Maria Leopoldine's oldest brother, Ferdinand Charles, inherited Further Austria, but Dowager Archduchess Claudia assumed regency because of her son's minority. In a letter written to his mother, Elizabeth of England, on 8 September 1641, Charles Louis of the Palatinate (later Elector Palatine) described the intentions of his uncle, King Charles I of England, and Maria Leopoldine's first cousin, Ferdinand III, Holy Roman Emperor, to arrange a marriage between the 9-year-old archduchess and himself; the marriage between them was to end "all grudges betweene our families".[5] However, the union never took place.
In Linz on 2 July 1648 Maria Leopoldine married the widowed Holy Roman Emperor Ferdinand III, thereby becoming Empress of the Holy Roman Empire, Queen of the Germans, Queen of Hungary and Queen of Bohemia. The wedding ceremony was splendid.[6] The composer Andreas Rauch celebrated the marriage as "anticipating (with the help of Divine Providence) the most beautiful end of the Thirty Years' War"[7] and an opera titled I Trionfi d'Amore, produced by Giovanni Felice Sances, was meant to commemorate the event, but the Prague premiere was canceled at the last moment when King Władysław IV Vasa (Ferdinand III's brother-in-law) died within two months of the wedding; the planned Pressburg performance apparently never took place.[7] The new empress was as closely related to her husband as her cousin and predecessor, Maria Anna of Spain; both marriages were means by which the House of Habsburg frequently reinforced itself,[8] and ultimately succumbed to inbreeding.
Soon after her wedding, Maria Leopoldine became pregnant, and was depicted as such in the 1649 painting by the Italian painter and poet Lorenzo Lippi. The Imperial couple's only child, Archduke Charles Joseph of Austria, was born on 7 August 1649.[9] The childbirth was extremely difficult, ending in the death of the 17-year-old empress.[10] Her husband remarried within two years, while their son died childless aged 14.[2][7][11] She is buried in tomb 21 in the Imperial Crypt in Vienna. The writer Wolf Helmhardt, Baron von Hohberg, then at the beginning of his career, sent to Emperor Ferdinand III a poem written in honour of the late Empress, called "Poem of tears" (de: Klag-Gedicht).[12]
