Although John ceased to be "de jure uxoris" monarch of Navarre on his wife's death, he never ceded power to his son, Charles, Prince of Viana, and daughter, "de jure" Blanche II of Navarre, a decision which Juana supported. Such breaking of the law of succession led to a confrontation with the Crown of Aragon and a conflict between farmers and nobles, the outbreak of Navarrese Civil War. Accused of having ordered the poisoning of Charles, her stepson, who died in 1461, Juana fled to Girona, seeking the protection of the bishop.
