It was only that easy to dismiss a sick queen and have legitimate reasoning for her life long imprisonment. First by her husband, then by her father, and later on by her own son. However she only showed signs of manic behavior and clinical depression when she was in under duress by her treatment from her husband and father. The men in her life just wanted her out of the way so they could take her rightful crown.
Joanna was married to the Archduke Philip the Handsome. Joanna and Philip's marriage was filled with obsessive jealousy and later they had separated when Philip left her in Spain to go home with out her. She was in Spain to be become sworn heir to the Castile kingdom. After Philips death it is rumored that Joanna went mad some accounts claim that she took her husband's corpse with her to Tordesillas to keep it close to her.
She gave birth to six children two emporers and four queens. Her youngest Catherine became Queen of Portugal. Catherine was kept with her mother in her prison cell during her grandfather's time as regent. Nobody would dare take Catherine off her mad mother so Catherine stayed with Joanna. She remained with her disturbed mother until the arrival in Spain of her eldest siblings Eleanor and Charles.One key point is that whether it was the rebels or her family after her, she never signed away her rights to her queenship, she would live as regent queen until her death.
I am very passionate about Joanna because of a recommended read to me by my absolute favorite author Robin Maxwell. C.W. Gortner's The Last Queen is one of the best books I have ever read. It is a really eye opening point of view, with complete raw emotions of a vivid what if real life novel. A doomed Queen. Never allowed to rule.
"Juana of Castile, the last queen of Spanish blood to inherit her country’s throne, is an enigmatic figure, shrouded in lurid myth. Was she the bereft widow of legend who was driven mad by her loss, or has history misjudged a woman who was ahead of her time?"
