After all, the RF are a symptom of the way power, privilege and wealth are distributed, not the cause. That doesn't change by getting rid of the RF, it simply replaces one dysfunctional system of concentrating power with another.
Russia - Tsarism replaced by the Soviet Union and now Putin.
Germany, I would say that the complete destruction of society that was created by and followed the Third Reich was the significant change. The Kaiser was followed by the Nazis, who were in the mould of Imperial Germany and the Kaiser. Not a model to follow.
France - well, it's taken 200 years, a couple of Bonapartes with their European wars, and the failed state under de Gaulle.
Eastern European countries - RF never very deeply established, sort of bolted on as the Ottoman/Austro-Hungarian/Prussian Empires fragmented, then Soviet takeover. None perhaps a great model on lack of corruption and political stability? Though a number muddling through quite successfully? Happy to be corrected.
Western European countries - several constitutional monarchies of varying styles.
I am not so familiar with other continents, so don't really have a view on their various constitutional arrangements. Lived for a number of years in South Africa, where corruption and nepotism are alive and well under a supposedly democratic President.
