Chatzon

Chatzon (Greek:Χάτζων) or, in some modern Slavic studies, Hacon (Хакон), was a Slavic chieftain (έξαρχος Σκλαβίνων, "exarch of the Sclaveni" in the Greek sources) who, according to Book II of the Miracles of Saint Demetrius, led a coalition of Slavic tribes to attack the Byzantine city of Thessalonica in 615.
