Thrace

Thrace (, ; Тракия; Θράκη; Trakya) is a geographical and historical region in Southeast Europe. Bounded by the Balkan Mountains to the north, the Aegean Sea to the south, and the Black Sea to the east, it comprises present-day southeastern Bulgaria (Northern Thrace), northeastern Greece (Western Thrace), and the European part of Turkey (East Thrace), roughly the Roman Province of Thrace. Lands also inhabited by ancient Thracians extended in the north to modern-day Northern Bulgaria and Romania and to the west into Macedonia.

Etymology
The word Thrace, from ancient Greek Thrake (Θρᾴκη), referred originally to the Thracians (ancient Greek Thrakes Θρᾷκες), an ancient people inhabiting Southeast Europe. The name Europe (ancient Greek Εὐρώπη), also at first referred to this region, before that term expanded to include its modern sense. The region could have been named after the principal river there, Hebros, possibly from the Indo-European arg "white river" (the opposite of Vardar, meaning "black river"), According to an alternative theory, Hebros means "goat" in Thracian.

According to Stephanus of Byzantium, long before the ancient Greeks started referring to the region as Thrace, it was known as Aria (Αρια) and Perki (Περκη).

In Turkey, it is commonly referred to as Rumeli, "Land of the Romans", which was the name traditionally given by Turkic societies to the Byzantine Empire and Orthodox Christians.

Mythology
In terms of ancient Greek mythology the name appears to derive from the heroine and sorceress Thrace, who was the daughter of Oceanus and Parthenope, and sister of Europa.

Borders
The historical boundaries of Thrace have varied. The ancient Greeks employed the term "Thrace" to refer to all of the territory which lay north of Thessaly inhabited by the Thracians, a region which "had no definite boundaries" and to which other regions (like Macedonia and even Scythia) were added. In one ancient Greek source, the very Earth is divided into "Asia, Libya, Europa and Thracia". As the Greeks gained knowledge of world geography, "Thrace" came to designate the area bordered by the Danube on the north, by the Euxine Sea (Black Sea) on the east, by northern Macedonia in the south, and by Illyria to the west. This largely coincided with the Thracian Odrysian kingdom, whose borders varied over time. After the Macedonian conquest, this region's former border with Macedonia was shifted from the Struma River to the Mesta River. This usage lasted until the Roman conquest. Henceforth, (classical) Thrace referred only to the tract of land largely covering the same extent of space as the modern geographical region. In its early period, the Roman province of Thrace was of this extent, but after the administrative reforms of the late 3rd century, Thracia's much reduced territory became the six small provinces which constituted the Diocese of Thrace. The medieval Byzantine theme of Thrace contained only what today is East Thrace.

Cities
The largest cities of Thrace are: Istanbul, Plovdiv, Çorlu, Tekirdağ, Burgas, Edirne, Stara Zagora, Sliven, Yambol, Haskovo, Komotini, Alexandroupoli, Xanthi, and Kırklareli.

Demographics and religion
Most of the Bulgarian and Greek population are Orthodox Christians, while most of the Turkish inhabitants of Thrace are Sunni Muslims.

Ancient Greek mythology
Ancient Greek mythology provides the Thracians with a mythical ancestor Thrax, the son of the war-god Ares, who was said to reside in Thrace. The Thracians appear in Homer's Iliad as Trojan allies, led by Acamas and Peiros. Later in the Iliad, Rhesus, another Thracian king, makes an appearance. Cisseus, father-in-law to the Trojan elder Antenor, is also given as a Thracian king.

Homeric Thrace was vaguely defined, and stretched from the River Axios in the west to the Hellespont and Black Sea in the east. The Catalogue of Ships mentions three separate contingents from Thrace: Thracians led by Acamas and Peiros, from Aenus; Cicones led by Euphemus, from southern Thrace, near Ismaros; and from the city of Sestus, on the Thracian (northern) side of the Hellespont, which formed part of the contingent led by Asius. Ancient Thrace was home to numerous other tribes, such as the Edones, Bisaltae, Cicones, and Bistones in addition to the tribe that Homer specifically calls the "Thracians".

