The mesazon (Greek: μεσάζων, romanized: mesazōn, lit. 'intermediary') was a high dignitary and official during the last centuries of the Byzantine Empire, who acted as the chief minister and principal aide of the Byzantine emperor. In the West, the dignity was understood as being that of the imperial chancellor (Latin: cancellarius imperii).[1]
