History of Bulgaria
The Thracians
Evidence of human habitation in the area of Bulgaria dates from sometime within the Middle Paleolithic Period (Old Stone Age; 100,000 to 40,000 bce). Agricultural communities, though, appeared in the Neolithic Period (New Stone Age), and in the Bronze Age the lands were inhabited by Thracian tribes. The Thracians were eventually expelled or absorbed by Greek, Persian, and Roman colonies, but traces of their culture remain in their monuments devoted to horse worship and in the mummer (Bulgarian: kuker) tradition that still survives in southwestern Bulgaria.
In Roman times Bulgaria was divided between the provinces of Moesia (to the north of the Balkan Mountains) and Thrace (to the south of the Balkans) and was crossed by the main land route from the West to the Middle East. The ruins of Roman towns and settlements are numerous, and extensive sites have been excavated at Plovdiv in the southwest, Varna in the northeast, and other locations. Situated on the Black Sea, the ancient city of Nesebŭr, now a UNESCO World Heritage site, was the Thracian settlement of Mesembria for centuries before it became a Greek colony in the 6th century bce.
The beginnings of modern Bulgaria
Slavic invasions
The story of the modern Bulgarian people begins with the Slavic invasions of the Balkan Peninsula in the 6th and 7th centuries ce, a time when Byzantium was absorbed in prolonged conflict with Persia and could not resist the incursions from the north. Ancient sources refer to two Slavic tribes north of the Danube at this time, the Slavenae and the Antae. Evidence suggests that the Slavenae, to the west, were the ancestors of the Serbs and Croats, while the Antae moved into the regions of Bulgaria, Macedonia, and northern Greece. The Slavic tribes tilled the soil or practiced a pastoral way of life and were organized in patriarchal communities.
Arrival of the Bulgars
The name Bulgaria comes from the Bulgars, a people who are still a matter of academic dispute with respect to their origin (Turkic or Indo-European) as well as to their influence on the ethnic mixture and the language of present-day Bulgaria. They are first mentioned under this name in the sources toward the end of the 5th century ce. Living at that time on the steppes to the north of the Black Sea, the Bulgar tribes were composed of skilled, warlike horsemen governed by khans (chiefs) and boyars (nobles).
The Bulgars were subdued by the Avars in the 6th century, but in 635 Khan Kubrat led a successful revolt and organized an independent tribal confederation known as Great Bulgaria. After Kubrat’s death in 642, the Bulgars were attacked by the Khazars and dispersed. According to Byzantine sources, the Bulgars split into five groups, each under one of Kubrat’s sons. One of these sons, Asparukh (or Isperikh), moved into Bessarabia (between the Dniester and Prut rivers) and then crossed to the south of the Danube, where his people conquered or expelled the Slavic tribes living north of the Balkan Mountains. The Byzantine emperor Constantine IV led an army against the Bulgars but was defeated, and in 681 Byzantium recognized by treaty Bulgar control of the region between the Balkans and the Danube. This is considered to be the starting point of the Bulgarian state.
