Shortly before the Soviet Revolution of 1917, Lenin wrote State and Revolution.
According to Lenin, a Communist Revolution is the only remedy for class struggle..
Drawing on detailed quotes from Karl Marx and Friedrick Engels, he lays down a Marxist view of the state, describes how a working-class Revolution will overthrow it, and goes further in showing how social democracy is not enough - even in democratic republics such as those enjoyed by many western countries today, the ruling class is still in control of society, and will never relinquish power.
