According to Marxist–Leninist thought, the state is a repressive institution led by a ruling class. This class dominates the state and expresses its will through it. By formulating law, the ruling class uses the state to oppress other classes and forming a class dictatorship. However, the goal of the communist state is to abolish that said state. The Soviet Russia Constitution of 1918 stated: "The principal object of the Constitution of the R.S.F.S.R., which is adapted to the present transition period, consists in the establishment of a dictatorship of the urban and rural proletariat and the poorest peasantry, in the form of a powerful All-Russian Soviet power; the object of which is to secure complete suppression of the bourgeoisie, the abolition of exploitation of man by man, and the establishment of Socialism, under which there shall be neither class division nor state authority". The communist state is the dictatorship of the proletariat, where the advanced elements of the proletariat are the ruling class. In Marxist–Leninist thinking, the socialist state is the last repressive state since the next stage of development is that of pure communism, a classless and stateless society. Friedrich Engels commented on the state, writing: "State interference in social relations, becomes, in one domain after another, superfluous, and then dies out of itself; the government of persons is replaced by the administration of things, and by the conduct of processes of production. The state is not 'abolished'. It dies out."
