The Balkan–Danubian culture was an early medievalarchaeological culture which emerged in the region of the Lower Danube in the 8th century and flourished until the 11th century. In Romania it is called Dridu culture, while in Bulgaria it is usually referred to as Pliska-Preslav culture. It is better represented on the territory of modern-day Northern Bulgaria although its spread north of the Danube is also well attested due to the continuous extension of the First Bulgarian Empire over the territory of present-day Romania. The Balkan–Danubian culture is described as an early Slavic-Bulgarian culture, but besides Slavic and Bulgar elements it possesses also some Romance components, all of them under a Byzantine influence.
