The National Eisteddfod: A History
There is no mention of the Eisteddfod as we think of it today until the year 1176. At that time, a meeting was held at Cardigan Castle under the patronage of Lord Rhys, one of the princes of South Wales. There is not much mention of the Eisteddfod afterward for several centuries.
The first time the Eisteddfod unified with the Gorsedd was in Carmarthen in 1819. From then on, Eisteddfodau were held consistently, and the National Eisteddfod won its place in the hearts of the Welsh people.
In 1860, it was decided to have one major Eisteddfod every year, and it was in Aberdare in 1861, that the first National Eisteddfod was held. Except for the years of war in 1914 and 1940 and the Covid-19 pandemic in 2020 and 2021, the National Eisteddfod has now been held continuously since 1880.
