Heiress-presumptive

When her elder sister Isabella II of Spain succeeded to the throne, Infanta Luisa Fernanda was heir presumptive to the crown between 1833 and 1851, when Isabella's oldest surviving daughter was born.

Marriage

Luisa Fernanda was engaged to the Duke of Montpensier, the youngest son of King Louis Philippe, who also was Luisa's mother's first cousin.

Luisa Fernanda, only 14 years old, and Antoine, 22, had their nuptials on 10 October 1846 as a double wedding with Isabella and Francis, and young Antoine was elevated to the rank of an Infante of Spain. The couple moved to Paris and later to Sevilla. The relationship between Isabella and her sister was tense, due to Antoine's conspiracies against the queen.^[1]

Antoine's father was deposed in 1848. The same year, the then 16-year-old Luisa Fernanda gave birth to their first child, Maria Isabel. After Isabella was deposed, the family went into exile. Luisa returned to Sevilla years later, already widowed, where she died.^[1] She is buried at Escorial.

The María Luisa Park was named after her.^[2]

Descendants

Of all her children, only Marie Isabelle and Antonio survived to adulthood. Through Antonio, the now non-royal line of dukes of Galliera continues. Alfonso's grandchildren lost royal status due to non-dynastic marriages. The current Duke of Galliera is Alfonso's great-grandson, Don Alfonso Francesco de Orléans-Borbón y Ferarra-Pignatelli.^[3]

Through Maria Isabel, she became great-grandmother of king Manuel II of Portugal, Amedeo, Duke of Aosta, Aimone, Duke of Spoleto, and Luis Filipe, Duke of Braganza; great-great-grandmother of Juan Carlos I of Spain and Henri, Count of Paris.
