WELSH & ENGLISH DRAGONS (Red & White Dragons)
Old Welsh tales use the Red Dragon to symbolize the resistance of the Welsh people to a group of powerful invaders. The story became so popular and such an important part of Welsh culture that the Red Dragon made its way onto the modern day flag of Wales.
Versions of this story use King Ludd and King Leffelys trying to solve the critical problem of two dragons terrorizing the peasants by their constant battles and shrieks.
Links to Arthurian legend can also be found in tales where Merlin explains to King Vortigern that his repeatedly collapsing castle is failing in its construction because it is being built on burial site of the Red and White Dragons.
