Profile Ferdinand I, Brother of Charles V
Ferdinand was born in Alcalá de Henares, Spain, the son of Queen Joanna I of Castile from the House of Trastámara, who was the daughter of the Catholic Monarchs Isabel I of Castile and Ferdinand of Aragon, and Habsburg Archduke Philip the Handsome, who was heir to Maximilian I, Holy Roman Emperor.
Ferdinand shared his customs, culture, and even his birthday with his maternal grandfather Ferdinand II of Aragon. He was born, brought up, and educated in Spain. He did not learn German until he was older.
In the summer of 1518 Ferdinand was sent to Flanders following his brother Charles's arrival in Spain as newly appointed King Charles I the previous autumn.
When his grandfather Maximilian I died and his older nineteen-year-old brother, Charles V, acceded to the title of Holy Roman Emperor in 1519, Ferdinand was assumed the governance of the Austrian hereditary lands, broadly the lands of modern-day Austria and Slovenia.
He was Archduke of Austria from 1521 to 1564. Though he supported his brother, Ferdinand also managed to strengthen his own realm. By adopting the German language and culture late in his life, he also grew close to the German territorial princes.
After the death of his brother-in-law Louis II, Ferdinand ruled as King of Bohemia and Hungary. Ferdinand also served as Charles’s deputy in the Holy Roman Empire during his brother's many absences, and in 1531 was elected King of the Romans, making him Charles's designated heir in the empire.
Charles abdicated in 1556 and Ferdinand adopted the title "Emperor elect" in 1558, while Spain, the Spanish Empire, Naples, Sicily, Milan, the Netherlands, and Franche-Comté went to Philip, son of Charles.
