Y Ddraig Goch (Welsh Dragon). The Romans used the dragon as one of their symbols of power. Into battle they would carry a metal head of a dragon in which they would light a fire. This would burn fiercely in the wind and seems to be where all the legends of fire breathing dragons come from. When the Romans left Britain it seems that the dragon was adopted by others as their symbol of power. Hence the Welsh Dragon of today.
Today my country voted to leave the EU - a vote to become more right wing & insular, based no doubt on making us "great" again. Be careful what you wish for in the US election...if great means divisive it's a sad day for all of us
