Thrace

• 1. Introduction

  ›

  Thrace sits at the crossroads of three modern nations, Bulgaria, Greece, and Turkey, and yet for most of its history it answered to none of them. Its borders have shifted so many times that a sixth-century geographer, Stephanus of Byzantium, recorded that the region once bore entirely different names altogether: Aria and Perke. Those older names vanished. Thrace endured.

  Bounded by the Balkan Mountains to the north, the Aegean Sea to the south, and the Black Sea to the east, the region has served as a corridor, a battleground, and a homeland. It gave the ancient world some of its most consequential people, from a gladiator who nearly broke Rome to a philosopher who argued that man is the measure of all things. Its name, in Greek mythology, belonged to a heroine and sorceress, daughter of Oceanus and Parthenope, sister of Europa.

  How did a region with no definite boundaries become one of the ancient world's most contested pieces of land? What did it mean to be Thracian? And how does a place that produced Spartacus, Democritus, and Orpheus remain so little discussed? Those are the questions this documentary follows.

• 2. A Land Without Firm Edges

  ›

  Ancient Greek writers used the word "Thrace" to describe all territory north of Thessaly inhabited by Thracian peoples, a zone that, in one ancient source, stood alongside Asia, Libya, and Europa as one of the four divisions of the known Earth. That was not a precise cartographic claim. It was a statement about how vast and formidable the place felt.

  As Greek geographic knowledge grew, the boundaries settled into something more recognizable: the Danube on the north, the Black Sea to the east, northern Macedonia to the south, and Illyria to the west. This largely matched the extent of the Thracian Odrysian kingdom. After the Macedonian conquest, the border with Macedonia shifted from the Struma River to the Mesta River, a concrete territorial adjustment that redrew the region's western limit.

  Roman administration compressed Thrace further. After the administrative reforms of the late third century, the once-expansive Roman province of Thrace was broken into six smaller provinces that together formed the Diocese of Thrace. By the medieval period, the Byzantine theme of Thrace covered only what is now East Thrace. Each contraction left a different inheritance for the people living there.

• 3. Tribes, Warriors, and the Ctistae

  ›

  Thracians recorded no collective name for themselves. The label "Thracian" was applied from outside, by Greeks who looked northward and needed a word for what they saw. What those Greeks saw was not a single people but a mosaic of tribes: the Edones, Bisaltae, Cicones, Bistones, and many others across a landscape divided between mountains and plains.

  The mountain tribes maintained a warrior tradition. The plains tribes were described as more peaceable. That distinction shaped who the Thracians became in the ancient world's imagination: fierce fighters, valued in foreign armies, depicted in carvings at Persepolis and Naqsh-e Rostam after serving under the Achaemenid Persians in the late sixth century BC.

  But warfare was not the whole story. Funeral mounds discovered in Bulgaria show that Thracian kings governed regions with a distinct sense of national identity. And among those communities lived a subculture that stood apart from the warrior norm. A group called the Ctistae, celibate ascetics, lived in Thrace during the classical period and served as philosophers, priests, and prophets. They were not soldiers. They were thinkers, operating in the same landscape as the tribes Homer sent to fight at Troy.

• 4. Myth, Homer, and the Darker Stories

  ›

  In Homer's Iliad, Thracians appear as Trojan allies led by Acamas and Peiros, from the city of Aenus. A second contingent, the Cicones, came from southern Thrace near Ismaros. A third group, from the city of Sestus on the northern side of the Hellespont, formed part of the contingent led by Asius. King Rhesus, another Thracian ruler, makes his own appearance later in the epic. Cisseus, father-in-law to the Trojan elder Antenor, is named as Thracian too.

  Greek mythology gave Thrace a mythical ancestor named Thrax, said to be the son of the war-god Ares and to have resided in the region. The list of Thracian kings in myth grew long: Diomedes, Tereus, Lycurgus, Phineus, Tegyrius, Eumolpus, Polymnestor, Poltys, and Oeagrus, who was the father of Orpheus.

  Ovid's Metamorphoses preserves one of the darkest of these stories. Tereus, King of Thrace, kidnaps his sister-in-law Philomela, holds her captive, rapes her, and cuts out her tongue. Philomela manages to escape. She and her sister Procne take revenge by killing Philomela's son Itys and serving him to Tereus as a meal. The myth ends with all three transformed into birds: Procne becomes a swallow, Philomela a nightingale, and Tereus a hoopoe. The city of Dicaea in Thrace was named after Dicaeus, son of Poseidon, linking the region's geography directly to divine parentage.

• 5. Conquest and Hellenization

  ›

  Persian control came first. The Achaemenid Empire absorbed Thrace as the Satrapy of Skudra following the Scythian campaign of Darius the Great in the late sixth century BC. That Persian presence lasted until the rise of the Delian League.

