谁嫁给了Irene Doukaina？

Irene Doukaina or Ducaena (Greek: Εἰρήνη Δούκαινα, Eirēnē Doúkaina; c. 1066 – 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 in influence and power by her mother-in-law Anna Dalassene, but after her retirement and death, Irene was able to exert increasing influence over her husband Alexios I Komnenos, and became powerful towards the end of his reign. But even so, she could not arrange his successor according to her wishes, which favoured her daughter Anna Komnene over her son John II Komnenos.

阿莱克修斯一世（希腊语：Αλέξιος Α' Κομνηνός，1048年或1056年—1118年8月15日）作为拜占庭皇帝，尽管他不是第一位科穆宁皇帝，但他是实际上的科穆宁王朝开创者。因为他统治期间，其家族真正达到拜占庭帝国的权力巅峰。阿莱克修斯率兵废黜尼基弗鲁斯三世，恢复科穆宁家族由于伊萨克一世退位而中断的统治，从而继承一个崩溃帝国，并面对帝国与小亚细亚的突厥人和巴尔干半岛以西诺曼人的持续战争。阿莱克修斯成功阻止帝国的衰弱并复兴军队，最终他与他后代的成就被称作“科穆宁中兴”。同時，他向西方求援以反击突厥人的举动，也成为引发十字军东征的缘由之一。
