Her birth name was Fabia. She was betrothed to Heraclius when the future emperor still resided in the Exarchate. The Exarch at the time was her father-in-law Heraclius the Elder.
Heraclius had started a revolt against Phocas in 608. Under unknown circumstances both Fabia and her mother-in-law Epiphania seem to have been captured by Phocas by 610. They spent their captivity in the monastery "Nea Metanoia" (New Repentance) and were used as hostages to prevent Heraclius from besieging Constantinople. The two women were eventually released by members of the Green faction of Byzantine chariot racing events. They were delivered to Heraclius at the small island of Kalonymos in the Sea of Marmara, leaving him free to launch his successful assault. The Excubitors defected to his side and thus allowed him to enter the city without serious resistance.[citation needed] On 5 October 610, Heraclius was proclaimed Emperor and, on the same day, married Fabia. She took the name Eudokia and was granted the title of Augusta.[1]
