What country with a majority Islamic population is currently going through a secularization process?
In any case, I only care about the practicalities. In terms of what they try to achieve, there’s no real difference between the Christian and Muslim dominionists.
And centuries of liberal democracies where the church was just one institution that had no direct rule over its subjects?
In general, the Church's political power has waned over the last 500 years or so, but there are an awful lot of calls from Republicans saying that this is where we have gone wrong.
One only look to the political donations of Opes Dei (Catholic branch dedicated to getting Cristian influence over the "Lay" sphere) to see them as major power players today. The Heritage Foundation (main writers of Project 2025) are intimately bound with the organization. And Chief Justice Roberts is also associated.
So they may not be "direct" rulers, they are major power players.
