Say, a country has well-established democratic doctrines and principles. Is it practically possible for that country to directly switch to a monarchy? By practical, I mean the country must last reasonably long, and not just some short-lived monarchy, overthrown by the discontented public.
I'm talking about a direct reform, e.g. a president will reform the government. Countries who had long series of wars before achieving this are not counted.
On a side note, are there real world examples for countries with these types of histories (existing and still living)? I can't seem to find any.
