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.
