The first modern Eisteddfod was held in Aberdare South Wales in 1861.

However, the originals were a bardic festival of music and poetry first held by Lord Rhys son of Gruffydd of Deheubarth at his court in Cardigan in 1176.

There he held a grand gathering to which were invited poets and musicians from all over the country. A chair at the Lord's table was awarded to the best poet and musician, a tradition that continues in the modern day National Eisteddfod with the "Chairing of the Bard" ceremony at the end of the event.

"Who was considered the first king of Wales." in the category "Welsh History"

The Tudor dynasty or House of Tudor was a prominent European royal house of Welsh origin that ruled the Kingdom of England and its realms, including the Lordship and Kingdom of Ireland, from 1485 until 1603. Its first monarch was Henry Tudor, a descendant through his father, although ultimately not male line, of the rulers of the Welsh Kingdom of Deheubarth. Through his mother he descended from a legitimized branch of the English royal House of Lancaster. The Tudor family rose to power in the wake of the Wars of the Roses, which left the House of Lancaster, to which the Tudors were aligned, extirpated.
