It’s true.
The Roman Empire essentially morphed into the Catholic Church. It’s difficult to see it through a modern lens where so many are atheist/statist but they were the ones who controlled Western society for over a thousand years. Just look at the power they held over Kings, King Henry VIII being a good example.
As for England, yes. Theirs was the first major “transition” of superpower where the incumbent wasn’t defeated - they basically became a silent partner in the US via banks. Look into Keynes, and the emissaries the Poms sent out to the colonies to take over banking.
