It has to be added that a significant amount of "pillarisation" https://en.wikipedia.org/wiki/Pillarisation https://en.wikipedia.org/wiki/Pillarisation was the norm, not an exception, across western Europe in the nineteenth century. Usually it was either a Catholic and a Protestant pillar, or a Catholic and a liberal or socialist one, or some combination. A lot of it blew away around the 'Sixties, but significant amounts remain. It wasn't and isn't unheard of in the US either, viz. for example the HBCUs or the Evangelical parallel universe.
