List of Roman Augustae and Empresses

This is a list of women who were Roman or Byzantine empresses, i.e. the wives of Roman Emperors, and Augustae, i.e. the most senior ranking women at court. 
The Byzantine Empire produced at least three empresses regnant: Irene of Athens, Zoe the Macedonian and Theodora. Sometimes Theodora, consort to Justinian I, and Eudoxia Laskarina, consort to Romanos VI Melissenos, are considered empresses in their own right. There was never an emperor consort, however; upon marriage, the husband assumed the full role and powers of an emperor regnant. 
The Byzantine empress (Basilissa) and the Byzantine Augusta (Augousta) were two distinct titles, which could be held by the same woman. The former was always held by the wife of an emperor in perpetuity. The latter was a given and revokable office, and also a hierarchically superior title as the head lady of the imperial court. Augustae were often empresses consorts, but there were notable exceptions. The most recent example was Irene of Bohemia, empress consort to Romanos V Melissenos, who was outranked by the Augusta Dowager Empress Theodora Megali Komnena and the otherwise more junior co-empress consort Eudoxia Laskarina, who also held the title of Augusta.
This is a list of all Roman and Byzantine empresses and Augustae after the point of divergence in the Arthurverse. For a complete list of the previous rulers, Wikipedia is recommended.
