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.