Greek mythology is replete with Thracian kings, including Diomedes, Tereus, Lycurgus, Phineus, Tegyrius, Eumolpus, Polymnestor, Poltys, and Oeagrus (father of Orpheus).

Thrace is mentioned in Ovid's Metamorphoses, in the episode of Philomela, Procne, and Tereus: Tereus, the King of Thrace, lusts after his sister-in-law, Philomela. He kidnaps her, holds her captive, rapes her, and cuts out her tongue. Philomela manages to get free, however. She and her sister, Procne, plot to get revenge, by killing her son Itys (by Tereus) and serving him to his father for dinner. At the end of the myth, all three turn into birds – Procne into a swallow, Philomela into a nightingale, and Tereus into a hoopoe.

The city of Dicaea in Thrace was named after the son of Poseidon, Dicaeus.

Ancient and Roman history
Indigenous Thracians were divided into numerous tribes. The first to take greater control of Thrace, in part or whole, were the Achaemenian Persians in the late 6th century BC. The region was incorporated into their empire as the Satrapy of Skudra, after the Scythian campaign of Darius the Great. Thracian soldiers were used in Persian armies and are depicted in carvings of the Persepolis and Naqsh-e Rostam. Persians' presence in Thracia lasted for more than a century, ending with the conquests in the 4th century BC by Alexander the Great of Macedon, who divided the vast realm between his generals. Notably, Thracian troops are known to have accompanied Alexander when he crossed the Hellespont which abuts Thrace, during the invasion of the Persian Empire itself.

The Thracians recorded no collective name for themselves; terms such as Thrace and Thracians were assigned by the Greeks.

Divided into separate tribes, the Thracians did not form any lasting political organizations until the founding of the Odrysian state in the 4th century BC. Like Illyrians, the locally ruled Thracian tribes of the mountainous regions maintained a warrior tradition, while the tribes based in the plains were purportedly more peaceable. Recently discovered funeral mounds in Bulgaria suggest that Thracian kings did rule regions of Thrace with distinct Thracian national identity.

During this period, a subculture of celibate ascetics called the Ctistae lived in Thrace, where they served as philosophers, priests, and prophets.

Sections of Thrace particularly in the south started to become hellenized before the Peloponnesian War as Athenian and Ionian colonies were set up in Thrace before the war. Spartan and other Doric colonists followed them after the war. The special interest of Athens to Thrace is underlined by the numerous finds of Athenian silverware in Thracian tombs. In 168 BC, after the Third Macedonian war and the subjugation of Macedonia to the Romans, Thrace also lost its independence and became tributary to Rome. Towards the end of the 1st century BC Thrace lost its status as a client kingdom as the Romans began to directly appoint their kings. This situation lasted until 46 AD, when the Romans finally turned Thrace into a Roman province (Romana provincia Thracia).

During the Roman domination, within the geographical borders of ancient Thrace, there were two separate Roman provinces, namely Thrace ("provincia Thracia") and Lower Moesia ("Moesia inferior"). Later, in the times of Diocletian, the two provinces were joined and formed the so-called "Dioecesis Thracia". The establishment of Roman colonies and mostly several Greek cities, as was Nicopolis, Topeiros, Traianoupolis, Plotinoupolis, and Hadrianoupolis resulted from the Roman Empire's urbanization. The Roman provincial policy in Thrace favored mainly not the Romanization but the Hellenization of the country, which had started as early as the Archaic period through the Greek colonisation and was completed by the end of Roman antiquity. As regards the competition between the Greek and Latin language, the very high rate of Greek inscriptions in Thrace extending south of Haemus Mountains proves the complete language Hellenization of this region. The boundaries between the Greek and Latin speaking Thrace are placed just above the northern foothills of Haemus Mountains.