  Philip II of Macedon and his son Alexander the Great conquered most of Thrace in the fourth century BC. Thracian troops crossed the Hellespont with Alexander during his invasion of the Achaemenid Empire. After Alexander's death, Thrace passed to Lysimachus. He ruled as king until his defeat by Seleucus I Nicator at the Battle of Corupedium in 281 BC.

  Greek colonies had been establishing themselves on the Thracian coast since the eighth century BC. Athens showed particular interest: the numerous finds of Athenian silverware in Thracian tombs point to deep economic and cultural ties before the Peloponnesian War. Spartan and other Doric colonists followed after it. Roman provincial policy then pushed this process further, favoring Hellenization over Romanization. Greek inscriptions in the territory south of the Haemus Mountains confirm the completeness of this linguistic shift. Roman cities such as Nicopolis, Hadrianoupolis, Traianoupolis, and Plotinoupolis became part of this urbanized, Greek-speaking Thrace. The boundary between Greek-speaking and Latin-speaking Thrace ran just above the northern foothills of the Haemus Mountains.

• 6. Rome, Citizenship, and the Barracks Emperors

  ›

  Thrace became a Roman province in 46 AD, after Augustus had moved first to establish indirect rule through a Sapaean client kingdom centered on Bizye, following the Battle of Actium in 31 BC. The Odrysian-Astaean royal family was removed from power in that reorganization. When Rome finally absorbed the region directly, members of the local urban aristocracy began receiving Roman citizenship, and epigraphic evidence shows a large increase in such grants during the reigns of Trajan and Hadrian. In 212 AD, the decree of Emperor Caracalla, known as the constitutio Antoniniana, extended Roman citizenship to all free inhabitants of the empire.

  Thracians moved outward as well. Inscriptions found across the Roman provinces testify to a significant Thracian presence throughout the first and second centuries AD, well beyond the region's borders.

  The most dramatic form of Thracian advancement under Rome came through the military. A number of emperors of the third through fifth centuries had Thraco-Roman backgrounds: Maximinus Thrax, Licinius, Galerius, Aureolus, and Leo the Thracian among them. These men rose from common soldiers in Roman legions to the highest positions of political power, earning the collective nickname Barracks Emperors. The same path ran through the Byzantine period: Basil I, founder of the Macedonian dynasty, was born in Byzantine Thrace, as were John III Doukas Vatatzes and John V Palaiologos.

• 7. A Thousand Years of Conflict

  ›

  By the mid-fifth century, as the Western Roman Empire weakened, Thrace passed from Roman authority to Germanic tribal rulers. For close to a thousand years after that, the region served as a contested zone between larger powers.

  The Byzantine Empire retained control over Thrace until the seventh century, when the northern half was incorporated into the First Bulgarian Empire. The Byzantines regained those lost regions in the late tenth century. The Bulgarians took back the northern half again at the end of the twelfth century. Through the thirteenth century and the first half of the fourteenth, control of the region shifted repeatedly between Bulgaria and the Byzantine Empire, excluding Constantinople itself.

  In 1265, Mongol forces from the Golden Horde, led by Nogai Khan, raided the area. Between 1305 and 1307, the Catalan Company carried out its own raids. In 1352, Ottoman forces made their first incursion into Thrace, and subdued it completely within two decades. They held it for roughly five centuries. Edirne became the Ottoman capital, and after the fall of Byzantium in 1453, that role passed to Constantinople. In Turkish, the region carried the name Rumeli, meaning "Land of the Romans," a label that preserved the memory of Byzantine rule long after the Byzantines themselves were gone.

• 8. Modern Thrace and Its People

  ›

  In 1821, communities across Thrace, including Lavara, Maroneia, Sozopolis, Aenos, Callipolis, and Samothraki, joined the Greek War of Independence. The Congress of Berlin in 1878 placed Northern Thrace inside the semi-autonomous Ottoman province of Eastern Rumelia, which then united with Bulgaria in 1885. The rest of the region was divided between Turkey and Greece after the Balkan Wars, World War I, and the Greco-Turkish War.

  In the summer of 1934, up to ten thousand Jews in Thrace were maltreated, stripped of their property, and forced to leave in what became known as the 1934 Thrace pogroms. Between 1934 and 1938, a large wave of Muslim immigrants known as Goçmenler moved from Bulgaria and Romania into East Thrace.

  The peoples of modern Thrace reflect this layered history. Most of the Bulgarian and Greek population are Orthodox Christians. Most Turkish inhabitants are Sunni Muslims. There are also communities of Muslim Pomaks and Romani. In Western Thrace, inside the Greek province of East Macedonia and Thrace, small numbers of Greek Muslims live alongside Pomaks and Western Thrace Turks. Protagoras of Abdera, who argued around 490-420 BC that man is the measure of all things, came from this same land, as did Democritus, born around 460 BC in the same city, who proposed that all matter consists of indivisible particles he called atoms. Spartacus, the Thracian who led the slave uprising of 73-71 BC known as the Third Servile War, defeated several Roman legions before the revolt was crushed. What the region produced over millennia still shapes how its name is remembered.
