Relations of Martina and her stepson were always difficult. When Constantine III died suddenly of tuberculosis only four months later, the common belief was that the empress poisoned him to leave Heraklonas as sole ruler. However historians like Herren and Garland have stated that this is most likely not true. Martina began immediately to exile the prominent supporters of Constantine and with the help of Patriarch Pyrrhus I of Constantinople, one of her primary advisors, revived the policy of monothelitism. She recalled Bishop Cyrus of Alexandria and sent him to Egypt after his exile, showing her dedication to the policy of monothelitism.
