There is a dragon on the Welsh flag because it has been an emblem of Wales since the 5th century. Later, it became known as the Red Dragon of Cadwaladr and has been used in many battles by Celtic kings and the Tudors who were of Welsh descent. It was officially recognized in 1959.

Why is There a Dragon on the Welsh Flag? 

The origin of the red dragon dates back to the 5th century when, according to legend, the red dragon, representing the Celtic people, won in a battle against the white dragon, representing the Saxons (more on this story below).

Since then, the dragon has appeared in many Welsh texts and it became an emblem of Wales under Cadwaladr who was King of Gwynedd in North Wales between 655 - 682AD (source: BBC). This is when it became known as the Red Dragon of Cadwaladr.

Wales’ first recorded use of the dragon on their flag was in 1485 during the Battle of Bosworth Field in England when Henry Tudor (who was born in South Wales) defeated Richard III to become King of England.

This is also where the green and white colours of the modern flag came from as these were the colours of the Tudor house.

However, it wasn’t until much later in 1959 that the flag featuring the red dragon was officially recognised by the British Government as the flag of Wales (source: Wikipedia).

How Did the Dragon Become the Symbol of Wales?

As detailed in chapter 42 of the Historia Brittonum (a text written around 828AD detailing the history of the indigenous British people), the history of the red dragon can be traced back to the 5th century.

According to legend, Vortigern, King of the Celtic Britons in the 5th century, wanted to build a new castle on a hillside around 23km (14 miles) south of Caernarfon in North Wales.

However, his men and the materials for the castle kept disappearing. As he tried to find out why, a young boy named Emrys from Camarthen (who later became Merlin the Magician), warned him that beneath the hill were two sleeping dragons and an underground lake.

Vortigern’s instructed his men to keep digging at the site and they did indeed find a lake and two dragons, a red one and a white one. The boy explained to Vortigen that the red dragon represented him and his people, whilst the white dragon represented the Saxons, who occupied much of Britain at that time.

The two dragons fought and eventually the red dragon, which was considered the weakest, won and the white one was dispelled from the tent in which they fought.

The castle was then built and named after the boy, Dinas Emrys. This is how the red dragon became the symbol of Wales.
