Irene Doukaina
Irene Doukaina (Greek: Εἰρήνη Δούκαινα; c. 1066 – 19 February 1133) was a Byzantine noblewoman and empress consort, married to Emperor Alexios I Komnenos from 1078 until his death in 1118.[1][2] Daughter of the general Andronikos Doukas and Maria of Bulgaria, her union with Alexios forged a key alliance with the powerful Doukas family, aiding his seizure of the throne in 1081.[2] As empress, she bore nine children, among them the future emperor John II Komnenos and the chronicler Anna Komnene, whose Alexiad provides primary insights into her character and influence.[1] Irene exerted significant political sway, initially favoring the succession of her daughter Anna and son-in-law Nikephoros Bryennios, though she ultimately supported John II against their coup attempt following Alexios's death.[3] After taking monastic vows as Euphrosyne, she founded the Kecharitomene Monastery in Constantinople, exemplifying her patronage of religious institutions that blended personal piety with imperial authority.[2]
