Different Systems of Democracy
Democracy is not a sharply defined form of government that would need to be implemented in just one and no other way. Both in theory and in practice there are as many systems of democracy than democratic countries. Nevertheless there are some general features as well as some groups of democratic systems that may be distinguished from each other.
Contrary to other authors, I will not try to present pure and ideal theories but rather start from the other side: how can the different systems of democracy be distinguished in everyday political life.Source from : http://www.democracy-building.info/systems-democracy.html
