谁嫁给了João Manuel, Prince of Portugal？

Dom João Manuel, Hereditary Prince of Portugal (Portuguese pronunciation: [ʒuˈɐ̃w mɐnuˈɛl]) (3 June 1537 – 2 January 1554) was a Portuguese infante (prince), the eighth child of King John III of Portugal by his wife Catherine of Austria, daughter of Philip I of Castile and Joanna of Castile. As the heir to the throne he was styled Prince of Portugal.

Joanna of Austria (Spanish: Doña Juana de Austria; in Portuguese, Dona Joana de Áustria; 24 June 1535 – 7 September 1573) was an Infanta of Spain by birth and Princess of Portugal by marriage to João Manuel, Prince of Portugal. She served as regent of Spain for her brother Philip II during his trips to England to marry Mary I from 1554 to 1556, and 1556 to 1559. She was the mother of King Sebastian of Portugal.

Married at 16 to her even younger husband, Joanna was widowed after two years, giving birth in the same month to her only child. Later that year Joanna returned to Spain at her father's request, leaving her young son in the care of her mother-in-law, who was also her aunt. She never saw Sebastian again, but corresponded and had portraits sent. In later life Joanna was active in religious affairs.
