Ferdinand I (19 April 1793 – 29 June 1875) was the Emperor of Austria from 1835 until his abdication in 1848. As ruler of Austria, he was also President of the German Confederation, King of Hungary, Croatia and Bohemia (as Ferdinand V), King of Lombardy–Venetia and holder of many other lesser titles. Ferdinand succeeded on the death of his father Francis II and I on 2 March 1835. He was incapable of ruling his empire because of his mental deficiency, so his father, before he died, made a will which promulgated that Ferdinand should consult Archduke Louis on all aspects of internal policy and urged him to be influenced by Prince Metternich, Austria's Foreign Minister. Following the Revolutions of 1848, Ferdinand abdicated on 2 December 1848. He was succeeded by his nephew, Franz Joseph. Following his abdication, he lived in Hradčany Palace, Prague, until his death in 1875. Ferdinand married Maria Anna of Savoy, the sixth child of Victor Emmanuel I of Sardinia. They had no children.
