Catherine deā Medici
Catherine de' Medici.
Catherine deā Medici became regent for her son, Charles IX, following the premature death of his older brother, Francis II, on December 5, 1560.12
During the reign of Francis II, the Guise family had monopolized royal authority, effectively sidelining the queen mother. Upon Francis II's death, Catherine successfully secured the regency for herself to restore the crown's independence and counter the influence of the Guise extremists. She appointed Antoine de Bourbon, the king of Navarre and first prince of the blood, as lieutenant general to help stabilize the kingdom during this transition.12
