František Ferdinand d'Este was the Austrian, Hungarian, and Czech crown prince. He was born December 8, 1863, in Graz. In 1896 he officially succeeded Crown Prince Rudolf to the Habsburg throne. In Prague, he met the young Countess Žofia Chotková from Chotkov and Vojín, a member of an old Czech aristocratic family. Their marriage in 1900 was ancestral, unequal, and frowned upon by Emperor Francis Joseph I.
