Excerpt: Heraldic labels are used to differentiate the personal coats of arms of members of the royal family of the United Kingdom from that of the monarch and from each other. In the Gallo-British heraldic tradition, cadency marks have been available to "difference" the arms of a son from those of his father, and the arms of brothers from each other, and traditionally this was often done when it was considered important for each man to have a distinctive individual coat of arms and/or to differentiate the arms of the head of a house from junior members of the family. This was especially important in the case of arms of sovereignty: to use the undifferenced arms of a kingdom is to assert a claim to the throne. Therefore, in the English royal family, cadency marks were used from the time of Henry III of England, typically a label or bordure alluding to the arms of the bearer's mother or wife. For the next three generations, the heir apparent differenced with a label azure, while other sons used a label or bordure of a different tincture, or bearing charges. After about 1340, when Edward III of England made a claim to the throne of France, a blue label did not contrast sufficiently with the blue field of the French quarter of the royal arms, accordingly most royal cadets used labels argent: that of the heir apparent was plain, and all others were charged. Bordures of various tinctures continued to be used into the 15th century. In the ordinary system of differences a label of three points (which has also been termed a label with three files) is the distinction of the eldest son during the lifetime of his father. In the oldest rolls of arms the labels are all of five points, but labels of three points were at an early period used interchangeably. Besides being used as mere temporary marks of cadency, labels are also employed as permanent distinctions, borne (like any other charge) by every member of some particular branches of certain families. Labels are the principal cadency
