In 1894 Franz Ferdinand met Countess Sophie Chotek at a ball in Prague. To be eligible to marry a member of the Imperial House of Habsburg, one had to be a member of one of the reigning or formerly reigning dynasties of Europe. The Choteks were not one of these families, although they did include among their ancestors, in the female line, princes of Baden, Hohenzollern-Hechingen, and Liechtenstein. One of Sophie's direct ancestors was Albert IV, Count of Habsburg; she was descended from Elisabeth of Habsburg, a sister of King Rudolf I of Germany. Franz Ferdinand was a descendant of King Rudolf I. Sophie was a lady-in-waiting to Archduchess Isabella, wife of Archduke Friedrich, Duke of Teschen. Franz Ferdinand began to visit Archduke Friedrich's villa in Pressburg (now Bratislava). Sophie wrote to Franz Ferdinand during his convalescence from tuberculosis on the island of Lošinj in the Adriatic. They kept their relationship a secret.]
Deeply in love, Franz Ferdinand refused to consider marrying anyone else. Finally, in 1899, Emperor Franz Joseph agreed to permit Franz Ferdinand to marry Sophie, on condition that the marriage would be morganatic and that their descendants would not have succession rights to the throne. Sophie would not share her husband's rank, title, precedence, or privileges; as such, she would not normally appear in public beside him. She would not be allowed to ride in the royal carriage or sit in the royal box in theaters.
The wedding took place on 1 July 1900, at Reichstadt (now Zákupy) in Bohemia; Franz Joseph did not attend the affair, nor did any archduke including Franz Ferdinand's brothers. The only members of the imperial family who were present were Franz Ferdinand's stepmother, Princess Maria Theresa of Braganza, and her two daughters. Upon the marriage, Sophie was given the title "Princess of Hohenberg" (Fürstin von Hohenberg) with the style "Her Serene Highness" (Ihre Durchlaucht). In 1909, she was given the more senior title "Duchess of Hohenberg" (Herzogin von Hohenberg) with the style "Her Highness" (Ihre Hoheit). This raised her status considerably, but she still yielded precedence at court to all the archduchesses. Whenever a function required the couple to assemble with the other members of the imperial family, Sophie was forced to stand far down the line, separated from her husband.
Franz Ferdinand's children were:
Princess Sophie of Hohenberg (1901–1990), married Count Friedrich von Nostitz-Rieneck (1891–1973)
Maximilian, Duke of Hohenberg (1902–1962), married Countess Elisabeth von Waldburg zu Wolfegg und Waldsee (1904–1993)
Prince Ernst of Hohenberg (1904–1954), married Marie-Therese Wood (1910–1985)
Stillborn son (1908), buried in Artstetten Castle, near his parents
