Question

Why could Britain become dominant among welsh ,Scot and Irish?

Answer 1

Answer:

Recently, I've been searching a lot about Scotland, Ireland, Wales, and England. One after the other, England vassalized its neighbors and became the head of Great Britain.

I can understand that Wales, which was really decentralized, couldn't really stop the English. But for Scotland and Ireland, how was it done?

In history lessons, we learn that Ireland was effectively separated into many fiefdoms (4 before the British invasion) but supposedly united against invaders. Thus, how could they lose their lands so easily? Was their army too old? Was there no will to keep their lands?

For Scotland, they indeed often fought against England and often allied with France for protection. They were nonetheless crushed by the English.
