The State was the official representative of society as a whole; the gathering of it together into a visible embodiment. But, it was this only in so far as it was the State of that class which itself represented, for the time being, society as a whole:

in ancient times, the State of slaveowning citizens; in the Middle Ages, the feudal lords; in our own times, the bourgeoisie.

When, at last, it becomes the real representative of the whole of society, it renders itself unnecessary. As soon as there is no longer any social class to be held in subjection; as soon as class rule, and the individual struggle for existence based upon our present anarchy in production, with the collisions and excesses arising from these, are removed, nothing more remains to be repressed, and a special repressive force, a State, is no longer necessary.
