in Aetolia, modern Greece fought between Albanian troops, under Peter Losha and John Spata, and forces of the Despotate of Epirus, under Nikephoros II Orsini. The Albanians defeated Orsini's army, which suffered massive casualties during the battle. The battle established two despotates from regions previously part of the Despotate of Epirus: the Despotate of Arta and the Despotate of Angelokastron and Lepanto.
