I understand it just fine and no, the first joint stock company was nearly 100 years before the civil war. Thats not soon before at all. It just really kills the narrative being spun.

Capitalism was nationwide here long before the civil war. Not only in the form of joint stock companies, ending merchantilism, but in the acts of enclosure forcing the yeomanry into the factories and workhouses (capital not land). Again, nearly 100 years before the civil war.

It was a war of religion and wherever you got this alternative narrative from is completely wrong. It was literally just fanatics killing each other over liking the wrong flavour of Jesus. Nothing meaningful changed after the war. Capitalism wasn't ushered in, as it was already here. Capital didn't become the dominant power due to it, as it already was the dominant power. CoE was already the dominant religion too. So, it wasn't changing the power structure of the existing dominant religion. So, wrong on every account that could make it what you claim.

Specifically in the UK, the Catholic/protestant power structure change was that the monarch decided to, essentially, make themselves both monarch and pope. I think you're confusing it with the German wars of religion and they weren't the same.
