Cruz de Borgoña
The royal standard is the personal banner of the monarch. The guidon, of military use, was formed from the reign of Philip II by the same elements of the standard but incorporating the Cross of Burgundy, a fringe and a "cordoncillo". During the period of the House of Austria, the Cross of Burgundy did not appear frequently in the royal standard. The Catholic Monarchs and Charles I (as monarchs of Castile) used the guidon of the Castilian monarchs, the "Banda de Castilla" which was a square flag of crimson color in which there was a band between two dragons. The Catholic Monarchs included in the Band of Castile the yoke and arrows which were replaced with the Columns of Hercules during the reign of Charles I. Fernando the Catholic also used the guidon that corresponded to him as monarch of Aragon. The Catholic Monarchs also frequently used, since 1492, a banner that consisted of a white cloth with their coat of arms.
