Marx and Engels systematically expressed their basic views on the modern state through such articles as Criticism of Hegels Philosophy of Law. They oppose all forms of monarchy, including constitutional monarchy, and advocate peoples sovereignty rather than monarchy. According to Marx and Engels, republicanism is an abstract form of state of democracy, and modern state is democratic republicanism. At the same time, Marx put forward that the future revolution is a social revolution (proletarian revolution), abolishing private ownership, eliminating class and class confrontation, and realizing the free and comprehensive development of human beings. However, what kind of state system the social revolution is going on has become a realistic problem. To this end, Marx and Engels put forward two ways: in a country that has not yet established a modern state system, the proletariat must overthrow the autocratic system, seize power and move towards socialism through the Democratic Republic in order to carry out social revolution. In a country where the modern state system is already mature, the proletariat must smash the state apparatus of the bourgeoisie and move towards socialism through the Paris Commune (social republic) in order to carry out social revolution. They believed that the two approaches are consistent in the ultimate realization of the dictatorship of the

proletariat.
