> Put another way - that would seem to be an effect, not a cause.
Protestantism does seem to become the preferred variant of Christianity in areas of bottom-up power systems, such as the UK (at least wrt Magna Carta), which does make perfect sense given the Vatican being the ultimate in top-down thinking.
Magna Carta (1200s) was issued 300 years before England defected from Catholicism (1500s), so I think we may be looking at the wrong thing as "the cause" here.
