Juana Enriquez de Córdoba, 5th Lady of Casarrubios del Monte, was a Castilian noblewoman who became Queen of the Kingdoms of the Crown of Aragon.
Background
She was a daughter of Fadrique Enríquez, Count of Melba and Rueda and Mariana Fernández de Córdoba y Ayala, 4th Lady of Casarrubios del Monte. Born in Torrelobatón, she was a great-great granddaughter of Alfonso XI of Castile. She succeeded her mother in 1431.
Career
Although John ceased to be de jure uxoris monarch of Navarre on his wife"s death, he never ceded power to his heir, Charles, Prince of Viana, and Juana was thus styled Queen of Navarre. Such breaking of the law of succession led to a confrontation with the Generalitat of Catalonia and a conflict between farmers and nobles, the outbreak of Navarrese Civil War. Queen Juana"s children were Ferdinand II of Aragon who married the future Queen Isabella I of Castile and reigned with her as King of Castile, and Joanna, who married Ferdinand I of Naples and thus became Queen of Naples.
However, Juana died on 13 February 1468 from breast cancer, a year before the marriage occurred.
