Heraldry inWales has a tradition distinct from that ofEnglish andScottishheraldry. There is evidence that heraldry was already being used in Wales by the middle of the thirteenth century; for instance, in Gwynedd, two sons ofLlywelyn the Great are recorded as having bornecoats of arms in this period.[1] Following the integration of Wales intoEngland in the fourteenth and fifteenth centuries, the Welsh heraldic tradition became merged into that of England.

Before theconquest of Gwynedd byEdward I, Wales was ruled by a number of Kings and Princes whose dominions shifted and sometimes merged following the vagaries of war, marriage and inheritance. All these Kings and Princes were ascribed personal coats of arms, often retrospectively if they lived before the dawn of heraldry, and these were borne by their descendants in Wales. The two principal Welsh kingdoms were those ofGwynedd, in the north, andDeheubarth in the south. Of these, the most successful, and the last, finally, to fall, was that of Gwynedd, and the arms now borne by the Princes of Wales as an escutcheon are the historic arms of the dynasty of Gwynedd as borne by the last native Princes of Wales, includingLlywelyn the Great andLlywelyn ap Gruffudd.
The arms associated with formerKingdom of Powys are a red lion rampant on a gold field. They were used by the House of Mathrafal when Powys was an independent kingdom and later by the Earls of Powis (de la Pole andde Cherleton families) up until the late Middle Ages and can now be found on various civic coats of arms.
The arms associated with the principal dynasty of south Wales (Deheubarth) are, on the other hand, a gold lion rampant on a red field within an indented (sometimes engrailed) gold border. Although never included in the English Royal Arms, they continue to be borne by families descended from the dynasty of Deheubarth: most notably by the Talbot family (Earl of Shrewsbury, etc.) which married an heiress of the dynasty in the 14th century.

Arms of houses and of influential people are often combined, as shown in this example of the quartered arms ofHughes of Gwerclas, which gives a broad overview of Welsh heraldry. The arms are quarterly of four:
Key features shown are the predominance of the Welsh dragon, the use of colour differences to distinguish branches of a family, and the use ofcrests. The arms here show an allegiance to both people and to Kingdoms within Wales.

A newRoyal Badge ofWales was approved in May 2008. It is based on thearms borne byLlywelyn the Great, the famous thirteenth century Welsh prince (blazoned quarterly Or and gules, four lions countercharged langued and armed azure), with the addition of the imperial crown atop a continuous scroll which, together with a wreath consisting of the plant emblems of the fourcountries of the United Kingdom, surrounds the shield.[34] The motto which appears on the scroll,PLEIDIOL WYF I'M GWLAD (I am true to my country), is taken from theNational Anthem of Wales and is also found on Welsh design£1 coins. The badge appears on the cover ofActs passed bySenedd Cymru (Welsh Parliament).[35]
The current badge follows in a long line of heraldic devices representing Wales. Its predecessors have all been variations on either theRed Dragon, an ancient emblem revived byHenry VII, or the arms of Llywelyn.
