Eastern Europe





Present day Bulgaria was formed as a tribal area from the late seventh century AD onwards. Prior to that, throughout much of antiquity, large swathes of southern Bulgaria traditionally formed the territory of ancient Thrace, while the rest was occupied by a large number of barbarian tribes, including the Dacians and Celtic Scordisci.

MapProto-Bulgarians settled in the area of the Caucuses, north and east of the Black Sea, in the fourth to fifth centuries where they were dominated by the Goths. Some early Bulgar elements may have been forced westwards from their earlier homeland by the expansionist conquests of the Göktürks in the sixth century. Once resettled they mixed with Slavic groups which arrived in the same century. By the early seventh century, the Bulgarians had set up a powerful tribal amalgamation known as Great Bulgaria. Its ruler was Khan Koubrat, who established friendly relations with the Byzantine empire, but after his death the state crumbled under pressure from the Khazars.

Some Bulgarians remained in the area and were subdued by the Khazars, but others travelled, reaching the Volga where they set up Volgan Bulgaria with its capital at Kazan. This existed up until the thirteenth century when it was wiped out by Tartars. Another group of proto-Bulgarians, lead by Kouber, settled first in Pannonia, and subsequently in the region of Bitolya (Macedonia).

c.150 - 200

Far from remaining settled where they are in Poland, the Goths gradually renew their migration, now shifting slowly southwards from the Oder and Vistula, heading on a path that will eventually take them into Ukraine and the northern Black Sea coastline, an area known to the ancients as Scythia. Jordanes states that they first migrate to Lake Maeotis (the modern Sea of Azov, at the north-eastern corner of the Black Sea). Then a second migration takes them westwards along the northern Black Sea coast into Moesia (on the southern bank of the Danube), Thrace (to the south of Moesia), and Dacia (north of the Danube). A third migration takes them back into Scythia.

The initial migration could be caused by pressure from the Baltic tribes, early segments of the later Lithuanians, who are expanding back into territory they had lost to the Germanic tribes in the first century AD. The later bouncing around between Lake Maeotis and the Danube is less easy to explain, unless the proto-Bulgars who dwell close by Maeotis manage to expel them. Then they are pushed back from the west (possibly by the Romans in their Danubian campaigns in this century), before they finally decide to take control of the northern Black Sea coast. They soon dominate the proto-Bulgars on their eastern flank.

Great Bulgaria
AD c.632 - 668

Great Bulgaria incorporated a large mix of peoples in its rather uncertain borders. This mix probably included the various survivors of the Huns, the Altyn Ola Horde, and the Kutrigur and Utigur Bulgars (although the latter were not necessary ethnic Bulgarians). This does not mean that they became part of the later Bulgarian state, of course, which was a much smaller entity than Great Bulgaria. Instead they probably dissipated into the surrounding population in Ukraine, on either side of the Don. However, the notion that Hun descendants may enter the Bulgarian gene pool seems to be highly controversial and open to strong objections. If it happens at all, the number of actual Huns rather than their many subject peoples who are not of Hunnish descent is likely to be a minute part of the population.

c.632 - c.651

Khan or Qaghan Kubrat / Koubrat

FeatureCreated the Great Bulgarian state.

c.632 - c.651

Khan Kubrat is the first to lay the foundations of Bulgar military and tribal alliance and forms a capital at Phanagoria on the Taman Peninsula. By this time the Altyn Ola Horde has been absorbed, along with the Kutrigur and Utigur Bulgars. Kubrat makes peace with the Byzantine empire and is awarded the title of patrician by Heraclius. Kubrat dies some time after 651 and Great Bulgaria gradually falls apart.

c.651 - 668

Bat Bayan

Eldest son.

652 - 653

The growing Islamic empire begins to threaten Armenia. Aided by the Byzantines, Armenia defends itself, but the Arab campaign continues northwards into the Caucuses under General Salman. He concentrates on the towns and settlements of the western coast of the Caspian Sea and on defeating the Khazars. A description of this campaign is based on a manuscript by Ahmed-bin-Azami, and it mentions that '...Salman reached the Khazar town of Burgur... He continued and finally reached Bilkhar, which was not a Khazar possession, and camped with his army near that town, on rich meadows intersected by a large river'.

This is why several historians connect the town with the proto-Bulgarians. The Arab missionary Ahmed ibn-Fadlan also confirms this connection, as he mentions that during his trip to the Volga Bulgars in 922 he sees a group of 5,000 Barandzhars (balandzhars) who had migrated a long time ago to Volga Bulgaria.

The Caspian Sea around Dagestan
Could at least one group of peoples who lived close to seventh century Dagestan and the western shores of the Caspian Sea have been Venedi who had been dragged there by the returning Huns and their other associates?

According to Ibn al-Nasira, after capturing Belendzher-Bulker, Salman reaches another large town, called Vabandar, which has 40,000 houses (families?). M I Artamonov links the name of that town with the ethnicon of the Unogundur Bulgars, which is given as 'v-n-nt-r' by the Khazars (in the letter by their Khagan Joseph). It is shown as 'venender' or 'nender' by the Arabs, and as Unogundur-Onogur by the Byzantines. Variations of 'v-n-nt-r' appear in 668, 982 and 1094, and all suggest that elements of the Venedi have been pinpoined without the authors really knowing their identity.

