Franz Joseph I of Austria
Relationship with Franz Ferdinand

Archduke Franz Ferdinand became heir presumptive (Thronfolger) to the throne of Austria-Hungary in 1896, after the deaths of his cousin Rudolf (in 1889) and his father Karl Ludwig (in 1896). The relationship between him and Franz Joseph had always been a fairly contentious one, which was further exacerbated when Franz Ferdinand announced his desire to marry Countess Sophie Chotek. The emperor would not even consider giving his blessing to the union, as Sophie was merely of noble rank, not dynastic rank.

Although the emperor received letters from members of the imperial family throughout the fall and winter of 1899 beseeching him to relent, Franz Joseph stood his ground. He finally gave his consent in 1900. However, the marriage was to be morganatic, and any children of the marriage would be ineligible to succeed to the throne. The couple were married on 1 July 1900 at Reichstadt. The emperor did not attend the wedding, nor did any of the archdukes. After that, the two men disliked and mistrusted each other.

His interactions with Franz Ferdinand were strained; the emperor's personal attendant recollected in his memoirs that: "thunder and lightning always raged when they had their discussions."

Following the assassination of Franz Ferdinand and Sophie in 1914, Franz Joseph's daughter, Marie Valerie, noted that her father expressed his greater confidence in the new heir presumptive, his grandnephew Archduke Charles. The emperor admitted to his daughter, regarding the assassination: "For me, it is a relief from a great worry."
