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.

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.

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 Toro 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. 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.

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 (French: Antoine de 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.
