At some point in this time period, the Royal Council became known as the Council of Castile, to reflect that the Council's power extended only over Castile and not the whole empire. With the growth of Spain's overseas conquests, and the prodding of Charles' grand-counselor and close friend Mercurino Guttinara, the Council of Castile expanded and split. Between the years 1522-1524 the Council of Castile reorganized the government of the Kingdom of Navarre, dismissing its viceroy, the Duke of Nájera. A Council of Finance ("Hacienda") was created, and on 1 August the Council of the Indies () was split from the Council of Castile. Thirty years later, in 1555, the Council of Italy was formed, yet another offspring of the Council of Castile. Guttinara also saw the establishment of the "Consejo de la Cámara de Castilla", an inner circle of the Council of Constile. The "Consejo" was composed of three or four trusted members of the Council who had power to deal with unpopular or secret issues.
