Joanna or Joan (also known as Joanna the Mad or Joan the Mad; ; 6 November 1479 – 12 April 1555) was Queen of Castile from 1504 and Queen of Aragon from 1516 to her death in 1555. She was the daughter of Queen Isabella I of Castile and King Ferdinand II of Aragon. Joanna was married by arrangement to the Austrian archduke Philip the Handsome on 20 October 1496.Bethany Aram, Juana the Mad: Sovereignty and Dynasty in Renaissance Europe (Baltimore, Johns Hopkins UP, 2005), p. 37 Following the deaths of her elder brother John, elder sister Isabella, and nephew Miguel between 1497 and 1500, Joanna became the heir presumptive to the crowns of Castile and Aragon. When her mother died in 1504, she became queen of Castile. Her father proclaimed himself governor and administrator of Castile.Bergenroth, G A, Introduction.

In 1506, Joanna's husband Philip became King of Castile jure uxoris as Philip I, initiating the rule of the Habsburgs in the Spanish kingdoms. Philip died that same year. Despite being the ruling Queen of Castile, Joanna had little effect on national policy during her reign as she was declared insane and confined in the Royal Palace in Tordesillas under the orders of her father, who ruled as regent until his death in 1516, when she inherited his kingdom as well. Her son Charles I became king, and during his reign, Joanna was nominally co-monarch but remained confined until her death. She died aged 75 in 1555. Historians have debated the authenticity of her alleged madness, and whether or not it was used to discredit her.

Early life

Joanna was born on 6 November 1479 in the city of Toledo in the Kingdom of Castile. She was the fourth but third surviving child and the second daughter of Isabella I of Castile and Ferdinand II of Aragon, both members of the House of Trastámara.

She had a fair complexion and brown eyes, and her hair colour was between strawberry-blonde and auburn, like her mother and her sister Catherine. Her siblings were Isabella, Queen of Portugal; John, Prince of Asturias; Maria, Queen of Portugal; and Catherine, Queen of England.Catherine was the first wife of Henry VIII and the mother of Mary I of England.

Education Joanna was educated and formally trained for a significant marriage that, as a royal family alliance, would extend the kingdom's power and security as well as its influence and peaceful relations with other ruling powers. As an Infanta (princess), she was not expected to be heiress to the throne of either Castile or Aragon, although through deaths she later inherited both thrones.

Joanna's academic education consisted of astromony, canon and civil law, genealogy and heraldry, geography, grammar, history, languages, mathematics, philosophy, reading, spelling and writing. Among the authors of classical literature she read were the Christian poets Juvencus and Prudentius, Church fathers Saint Ambrose, Saint Augustine, Saint Gregory, and Saint Jerome, and the Roman statesman Seneca.

In the Castilian court Joanna's main tutors were the Dominican priest Andrés de Miranda; educator Beatriz Galindo, who was a member of the queen's court; and her mother, the queen. Joanna's royal education included baking, chess, cooking, court etiquette, dancing, drawing, equestrian skills, good manners, music, the needle arts of embroidery, lace-making, needlepoint, sewing, spinning, and weaving, and singing . She studied the Iberian Romance languages of Castilian, Leonese, Galician-Portuguese and Catalan, and became fluent in French and Latin. She learned outdoor pursuits such as hawking and hunting. She was skilled at dancing and music; she played the clavichord, the guitar, the lute, and the monochord.

Marriage

In 1496, 16-year-old Joanna was betrothed to 18-year-old Philip of Austria, in the Low Countries. Philip's parents were Maximilian I, Holy Roman Emperor, and his first wife, Duchess Mary of Burgundy. The marriage was one of a set of family alliances between the Habsburgs and the Trastámaras designed to strengthen both against growing French power.

Joanna entered a proxy marriage at the Palacio de los Vivero in the city of Valladolid, Castile, where her parents had secretly married in 1469. In August 1496 Joanna left from the port of Laredo in northern Castile on the Atlantic's Bay of Biscay. Except for 1506, when she saw her younger sister Catherine, the then-Dowager Princess of Wales, she would never see her siblings again.

Joanna began her journey to Brabant in the Low Countries, which consisted of parts of the present day Netherlands, Belgium, Luxembourg, France, and Germany, on 22 August 1496. The formal marriage took place on 20 October 1496 in Lier, north of present-day Brussels. Between 1498 and 1507, she gave birth to six children, two boys and four girls, all of whom grew up to be either emperors or queens.Eleanor of Austria, Queen of France and Portugal, Charles V, Holy Roman Emperor, Isabella of Austria, Queen of Denmark, Ferdinand I, Holy Roman Emperor, Mary, Queen of Hungary, and Catherine of Austria, Queen of Portugal.

Princess of Asturias The death of Joanna's brother John, the stillbirth of John's daughter, and the deaths of Joanna's older sister Isabella and Isabella's son Miguel made Joanna heiress to the Spanish kingdoms. Her remaining siblings were Maria (1482–1517) and Catherine (1485–1536), younger than Joanna by three and six years respectively.

