Slavery remained the basis of the whole productive system. The plebeians, midway between freemen and slaves, never succeeded in becoming more than a proletarian rabble. Rome indeed never became more than a city; its connection with the provinces was almost exclusively political and could, therefore, easily be broken again by political events.
Nothing is more common than the notion that in history up till now it has only been a question of taking. The barbarians take the Roman Empire, and this fact of taking is made to explain the transition from the old world to the feudal system. In this taking by barbarians, however, the question is, whether the nation which is conquered has evolved industrial productive forces, as is the case with modern peoples, or whether their productive forces are based for the most part merely on their association and on the community. Taking is further determined by the object taken.
A banker's fortune, consisting of paper, cannot be taken at all, without the taker's submitting to the conditions of production and intercourse of the country taken. Similarly the total industrial capital of a modern industrial country. And finally, everywhere there is very soon an end to taking, and when there is nothing more to take, you have to set about producing.
From this necessity of producing, which very soon asserts itself, it follows that the form of community adopted by the settling conquerors must correspond to the stage of development of the productive forces they find in existence; or, if this is not the case from the start, it must change according to the productive forces. By this, too, is explained the fact, which people profess to have noticed everywhere in the period following the migration of the peoples, namely, that the servant was master, and that the conquerors very soon took over language, culture and manners from the conquered. The feudal system was by no means brought complete from Germany, but had its origin, as far as the conquerors were concerned, in the martial organisation of the army during the actual conquest, and this only evolved after the conquest into the feudal system proper through the action of the productive forces found in the conquered countries. To what an extent this form was determined by the productive forces is shown by the abortive attempts to realise other forms derived from reminiscences of ancient Rome (Charlemagne, etc.).
Contradictions of Big Industry: Revolution Our investigation hitherto started from the instruments of production, and it has already shown that private property was a necessity for certain industrial stages. In industrie extractive private property still coincides with labour; in small industry and all agriculture up till now property is the necessary consequence of the existing instruments of production; in big industry the contradiction between the instrument of production and private property appears from the first time and is the product of big industry; moreover, big industry must be highly developed to produce this contradiction. And thus only with big industry does the abolition of private property become possible.
In big industry and competition the whole mass of conditions of existence, limitations, biases of individuals, are fused together into the two ******st forms: private property and labour. With money every form of intercourse, and intercourse itself, is considered fortuitous for the individuals. Thus money implies that all previous intercourse was only intercourse of individuals under particular conditions, not of individuals as individuals. These conditions are reduced to two: accumulated labour or private property, and actual labour. If both or one of these ceases, then intercourse comes to a standstill.
The modern economists themselves, e.g. Sismondi, Cherbuliez, etc., oppose "association of individuals" to "association of capital". On the other hand, the individuals themselves are entirely subordinated to the division of labour and hence are brought into the most complete dependence on one another. Private property, insofar as within labour itself it is opposed to labour, evolves out of the necessity of accumulation, and has still, to begin with, rather the form of the communality; but in its further development it approaches more and more the modern form of private property. The division of labour implies from the outset the division of the conditions of labour, of tools and materials, and thus the splitting-up of accumulated capital among different owners, and thus, also, the division between capital and labour, and the different forms of property itself. The more the division of labour develops and accumulation grows, the sharper are the forms that this process of differentiation assumes. Labour itself can only exist on the premise of this fragmentation.
