Did the tradition of absolute rulers in Russia and China effect their adoption and interpretation of Communism with an all powerful state? Are constitutional monarchy and democracy in western Europe based on the feudal system with a weak king. In the 18th and early 19th century, Britain was sort of an aristocratic republic. Is it and other states still really ruled by the aristocracy? It seems like the federal system in the US and Germany is based on the feudal system. Particularly in Germany it is similar to the system of little states under the Holy Roman Empire.
