In the Historia Brittonum, there is a narrative in which Vortigern (Welsh: Gwrtheyrn), King of the Celtic Britons from Powys is interrupted whilst attempting to build a fort at Dinas Emrys.

[1][2] The Historia Brittonum was written c. 828, and by this point, the dragon was associated with a coming deliverer from the Saxons and, for the first time, as a symbol of independence.

[8] Cynddelw Brydydd Mawr, a court poet to Owain Gwynedd refers to him in one elegy, personifying him as "The golden dragon of Snowdonia of eagles".

[6][9] Henry VII recognised the red dragon upon its blessing at Saint Paul's Cathedral following his victory at Bosworth Field under the realm of 'England and Wales' in 1485; the United Kingdom would not recognise the flag's official status again until 1959,[10] despite the dragon being used by Romanised Celtic Britons since at least the fall of the Roman empire in the 6th century AD.

[11] The Senior line of the House of Aberffraw descended from Prince Llywelyn the Great in patriline succession and became extinct on the death of Owain Lawgoch in 1378.

Henry met and fought Richard III at the Battle of Bosworth Field, and took the English throne in victory.

However, the flag was the subject of derision, both because the tail pointed downwards in some iterations[21] and because the motto was a potential double entendre, used in the original poem to allude to the penis of a copulating bull.

The students passed through the turnstiles of the castle as ordinary visitors, climbed the stone steps to the Eagle Tower, and carried away the Union Jack, which had previously been removed during the morning.

During the 1999 Rugby World Cup, which was hosted in Wales, the opening ceremony used the motif of the dragon several times; the flag was worn on a dress by Welsh singer Shirley Bassey.

(1987) follows the story of a young disabled Welsh man, grounded in California, who regularly expresses nostalgia and a hope for return to his home country.

Prior to this update, The Daily Telegraph reported that users had "been able to send emojis of the Union Flag, but not of the individual nations".
