Daurentius is the first Slavic chieftain to be recorded by name, by the Byzantine historian Menander Protector, who reported that the Avar khagan Bayan I sent an embassy, asking Daurentius and his Slavs to accept Avar suzerainty and pay tribute, because the Avars knew that the Slavs had amassed great wealth after repeatedly plundering the Byzantine Balkan provinces. Daurentius reportedly retorted that "Others do not conquer our land, we conquer theirs so it shall always be for us", and had the envoys slain.
