Empress Elisabeth of Austria was the mother of kings and saints. She was born in 1436 into a powerful but complicated Central European family, different members of which competed for various royal and imperial crowns during the mid-15th century. She was orphaned young, and then spent much of her childhood in different strongholds of the Holy Roman Empire in Austria. Her family was an attractive ally for European princes, and so in 1454, she was married to King Kazimierz IV of Poland (also known as Casimir IV). Despite her family connections, she was not an eager political player, but her familial role became crucial to the Polish monarchy and the Jagiellonian Dynasty. She died in 1515, with the Kingdom of Poland much stronger and better positioned in Central Europe than when she had become queen half a century earlier.

Elisabeth is renowned for what her children were able to achieve, and she played a strong role in their formation and advancement. She gave birth to 13 children, and 11 survived to become adults. As a deft manager of marriage diplomacy, she strategically arranged the marriages of several of her daughters, building or securing alliances of both prosperity and power. Even more impressively, though, four of her sons became kings. Władysław (Vladislav) became King of Bohemia and Hungary, and Jan Olbracht (John Alber), Aleksander (Alexander), and Zygmunt (Sigismund) all became King of Poland in succession. Meanwhile, Fryderyk (Frederick) became Archbishop of Gniezno, Primate of Poland, and Kazimierz (Casimir) became a contemporary saint in 1521. Her daughters Jadwiga, Zofia (Sophia), Anna, Barbara, and Elisabeth all married important princes of Central Europe.