In 1502, the Castilian Cortes of ToroFrancisco Olmos, Estudio documental de la moneda castellana de Juana la Loca fabricada recognised Joanna as heiress to the Castilian throne and Philip as her consort. She was named Princess of Asturias, the title traditionally given to the heir of Castile.Aram, Bethany. (1998) "Juana 'the Mad's' Signature: The Problem of Invoking Royal Authority, 1505–1507" Sixteenth Century Journal, 29(2), 331–358. Also in 1502, the Aragonese Cortes gathered in Zaragoza to swear an oath to Joanna as heiress; however, the Archbishop of Zaragoza, Alonso de Aragón expressed firmly that this oath could only establish jurisprudence by way of a formal agreement on the succession between the Cortes and the king.Francisco Olmos, Estudio documental de la moneda castellana de Carlos I

In 1502, Philip, Joanna and a large part of their court traveled to Toledo for Joanna to receive fealty from the Cortes of Castile as Princess of Asturias, heiress to the Castilian throne, a journey chronicled in great detail by Antoon I van Lalaing (). Philip and the majority of the court returned to the Low Countries in the following year, leaving a pregnant Joanna in Madrid, where she gave birth to her fourth child, Ferdinand, later a central European monarch and Holy Roman Emperor as Ferdinand I.

Reign Queen of Castile

Succession Upon the death of her mother in November 1504, Joanna became queen regnant of Castile and her husband jure uxoris its king in 1506. Joanna's father, Ferdinand II, lost his monarchical status in Castile although his wife's will permitted him to govern in Joanna's absence or, if Joanna was unwilling to rule herself, until Joanna's heir reached the age of 20.Prawdin, Michael, The Mad Queen of Spain, p. 83.

Ferdinand refused to accept this; he minted Castilian coins in the name of "Ferdinand and Joanna, King and Queen of Castile, León and Aragon", and, in early 1505, persuaded the Cortes that Joanna's "illness is such that the said Queen Doña Joanna our Lady cannot govern". The Cortes then appointed Ferdinand as Joanna's guardian and the kingdom's administrator and governor.

Joanna's husband, Philip, was unwilling to accept any threat to his chances of ruling Castile and also minted coins in the name of "Philip and Joanna, King and Queen of Castile, Léon and Archdukes of Austria, etc." In response, Ferdinand embarked upon a pro-French policy, marrying Germaine de Foix, niece of Louis XII of France (and his own great-niece), in the hope that she would produce a son to inherit Aragon and perhaps Castile.Elliott, J. H., Imperial Spain

In the Low Countries, Joanna was kept in confinement, but when her father-in-law Maximilian (in semi-secrecy) visited them on 24 August 1505 she was released to welcome him. Maximilian tried to comfort Joanna with festivities and she spent weeks accompanying him in public events, during which she acted like a wise, prudent queen, as noted by the Venetian ambassador. To entertain Joanna, Philip and Maximilian (who was dressed incognito) jousted against each other at night, under torchlight. Maximilian told Philip that he could only succeed as a monarch if husband and wife were "una cosa medesima" (one and the same). After this, the couple reconciled somewhat. When Philip tried to gain support from Castilian nobles and prelates against Ferdinand though, Joanna firmly refused to act against her father.

Ferdinand's remarriage merely strengthened support for Philip and Joanna in Castile, and in late 1505 the pair decided to travel to Castile. Before they boarded the ship, Joanna forbade a ship with female attendants to join the trip, fearing that Philip would have illicit relationships with them. This action played right into Philip's and Ferdinand's propaganda against her. Leaving Flanders on 10 January 1506, their ships were wrecked on the English coast and the couple were guests of Henry, Prince of Wales (later Henry VIII), and Joanna's sister Catherine of Aragon at Windsor Castle. They weren't able to leave until 21 April, by which time civil war was looming in Castile.

Philip apparently considered landing in Andalusia and summoning the nobles to take up arms against Ferdinand in Aragon. Instead, he and Joanna landed at A Coruña on 26 April, whereupon the Castilian nobility abandoned Ferdinand en masse. Ferdinand met Philip at Villafáfila on 27 June 1506 for a private interview in the village church. To the general surprise, Ferdinand had unexpectedly handed over the government of Castile to his "most beloved children", promising to retire to Aragon. Philip and Ferdinand then signed the Treaty of Villafáfila secretly, agreeing that Joanna's "infirmities and sufferings" made her incapable of ruling and promising to exclude her from government and deprive the Queen of crown and freedom.

Ferdinand promptly repudiated the second agreement the same afternoon, declaring that Joanna should never be deprived of her rights as Queen Proprietress of Castile. A fortnight later, having come to no fresh agreement with Philip, and thus effectively retaining his right to interfere if he considered his daughter's rights to have been infringed upon, he abandoned Castile for Aragon, leaving Philip to govern in Joanna's stead.

Philip's death By virtue of the agreement of Villafáfila, the procurators of the Cortes met in Valladolid, Castile on 9 July 1506. On 12 July, they swore allegiance to Philip I and Joanna together as King and Queen of Castile and León and to their son Charles as their heir apparent. This arrangement only lasted for a few months.

On 25 September 1506, Philip died after a five-day illness in the city of Burgos in Castile. The probable cause of death was typhoid fever but there were rumors that his father-in-law, Ferdinand II, had poisoned him. Joanna was pregnant with their sixth child, a daughter named Catherine (1507–1578), who later became Queen of Portugal. As Joanna had no midwife at the time, she was assisted during childbirth by her lady-in-waiting, María de Ulloa.
