The state is an extremely multifaceted phenomenon. The reasons of its origin are explained by many objective factors: biological, psychological, economic, social, religious, national and others. Their general scientific comprehension is hardly possible within the framework of one universal theory, though in the history of human thought such attempts were made, and quite successfully (Plato, Aristotle, Montesquieu, Rousseau, Kant, Hegel, Marx, Plekhanov, Berdyaev). The history of civilization knows dozens, hundreds of legal theories. For centuries, the deep minds of mankind have been fighting over the unravelling of the phenomenon of law, the discovery of its essence. Legal theories of the past were the conquest of human culture, the desire of scientific thought to penetrate into the very core of human relations. The class and economic conditionality of law is the most important fundamental position of Marxist theory. The main content of this theory is the idea that the right is the product of class society; the expression and consolidation of the will of the economically dominant class.
