According to Theophanes the Confessor, Constantine was then patrikios and logothetes tou dromou.[2][3] Constantine and his brother, who at the time was commander of the elite tagma of the Exkoubitores, were the leaders of the conspiracy which, according to Theophanes, included nineteen high-ranking officials in total, including several senior provincial governors (strategoi). After the plot's discovery, the conspirators were publicly paraded and humiliated at the Hippodrome of Constantinople on 25 August 766, following which Strategios and Constantine were beheaded at the Kynegion, while the others were blinded and exiled.[2][3] A few days later, the Eparch of the City Prokopios was also dismissed, followed by the deposition and exile of Patriarch Constantine II, after he was implicated by some clergymen in the conspiracy.[4]
