A fraught subject... The English Civil War was sparked by Charles I's attempt to re-episcopalise (i.e. crypto-catholicise) the reformed Church of Scotland. Since the Glorious Revolution of 1688, the monarchs are, by definition, Anglican. The mainstream English narrative (as one learned in school) is that this was because James II was a Catholic; the subtext is that he promoted religious tolerance, and the end of the social and political ostracism of Catholics and the various "Dissenter" (Protestant) creeds. The monolithic Anglican establishment therefore gave him the boot, and wrote a constitution.

There is no "established" church in Scotland. The Church of Scotland, created in the Reformation, inherited the real estate of the Catholic church but it's Calvinist, or Presbyterian. There is the Episcopal Church (or "English Kirk") which belongs to the Anglican communion. And there are numerous splinter churches. In the town of Portree on the isle of Skye, population about 3000, I counted eight or nine churches listed on the street directory. Church of Scotland, Catholic, Free Church of Scotland, United Presbyterian Church, Jehovah's Witnesses, and God only knows what else. They appear to take their religion seriously, in the Islands at least. (In Edinburgh, most of the numerous churches we saw had been pressed into service as theatre venues. What would Knox say?)

So Scottish Royalists would do well to avoid the subject of religion...
