谁嫁给了海伦娜·杜卡伊娜·安格利娜？

Helena Doukaina Angelina (Greek: Ἑλένη Δούκαινα Άγγελίνα, Helene Doukaina Angelina; Serbian: Jelena Duka Anđel) was a Greek noblewoman of Thessaly and Queen-consort of medieval Serbia.

Her parents were John I Doukas of Thessaly and his wife Hypomone (a daughter of the Thessalian Vlach chieftain Taronas). In ca. 1273/76, Helena married Serbian king Stefan Milutin (r. 1282–1321), but Milutin abandoned her in ca. 1283. It is possible that their sons were Kings Stefan Konstantin and Stefan Dečanski. It seems Helena then returned to Greece.

Stefan Uroš II Milutin (Serbian Cyrillic: Стефан Урош II Милутин, romanized: Stefan Uroš II Milutin; c. 1253 – 29 October 1321), known posthumously as "the Holy King" (Свети краљ), was the King of Serbia between 1282–1321, a member of the Nemanjić dynasty. He was one of the most powerful rulers of Serbia in the Middle Ages and one of the most prominent European monarchs of his time. Milutin is credited with strongly resisting the efforts of Byzantine Emperor Michael VIII Palaiologos to impose Roman Catholicism on the Balkans after the Union of Lyons in 1274. During his reign, Serbian economic power grew rapidly, mostly due to the development of mining. He founded Novo Brdo, which became an internationally important silver mining site. As most of the Nemanjić monarchs, he was proclaimed a saint by the Serbian Orthodox Church with a feast day on October 30.
