Juana la Loca.
Joanna the Mad.
But while Europe remembered the grieving widow beside a corpse, something even more consequential was happening around the living queen.
She was losing control of her kingdom.
Her Father Returned
Philip’s death created a political vacuum.
Joanna was still queen.
But who would actually govern Castile?
Ferdinand returned.
According to the Real Academia de la Historia, after Philip’s death Joanna wrote to her father asking him to return and take responsibility for government. Ferdinand subsequently resumed control.
Whatever Joanna’s precise intentions or condition during this period, her effective political independence rapidly diminished.
Then, in 1509, came the decision that would define almost the entire remainder of her life.
Joanna was taken to Tordesillas.
She would not leave as a free ruling queen again.
The Biblioteca Virtual Miguel de Cervantes records that she arrived at the royal palace there in March 1509 and remained confined for 46 years, first under the authority of her father Ferdinand and later under that of her son Charles.
She was not yet 30.
She would die there at 75.
The numbers alone make the story extraordinary.
Philip had been dead for fewer than three years when Joanna entered Tordesillas.
Henry VIII had not yet become King of England.
Martin Luther had not yet published the Ninety-Five Theses.
The Protestant Reformation had not begun.
Joanna would still be confined when all of those events had become history.
And throughout much of that enormous span of time, there was another uncomfortable fact:
She was still Queen of Castile.
The Queen Who Reigned Without Ruling
Ferdinand governed Castile after Joanna’s confinement until his death in 1516.
Then the political situation became even stranger.
Joanna’s son Charles claimed royal authority.
But Joanna was alive.
Legally, she had not simply ceased to exist because she had been placed behind the walls of Tordesillas.
The documentary record reflects that constitutional awkwardness. Joanna remained queen, while Charles exercised the power associated with kingship. Academic material hosted by the Cervantes Virtual library notes that Joanna remained queen alongside him until her death in 1555, even though she had been effectively incapacitated and confined.
The Prado similarly dates Joanna’s reign as Queen of Castile from 1504 until 1555, while noting that she exercised no effective power after 1506.
It created one of the strangest royal arrangements in European history.
A queen existed.
Her name and legal status mattered.
