Claim: Akameros was the "archon of the Sclavenes of Belzetia", mentioned only once by Theophanes the Confessor, and planned to overthrow Empress Irene of Athens.
Evidence: Akameros (Greek: Ἀκάμηρος, fl. 799 AD)—his original name was probably Akamir—was the "archon of the Sclavenes of Belzetia" (ό των Σκλαυινών της Βελζητίας άρχων), an autonomous South Slavic community in Central Greece under Byzantine sovereignty, in the late 8th century. He is mentioned only once, by Theophanes the Confessor, as leading a plot involving the sons of Constantine V (r. 741–775) – the former Caesares Nikephoros and Christopher, and their younger brothers Niketas, Anthimos and Eudokimos – who had been deposed, mutilated by their elder brother, the emperor Leo IV the Khazar (r. 775–780). After Leo's death, his wife, Irene of Athens (r. 797–802), deposed her son Constantine VI (r. 780–797) in 797, and sent his uncles in exile to Athens so that they would not threaten her rule. In March 799, Akameros, in collusion with troops from the local theme of Hellas, planned to seize them and declare one of them emperor.
