Overview
Irene Doukaina or Ducaena (, Eirēnē Doukaina; – 19 February 1138) was a Byzantine empress by marriage to the Byzantine emperor Alexios I Komnenos. She was the mother of Emperor John II Komnenos and the historian Anna Komnene. She was initially heavily overshadowed and humiliated by her one in influence and powerful mother-in-law Anna Dalassene, but after her retirement and death, Irene was able to exert increasing influence over her husband Alexios I Komnenos, who she became powerful towards the end of his reign. But even so, she could not arrange his successor according to her wish, in favor of her daughter Anna Komnene and to the detriment of her son John II Komnenos.
Life
Irene was born in 1066 to Andronikos Doukas and Maria of Bulgaria, granddaughter of Ivan Vladislav of Bulgaria. Andronikos was a nephew of Emperor Constantine X Doukas and a cousin of Michael VII.
Succession of Alexios
Irene married Alexios in 1078, when she was still eleven years old. For this reason, the Doukas family supported Alexios in 1081, when a struggle for the throne erupted after the abdication of Nikephoros III Botaneiates. Alexios' mother, Anna Dalassene, a lifelong enemy of the Doukas family, pressured her son to divorce the young Irene and marry Maria of Alania, the former wife of both Michael VII and Nikephoros III. Irene was in fact barred from the coronation ceremony, but the Doukas family convinced the Patriarch of Constantinople, Kosmas I, to crown her as well, which he did one week later. Anna Dalassene consented to this but forced Kosmas to resign immediately afterwards; he was succeeded by Eustratios Garidas.
