Heraldry in Wales has a tradition distinct from that of English and Scottish heraldry. There is evidence that heraldry was already being used in Wales by the middle of the thirteenth century; for instance, in Gwynedd, two sons of Llywelyn the Great are recorded as having borne coats of arms in this period. Following the integration of Wales into England in the fourteenth and fifteenth centuries, the Welsh heraldic tradition became merged into that of England.

Of the Kingdoms
Before the conquest of Gwynedd by Edward 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 of Gwynedd, in the north, and Deheubarth 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, including Llywelyn the Great and Llywelyn ap Gruffudd. The arms associated with former Kingdom 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 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 are, on the other hand, a gold lion rampant on a red field within an indented 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 which married an heiress of the dynasty in the 14th century.
Use
Arms of houses and of influential people are often combined, as shown in this example, which gives a broad overview of Welsh heraldry. In the first main quarter, it shows quarterly the arms of Kingdom of Powys Fadog, Cilin ap y Blaidd Rhudd, Elystan Glodrydd and Tudor Trevor, Lord of Herford; in the second main quarter, the Kingdom of Powys, Cadwgan ap Elystan Glodrydd, the Kingdom of Powys Fadog, and Howel ap Meurig ; in the third main quarter, Roger of Bryntangor, Tudor ap Griffith Vychan, the Kingdom of Gwynedd and Owain I ap Gruffydd; and in the fourth main quarter, the Kingdom of Deheubarth, Philip ap Ivor, Gruffydd ap Cynan and Edwin of Tegeingl. Key features shown are the predominance of the Welsh dragon, the use of colour differences to distinguish branches of a family, and the use of crests. The arms here show an allegiance to both people and to Kingdoms within Wales.
A new Royal Badge of Wales was approved in May 2008. It is based on the arms borne by Llywelyn the Great, the famous thirteenth century Welsh prince, with the addition of the imperial crown atop a continuous scroll which, together with a wreath consisting of the plant emblems of the four countries of the United Kingdom, surrounds the shield. The motto which appears on the scroll, PLEIDIOL WYF I'M GWLAD, is taken from the National Anthem of Wales and is also found on Welsh design £1 coins. The new badge appears on the cover of Assembly Measures passed by the National Assembly for Wales. The current badge follows in a long line of heraldic devices representing Wales. Its predecessors have all been variations on either the Red Dragon, an ancient emblem revived by Henry VII, or the arms of Llywelyn.
