The researcher who has been helping PKH and Albion with Irish research has a great public YouTube channel on Irish Medieval History, I thought some of our mod followers might be interested in these videos too...
As well as topics from slightly earlier and later periods than our mod covers, there's a lot that are very relevant to our era such as "Who are the Irish Gallowglass Warriors?"
Thanks! I'm currently hoping not to re-design the Ireland bit of the map, but we do seem to be tweaking a few things that were previously declared 'done'!
