Archduke Franz Ferdinand Carl Ludwig Joseph Maria of Austria (Francis Ferdinand, 18 December 1863 – 28 June 1914) was the heir presumptive to the throne of Austria-Hungary. His assassination in Sarajevo was the most immediate cause of World War I.
Franz Ferdinand was the eldest son of Archduke Karl Ludwig of Austria, the younger brother of Emperor Franz Joseph I of Austria. Following the death of Crown Prince Rudolf in 1889 and the death of Karl Ludwig in 1896, Franz Ferdinand became the heir presumptive to the Austro-Hungarian throne. His courtship of Sophie Chotek, a lady-in-waiting, caused conflict within the imperial household, and their morganatic marriage in 1900 was only allowed after he renounced his descendants' rights to the throne. Franz Ferdinand held significant influence over the military, and in 1913, he was appointed inspector general of the Austro-Hungarian Armed Forces.
On 28 June 1914, Franz Ferdinand and his wife were assassinated in Sarajevo by the 19-year-old Gavrilo Princip, a member of Young Bosnia. Franz Ferdinand's assassination led to the July Crisis and precipitated Austria-Hungary's declaration of war against Serbia, which in turn triggered a series of events that eventually led – four weeks after his death – to Austria-Hungary's allies and Serbia's allies declaring war on each other, starting World War I.
Franz Ferdinand was born in Graz, then part of the Austrian Empire, the eldest son of Archduke Karl Ludwig of Austria (the younger brother of Franz Joseph and Maximilian) and of his second wife, Princess Maria Annunziata of Bourbon-Two Sicilies. In 1875, when he was eleven years old, his cousin Francis V, Duke of Modena, died, naming Franz Ferdinand his heir on condition that he add the name "Este" to his own. This inheritance made Franz Ferdinand one of the wealthiest men in Austria.
In 1889, Ferdinand's cousin Crown Prince Rudolf committed suicide at his hunting lodge in Mayerling. This left Franz Ferdinand's father, Karl Ludwig, first in line to the throne. When Karl Ludwig died of typhoid fever in 1896, Franz Ferdinand became the heir presumptive to the Austro-Hungarian throne.
Despite this burden, he found time for travel and personal pursuits, such as his circumnavigation of the world between 1892 and 1893. After visiting India he spent time hunting kangaroos and emus in Australia in 1893, then travelled on to Nouméa, New Hebrides, Solomon Islands, New Guinea, Sarawak, Hong Kong and Japan. After sailing across the Pacific on the RMS Empress of China from Yokohama to Vancouver he crossed the United States, arriving at the World's Columbian Exposition 1893 on the Chicago, Burlington, and Quincy Railroad on a private Pullman car named Mascotte, and staying at the Lexington Hotel, before continuing through to New York and returning to Europe.
Franz Ferdinand had a fondness for trophy hunting that was excessive even by the standards of European nobility in his day. In his diaries he kept track of 272,511 game kills, 5,000 of which were deer. About 100,000 trophies were on exhibit at his Bohemian castle at Konopiště which he also stuffed with various antiquities, his other great passion.
Franz Ferdinand, like most males in the ruling Habsburg line, entered the Austro-Hungarian Army at a young age. He was frequently and rapidly promoted, given the rank of lieutenant at age fourteen, captain at twenty-two, colonel at twenty-seven, and major general at thirty-one. While never receiving formal staff training, he was considered eligible for command and at one point briefly led the primarily Hungarian 9th Hussar Regiment. In 1898 he was given a commission "at the special disposition of His Majesty" to make inquiries into all aspects of the military services and military agencies were commanded to share their papers with him.
He also held honorary ranks in the Austro-Hungarian Navy, and received the rank of admiral at the close of the Austro-Hungarian naval maneuvers in September 1902.
Franz Ferdinand exerted influence on the armed forces even when he did not hold a specific command through a military chancery that produced and received documents and papers on military affairs. This was headed by Alexander Brosch von Aarenau and eventually employed a staff of sixteen. His authority was reinforced in 1907 when he secured the retirement of the Emperor's confidant Friedrich von Beck-Rzikowsky as Chief of the General Staff. Beck's successor, Franz Conrad von Hötzendorf, was personally selected by Franz Ferdinand.
Franz in 1913, as heir-presumptive to the elderly emperor, had been appointed inspector general of all the armed forces of Austria-Hungary (Generalinspektor der gesamten bewaffneten Macht), a position superior to that previously held by Archduke Albrecht and including presumed command in wartime.
In 1894, Franz Ferdinand met Countess Sophie Chotek, a lady-in-waiting to Archduchess Isabella, wife of Archduke Friedrich, Duke of Teschen. Franz began to visit Archduke Friedrich's villa in Pressburg (now Bratislava), and in turn Sophie wrote to Franz Ferdinand during his convalescence from tuberculosis on the island of Lošinj in the Adriatic. They kept their relationship a secret, until it was discovered by Isabella.
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. 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, provided 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, nor would she 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 ceremony, nor did Franz Ferdinand's brothers or any other archduke. The only members of the imperial family 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 was still required to yield precedence at court to all the archduchesses. Whenever a function required the couple to assemble with the other members of the imperial family, Sophie had 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)
