Let's talk about Britain first. As early as the promulgation of the Bill of Rights, the constitutional monarchy was established and the contemporary monarch was constitutionally bound, until now.

In France, 1789 broke out a revolution that shook the whole of Europe. The French Revolution established that the revolutionary government at that time was a harmonious, democratic, free and equal system. After Napoleon ascended the throne, he amended the Constitution and became a bourgeois monarchy. When Napoleon swept Europe, a Prussia was invaded by Napoleon, and revolutionary France occupied Vienna. The disintegration of the Holy Roman Empire (the First German Empire) laid the foundation for Prussia's post-war reunification of Germany. Napoleon formed the Rhine League and controlled the vassal state with his own will. So today's Germany is very similar to France in culture and many aspects, but I am afraid it is impossible to refer to Napoleon. The real Hitler, the dictator, did not explain. After World War II, countries strongly called for peace. Germany made the same mistake once and won't make it again.
