谁嫁给了Helena of Moscow？

Helena Ivanovna of Moscow (Russian: Елена Ивановна; Lithuanian: Elena Maskvietė; Polish: Helena Moskiewska; 19 May 1476 – 20 January 1513) was Grand Duchess of Lithuania and Queen of Poland as the consort of Alexander Jagiellon. She was a daughter of Ivan III, Grand Prince of Moscow, and she was never crowned as she would not convert from Eastern Orthodoxy to Catholicism. Her childless marriage to Alexander was a constant source of tension between the Grand Duchy of Moscow and the Grand Duchy of Lithuania. Instead of guaranteeing peace, Helena's marriage gave her father Ivan III an excuse to interfere in Lithuanian affairs accusing Alexander of mistreating Helena and repressing Orthodox believers. This became the pretext to renew the Muscovite–Lithuanian Wars in 1500. The war ended with a six-year truce in 1503; the Grand Duchy of Lithuania lost about a third of its territory. Despite political tensions and religious differences, the marriage was a loving one and the royal couple was close. After her husband's death in 1506, Helena wanted to return to Moscow but was not allowed. When she planned to run away, she was arrested and reportedly poisoned.

亞歷山大·雅盖隆契克（波蘭語：Aleksander Jagiellonczyk；立陶宛語：Aleksandras Jogailaitis）1461年8月5日—1506年8月19日，雅盖隆王朝的波蘭國王和立陶宛大公。

亞歷山大·雅盖隆契克为波兰国王卡齐米日四世的第四子，1492年在其父死後被選為立陶宛大公。在兄长揚一世·阿爾布雷赫特国王于1501年6月17日去世後，亞歷山大在当年12月12日繼位為波蘭國王。

其在獲選為大公當年，收到克里米亞可汗的譴責函，聲稱来自基輔和切爾卡瑟的大公的子民（哥薩克人，這是該稱謂於世界史第一次出現的記錄）掠奪了一艘韃靼人的船並俘虜了上面的人，地點可能是第聶伯河下游：時亞歷山大未有疑問是否屬實，而要求邊境地區（以「烏克蘭」稱之）官員追緝並處決可能參與者，並將被劫財物交還可汗的代表。

亞歷山大·雅盖隆契克未能有效阻止莫斯科大公伊凡三世对立陶宛的侵略，在1494年時就無奈地承認莫斯科統治者持有着「全羅斯」最高主宰等一系列的頭銜，因而失去了立陶宛大公國的一些重要領土，例如基輔附近的切爾尼戈夫。

亞歷山大繼位波蘭國王後的統治開啟了新紀元，放棄了卡齊米日四世的中央集權化改革，承認王公會議的權威性，承諾在任免重要官員時會先和會議成員協商，同時也與魯塞尼亞人（即烏克蘭人和白羅斯人）親王建立起密切關係。在其之後的立陶宛和波蘭的君主，都對莫斯科在東部的攻勢採取比卡齊米日四世更嚴肅以待的態度。
