The article deals with the relationship of such concepts as the world-system and civilisation, both living independently and co-existing in time and space. World-systems and civilisations may be forced to unite into hyper-systems, or world-empires of different kind—self-sufficient, militarist-parasitic, and mixed type. Militarist empires-parasites can be settled and nomadic. Nomadic or bivouac empires are empires-armies, which exist only in movement. Stopping leads either to the death of the empire-army, or to the transformation into one but usually several stationary empires, mostly also militarist-parasitic.