During the imperial period many Thracians – particularly members of the local aristocracy of the cities – had been granted the right of the Roman citizenship (civitas Romana) with all its privileges. Epigraphic evidence show a large increase in such naturalizations in the times of Trajan and Hadrian, while in 212 AD the emperor Caracalla granted, with his well-known decree (constitutio Antoniniana), the Roman citizenship to all the free inhabitants of the Roman Empire. During the same period (in the 1st-2nd century AD), a remarkable presence of Thracians is testified by the inscriptions outside the borders (extra fines) both in the Greek territory and in all the Roman provinces, especially in the provinces of Eastern Roman Empire.

Medieval history
By the mid-5th century, as the Western Roman Empire began to crumble, Thracia fell from the authority of Rome and into the hands of Germanic tribal rulers. With the fall of the Western Roman Empire, Thracia turned into a battleground territory for the better part of the next 1,000 years. The surviving eastern portion of the Roman Empire in the Balkans, later known as the Byzantine Empire, retained control over Thrace until the 7th century when the northern half of the entire region was incorporated into the First Bulgarian Empire and the remainder was reorganized in the Thracian theme. The Empire regained the lost regions in the late 10th century until the Bulgarians regained control of the northern half at the end of the 12th century. Throughout the 13th century and the first half of the 14th century, the region was changing in the hands of the Bulgarian and the Byzantine Empire (excluding Constantinople). In 1265 the area suffered a Mongol raid from the Golden Horde, led by Nogai Khan, and between 1305 and 1307 was raided by the Catalan company.

Ottoman period
In 1352, the Ottoman Turks conducted their first incursion into the region subduing it completely within a matter of two decades and ruled it for five centuries in general peace. In 1821, several parts of Thrace, such as Lavara, Maroneia, Sozopolis, Aenos, Callipolis, and Samothraki rebelled during the Greek War of Independence.

Modern history
With the Congress of Berlin in 1878, Northern Thrace was incorporated into the semi-autonomous Ottoman province of Eastern Rumelia, which united with Bulgaria in 1885. The rest of Thrace was divided among Bulgaria, Turkey and Greece at the beginning of the 20th century, following the Balkan Wars, World War I and the Greco-Turkish War. In Summer 1934, up to 10,000 Jews were maltreated, bereaved, and then forced to quit the region (see 1934 Thrace pogroms). From Bulgaria and Romania between 1934 and 1938 a large wave of Muslims immigrants called Göçmenler went to East Thrace.

Today, Thracian is a geographical term used in Bulgaria, Turkey, and Greece.

Notable Thracians

 * Orpheus was, in Ancient Greek mythology, the chief representative of the art of song and playing the lyre.
 * Protagoras was a Greek philosopher from Abdera, Thrace (c. 490–420 BC.) An expert in rhetorics and subjects connected to virtue and political life, often regarded as the first sophist. He is known primarily for three claims: (1) that man is the measure of all things, often interpreted as a sort of moral relativism, (2) that he could make the "worse (or weaker) argument appear the better (or stronger)" (see Sophism), and (3) that one could not tell if the gods existed or not (see Agnosticism).
 * Herodicus was a Greek physician of the fifth century BC who is considered the founder of sports medicine. He is believed to have been one of Hippocrates' tutors.
 * Democritus was a Greek philosopher and mathematician from Abdera, Thrace (c. 460–370 BC.) His main contribution is the atomic theory, the belief that all matter is made up of various imperishable indivisible elements which he called atoms.
 * Spartacus was a Thracian who led a large slave uprising in what is now Italy in 73–71 BC. His army of escaped gladiators and slaves defeated several Roman legions in what is known as the Third Servile War.
 * A number of Roman emperors of the 3rd–5th century were of Thraco-Roman backgrounds (Maximinus Thrax, Licinius, Galerius, Aureolus, Leo the Thracian, etc.). These emperors were elevated via a military career (hence the resultant nickname for them, Barracks Emperor), from the condition of common soldiers in one of the Roman legions to the foremost positions of political power.
