Константин VIII
Zoë was born when her father Constantine was nominal co-emperor to his brother, Basil II. Basil died in 1025 when Zoë was 47. Her father ascended the Byzantine throne as Constantine VIII. As he had no sons, Constantine hoped to continue the dynasty by marrying off one of his daughters. Zoë, aged 50, was married to Romanos Argyros. They took the throne the next day on her father's death.
