Who were the better fighters?
Norse treated British Isles like a playground. Just because the Irish might defeat any number of Norse at some point while the Norse ruled and defeated the natives there doesn't make the Irish good.
Celts have been on cultural retreat since the Bronze Age, meanwhile Germanics blossomed since the fall of Rome.
Remember the time the Celts ruled over Scandinavia? No?
Battle of Clontarf 6 thousand and 600 Vikings, only 600 survived the battle. They never defeated the Irish at all. They set up a few cities like our capital Dublin and ruled them. But They never ruled the rest of the country in large areas, the Gaelic kings had complete control. They tolerated the Vikings.
Who would want it, you snownigger?
The only good Norseman is a Norse-Gael who unanimously agreed that their Gaelic heritage was much more prestigious than being a glorified rapist and squatter.
Their cities were legit. But they did not control most of the inner country. They did, they reduced their power considerably after clontarf. But before that it was because the 200 plus Irish kings were all too busy killing each other to give two shits about the Vikings, the majority only united after Brian Boru united them and became the High King of Ireland, and kicked the shit into the Norsemen and their Irish lackeys.
I see. Isn't it kinda the norm that when you unite the germ-Irish peoples under one banner that the outlier is fucked?
Any Jarl in the area would've been just like any other minor king it seems.
