The Bulgarians are a South Slavic people native to Bulgaria and neighbouring regions. Emigration has resulted in immigrant communities in a number of other countries. The Bulgarians have descended from three main tribal groups, which mixed themselves and formed a Slavic-speaking nation and ethnicity in the First Bulgarian Empire: 1) the Slavs, who gave their language to the Bulgarians; 2) the Bulgars, from whom the ethnonym and the early statehood were inherited; as well as 3) the 'indigenous' late Roman provincial peoples: Thraco-Romans and Thraco-Byzantines, from whom certain cultural elements were taken. The ethnonym Bulgars is first attested by an anonymous Roman chronograph of 354 A.D. (Latin: Vulgares). Between the 7th and the 10th centuries, the local population, the Bulgars and the other tribes in the empire, which were outnumbered by the Slavs gradually became absorbed by them, adopting a South Slav language.