Interpreting the documentary evidence, Artamonov concludes that the early medieval population of Northern Dagestan consists of proto-Bulgarian tribes, so that mentions by several authors of a kingdom of the Huns and their country should rather be called a kingdom of the Bulgars. He also regards as proto-Bulgarian 'the magnificent town of Varachan', the main centre of the Huns, which is located by Moses Kagantvaci to the north of Derbend.


The Fredegarii Chronicon records that in Pannonia (part of which now forms Khorushka's territory), a dispute arises between the Avars and a large, migrant population of around nine thousand Bulgars. Under the leadership of a Prince Alcioka, the Bulgars seek help from the Bavarii but are almost entirely slaughtered on the orders of the Frankish King Dagobert of Austrasia. Something like seven hundred survivors enter the marca Vinedorum, the land of the Slavs, and meet its ruler, one Duke Valuk ('Wallucum ducem Vinedorum', possibly linked to the Slav Kingdom).


Great Bulgaria disintegrates following a massive Khazar attack during their period of expansion in the second half of the seventh century. Bat Bayan and his brothers part company, each leading their own followers. Bat Bayan remains in his native land and is soon subdued by the Khazars. The second son, Kotrag, founds a state in the confluence of the Volga and the Kam, known as Volga Bulgaria (or the Volga Bulgars), which survives until the beginning of the thirteenth century. These Bulgars appear to have an influence on the language of the Magyars who later form Hungary. In fact, the Chuvash language, an extraordinary Turkish dialect that is now spoken in the Middle-Volga region, is thought to be the continuation of the language of the Volga Bulgars, revealing a degree of influence by them on the Magyars.

Kuber leads part of the Bulgars to Pannonia and settles in Macedonia. Altsek and his group of Bulgars reach Italy. The youngest, Asparukh, leads between 30,000 to 50,000 people westwards from the Ergeni Hills (the Hippian Mountains) in northern present-day Kalmykia (in Russia), towards the northern coast of the Black Sea. They soon reach the Danube and found a new kingdom of Bulgaria.

A number of other tribal names have been associated with that of the Bulgars. Some medieval documents mention that Asparukh also leads a people named 'v.n.n.tr' (in Khazar sources) or 'Unogundur' (in Byzantine sources). This ethnonym has been related by historians to the names 'Venender', 'Vhndur', and 'Onogur' that appear in other texts. This name in its Khazar form is very similar to references to the same people in 982 and 1094 - strongly suggesting that they are the Venedi, Eastern Celts who may, if they are migrating with Asparukh, have ventured far further east than has previously been suspected. Also, the tribes of the Utigurs and Kutrigurs which appear in some narrative sources referring to the sixth century are associated by many historians with the Bulgars.

Kingdom of Bulgaria
c.AD 681 - 889

The kingdom was formed by a third group of proto-Bulgarians (the first group forming the core of Great Bulgaria and the second reaching the Volga). These Bulgarians were led by the tribal chieftain Asparouh, who headed for the west and reached the Danube at the beginning of the last quarter of the seventh century. There, his people founded an independent kingdom that conquered territory from the Byzantine empire while it was fighting the Arabs in the east and south. They probably also conquered local tribes that had been settled there for two or three centuries, such as the Bastarnae, remnants of the Goths, and the Huns.

The rulers were known as khans, in the Asiatic tradition, and remained independent of Byzantium until 971. There is some archaeological evidence to suggest an element of continuity between this peoples and the Huns who had previously conquered the region. The most characteristic weapon of both peoples, their long bows, are almost identical.

The Battle of Nicopolis results in defeat for the allied European forces. Amongst the participants is Duke Charles II of Lorraine and Count John the Fearless of Nevers. The Bulgars are conquered and occupied by the Ottoman Turks.

1828 - 1829

The Russo-Turkish War, triggered by the fighting in Greece and the Danubian principalities, ends in the Peace of Adrianople. The Ottoman sultan closes the Dardanelles to Russian vessels but the Russians lay siege to three major Ottoman cities in Bulgaria. In the end, despite an embarrassing defeat along the way, Russia wins the mouth of the Danube and much of the Black Sea's western coast under the terms of the peace, or Treaty of Adrianople. Serbia also achieves autonomy.


After the Russo-Turkish War, the Principality of Bulgaria is set up which includes Moesia and the Sofia region, but not southern Bulgaria (East Rumelia) or the Macedonian region. A German prince is elected as head of state.

The First Balkan War brings Greek victory in the capture and permanent possession of Salonika (modern Thessaloniki - the second largest city in Greece), just beating a Bulgarian force which had also aimed at capturing it. Following the Second Balkan War, Bulgaria's Southern Dobruja region is annexed to Rumania, giving it territory to the south of the lower Danube.


Despite being courted by the Allies, especially Britain and France, Bulgaria has noted the failures of the Gallipoli campaign against Turkey and the Italian campaign against Austria-Hungary and signs four treaties with Germany and Austria on 6 September, agreeing to attack Serbia in return for territory.

Modern Bulgaria
AD 1946 - Present Day

Modern Bulgaria was occupied by Soviet forces at the end of the Second World War and the monarchy was abolished. Bulgaria has a long Black Sea coast and is a predominantly Slavic-speaking country.

In the ancient world, areas of central and eastern Bulgaria formed parts of the kingdom of Thrace, as well as various Thracian tribal areas outside this. Other areas were occupied by a large number of barbarian tribes, such as the Dacians and Celtic Scordisci.

1946 - 1993
