Ferdinand I was Emperor of Austria, President of the German Confederation, King of Hungary (as Ferdinand V), and many others from the death of his father (Francis I, Emperor of Austria) on 2 March 1835, until his abdication after the Revolutions of 1848.
He married Maria Anna of Savoy, the sixth child of Victor Emmanuel I of Sardinia. They had no issue.
Ferdinand was incapable of ruling his empire because of his mental deficiency, so his father, before he died, drafted a will promulgating that he consult Archduke Louis on every aspect of internal policy, and urged him to be influenced by Prince Metternich, Austria's Foreign Minister.
He 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.
He used the titles:
His Imperial and Royal Apostolic Majesty Ferdinand the First, By the Grace of God
Emperor of Austria, King of Hungary, Bohemia, fifth by this name, King of the Lombardy and Venice, King of Dalmatia, Croatia, Slavonia, Galicia, Lodomeria, and Illyria;
