The history of Wales is filled with many kings and kingdoms, but the kingdom of Dyfed, formed from lands in Pembrokeshire and Carmarthenshire, had a very unique trait. This Welsh kingdom possessed an Irish dynasty, an attribute only found twice throughout Welsh history.
In this video I will be examining the history of this Irish kingdom in Wales in-depth, from the Celtic tribes that inhabited Wales to the Roman invasion, from the colonisation of this Irish dynasty to the incursions of the Vikings and the Anglo-Saxons, and we will see how such a unique piece of Welsh history came about, and how the history of Wales was forever changed by its actions.

  • "The stones" of Stonehenge did not originate in Dyfed. SOME of them did. The smaller bluestones were transported from the Prescelli mountains. However, the huge "hanging" sarsens which everyone associates with the monument, come from up the road in Wiltshire.
  • See this is where YouTube and internet is at its best with people adding what they know and discussing learning grieving and sharing. ❤
  • @MCKevin289
    I learned about this kingdom in my Irish archaeology class at UCC. The first records of the Irish language were found in wales if I remember correctly.
  • @Amcc38383
    Love from Ireland to our Celtic brothers across the sea🇮🇪❤🏴󠁧󠁢󠁷󠁬󠁳󠁿
  • @Daniel-en1on
    The Déise is a common nickname for County Waterford and it’s city to this day.
  • I think it's very interesting that there were so many small and separate kingdoms so long ago. The Welsh language is quite complex, especially when you see the words spelled out
  • I'm i live in Liverpool and I'm of welsh decent and its so nice to see videos like this especially because my mum is of irish decent
  • @Spikeyny
    My mum is from Dyfed (Caerfyrddin), Dad Munster Irish (Nenagh). Much closer cultures than I thought!
  • @neilevans4352
    nice to see irish and scots comments here mutual history being kept alive.
  • An interesting fact about Hywel Dda: He is the only Welsh king before the Norman Conquest for whom a coin type is known. Although it is probably an English coinage with a mintmaster from Chester, the unique specimen names Hywel as king.
  • Good effort on the pronunciations , I'm not gonna deduct any points for mispronouncing anything, I'd be hard pressed to find an Irish person who can properly pronounce old Irish names. And as an Irish person living in Wales this was really interesting, thank you!
  • Greetings from Waterford, ancestral home of the Deise. Congratulations on an excellent video outlining that part of your and our shared history. Unfortunately many Irish people are not aware of that part of their history. Congratulations again, and thank you so much for such an excellent presentation.
  • @Nibelheim1989
    So glad I came across this channel, great videos and very well put across. As a Scot, always nice to see more media on my Celtic brothers and sisters too.
  • @faelan1950
    Very very nice video! Here in Ireland we still call Co. Waterford the Déise, the dialect of Irish spoken is called "Gaeilinn na nDéise", or "the Irish of the Déise". The county I'm from (Co. Laois) originally spoke a very similar dialect to what is spoken in Irish-speaking areas in the Déise (such as An Rinn).
  • Hello again, I apologise for such a long wait, hopefully it will have paid off! I spent a lot of time trying to improve the audio, so I hope it sounds a lot better than my last video. If you enjoyed this video make sure to like/subscribe/email your neighbour about it/share it around! Thanks
  • These (limited) Welsh videos are hurting my head - the names, cities and kingdoms seem impossible to pronounce and difficult to spell, AND it’s ALL brand new to me. Quite familiar with Brit history, and some Scot/Irish history, but NOT Welsh history at all. VERY glad to see these videos, though they’re rather fast-paced (I’M OLD). Anyway, thank you for posting them and for teaching me totally new stuff!
  • I'm intrigued, I've only visited Pembrokeshire once, which was back in the 90's. Beautiful part of the country, (I was in the Tenby/Castlemartin area) and the friendliest people I've ever met in the UK. I wasn't aware of the Irish connection at the time, perhaps that shared heritage was, in part at least, the reason for such a warm welcome. Looking forward to catching up on your other work, I also love your style of narration. Thank you.
  • @mrwelshmun
    Thoroughly enjoying your videos mate! Nice to see someone else telling the story of Wales
  • Interestingly, the Normans who invaded Ireland in 1169 came from Wales. The links between Ireland and Wales are deep.
