The Bulgars (also Bulghars, Bulgari, Bolgars, Bolghars, Bolgari,[1] Proto-Bulgarians[2]) were Turkic semi-nomadic warrior tribes that flourished in the Pontic–Caspian steppe and the Volga region during the 7th century. They became known as nomadic equestrians in the Volga-Ural region, but some researchers say that their ethnic roots can be traced to Central Asia.[3] During their westward migration across the Eurasian steppe, the Bulgar tribes absorbed other ethnic groups and cultural influences in a process of ethnogenesis, including Indo-European, Finno-Ugric and Hunnic tribes.[4][5][6][7][8][9] Modern genetic research on Central Asian Turkic people and ethnic groups related to the Bulgars points to an affiliation with Western Eurasian populations.[9][10][11] The Bulgars spoke a Turkic language, i.e. Bulgar language of Oghuric branch.[12] They preserved the military titles, organization and customs of Eurasian steppes,[13] as well as pagan shamanism and belief in the sky deity Tangra.[14]
The exact ethnic origins of the Danubian Bulgars is controversial. It is in any case most probable that they had enveloped groupings of diverse origins during their migration westwards across the Eurasian steppes, and they undoubtedly spoke a form of Turkic as their main language. The Bulgars long retained many of the customs, military tactics, titles and emblems of a nomadic people of the steppes.
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.[permanent dead link]
Although many scholars, including linguists, had posited that the Bulgars were derived from a Turkic tribe of Central Asia (perhaps with Iranian elements), modern genetic research points to an affiliation with western Eurasian populations.
