Jelena Balšić

Jelena was born in 1411 as the daughter of Balša III of Zeta and Mara Thopia of Albania. She was named after her grandmother Jelena. Jelena's lineage is traced back to the Balšić and Thopia noble families. In 1424, at the age of 13, Jelena married Stjepan Vukčić Kosača, a significant political figure of the time. The union between Jelena and Stjepan Vukčić played a crucial role in shaping the political landscape of the region. Jelena was not only a wife and mother but also a central figure in the complex power dynamics of the time. Through her marriage to Stjepan Vukčić, she became the mother of several notable children, each leaving a mark on the history of the Balkans. Jelena died in 1453.
