The heraldic code of the Nasrid dynasty coat of arms is part of the tradition of the Christian kingdoms of Western Europe. The coat of arms of the Muslim kingdom of Granada is an exceptional example of the self-representation of a community through new concepts resulting from cultural crossbreeding. The two transverse stripes that accompany the dynasty's motto appear in the Nasrid coat of arms from the reign of Emir Mohammed V. These two stripes are the consequence of the nomination of Emir Mohammad V as a member of the Christian brotherhood "Orden de la Banda." Created by the Christian King Alfonso XI (1311-1350), the Order of the Scarf (Orden de la Banda), was a military brotherhood honoring chivalry and loyalty. The son of Alfonso XI, King Pedro I (1350-1366), invited Emir Mohammad V of Granada to join the brotherhood as a symbol of good diplomatic relations between the two kingdoms. Later, King Juan II of Castile (1406-1454) did the same with Emir Yusuf IV of Granada.
