Emperor Ferdinand I of Austria was a sovereign of Habsburg-Lorraine dynasty who reigned from 1835 until his abdication in 1848. Because he was the monarch of Austria, he was granted titles like president of the German Confederation, king of Hungary, Croatia and Bohemia (as Ferdinand V), and king of Lombardy–Venetia. As he had a coarse, unassertive but well-intentioned personality, he garnered the sobriquet The Benign or The Good. The eldest son of his parents, Ferdinand was born with multiple disorders, including epilepsy, hydrocephalus, and a speech impediment, likely due to the genetic proximities of his parents. He was tutored by Baron Josef Kalasanz von Erberg and his wife, Josephine. Following the death of his father, Francis II, in March 1835, Ferdinand ascended the throne. He could not perform his imperial duties due to his mental deficiencies. However, his father, prior to his death, had created a will in which he instructed Ferdinand to listen to the counsel of Archduke Louis and Prince Metternich. During his reign, the Regent’s Council also included Count Kolowrat. After the Revolution of 1848 took place, Ferdinand I abdicated in favour of his nephew Franz Joseph. He subsequently left Vienna and spent the remainder of his life in Hradčany Palace, Prague.
