Juana de Castro

Among her advisors were her uncle-in-law Enrique Enríquez the Younger and Men Rodríguez de Sanabria [es].

[2] In 1354, after the death of her husband Diego López de Haro, with whom she had a son, she met Peter of Castile.

Historian Juan Blas Sitges y Grifoll [es] argued that Castro agreed to marry Peter out of ambition rather than love.

As told by chronicler Pero López de Ayala: Castro demanded Peter to nullify his marriage with Blanche of Bourbon; he complied and had bishops Juan Lacero [es] and Sancho Blázquez Dávila [es] carry out the act.

She was pronounced Queen of Castile, though the marriage lasted one day before Peter left her.
