Origin of Y Ddraig Goch

Y Ddraig Goch (the red dragon) is the national flag of Wales, and has been officially recognised as such since the 1950s. The white-over-green field is in the livery colours of the Tudors, the Welsh dynasty that once sat on the English throne.

Conventional wisdom is that the 'draco' standards of the Romans were adopted by the Britons, probably as a metal (possibly real gold) head with a windsock type of body made of silk. In the mouth was a whistling type device that would make sounds as it was waved with vigor. Supposedly used by King Arthur, certainly used by the Wessex lords in the 700s, the emblem has been used by Britons right up to the present time.

History of Welsh Flags
[Note: The following is excerpted from "A History of the Red Dragon" by Carl Lofmark, edited by G.A. Wells (No. 4, Welsh Heritage Series, Gwasg Carreg Gwalch, Llanrwst, Gwynedd, Wales; 1995; ISBN 0-86381-317-8)]
The origins of the Welsh Dragon were undoubtedly the Roman "draconi" standards of the cohorts, which were far more numerous than the legions, particularly after the gradual withdrawal of the latter. "... the people who were left behind when the legions withdrew forever must most naturally have thought of the Dragon as the symbol of that Roman civilisation to which they belonged and which they were now defending against the ravages of the barbarian invaders. It is generally agreed that resistance to the Saxons was first organized by Romans, or Romanized Britons, presumably on Roman lines ... For their battle standard no emblem was more natural than the familiar Dragon of the Roman cohort."

"The Welsh, as a distinct people, may be said to date from about the seventh century, when the advance of the Saxons to the Bristol Channel and the Mersey isolated them from the rest of Celtic Britain. The 'Historia Brittonum,' of about 800 A.D. (traditionally ascribed to the scholar Nennius), which drew on earlier sources, described a Red Dragon as the symbol of the British people in their wars against the White Dragon of the Saxons. ... Early in the Welsh literary tradition, in the tale 'Lludd a Llefelys,' this Red Dragon is associated with Merlin, who gives counsel to the earliest kings in Briton."

"From the very first records of the Welsh language the words 'draig,' 'dragon' mean 'warrior' and great warriors are referred to as 'pendraig,' 'pendragon,' i.e. 'chief dragon'."

"The only thing that remains unclear about the early British dragon is its colour. According to Nennius, the dragon of the Britons is red. ... The national dragon of Mediaeval Wales may be red, or firey, or golden. ... It may be that his colour was not yet fixed, though he was thought to resemble fire, his most natural element: for the colours, on those occasions when colour is mentioned, are those appropriate to fire, and never any other."

"While the warriors, chiefs and princes of Wales were constantly called 'dragons', we do not have any clear evidence to prove that they ever used a dragon, let alone a red dragon, as a military standard at any time before the fifteenth century. It is perfectly likely that it may have happened, but the literary and historical documents which we have contain no unambiguous reference to the use of a dragon banner by Welsh resistance fighters until 1401."

"The arms of Llywelyn's [the Last, proclaimed the first Prince of Wales in 1258, died 1282] father, Gruffudd ap Llywelyn Fawr [of the royal house of Gwynedd], were sketched by Matthew Paris (died 1259) and they show, quarterly or and gules (i.e. gold and red) four lions passant counterchanged. ... there is no dragon in the arms of Gwynedd. ... there is more reason to suppose that Llywelyn fought under the traditional Lions of Gwynedd, like other leaders of Gwynedd both before and after him, up to Owain Glyndwr and the Tudors."

An "englyn" written at the time refers to Llywelyn and his army, "There is my lord Llywelyn and tall warriors follow him; a thousand, a host in green and white."

"These are the colours in which the Black Prince, Edward of Woodstock, was to dress his Welsh contingent at Crécy in 1346: these men were, as D.L. Evans remarked, 'the first troops to appear on a continental battlefield in national uniform.' Thus, by the middle of the fourteenth century, green and white appear to have been understood as the national colours of Wales; they were to be used later by Henry Tudor as the field for the Red Dragon, and they remain to this day the colours of the national flag, upon which the Red Dragon is set."

"Owain Glendwr, ... in 1401-04 succeeded in conquering virtually the whole of Wales."

"One of the earliest great successes of his career was his siege of Caernarfon (2nd November 1401), at which he unfurled his banner, displaying a golden dragon on a white field, as the chronicler Adam of Usk records: 'in multitudine glomerosa vexillum suum album cum dracone aureo ibidem displicuit'."

"From 1404 onward we hear no more of Owain's use of the dragon emblem. It seems that, having
