The Industrial Proletariat
The order of our investigation of the different sections of the proletariat follows naturally from the foregoing history of its rise. The first proletarians were connected with manufacture, were engendered by it, and accordingly, those employed in manufacture, in the working up of raw materials, will first claim our attention. The production of raw materials and of fuel for manufacture attained importance only in consequence of the industrial change, and engendered a new proletariat, the coal and metal miners. Then, in the third place, manufacture influenced agriculture, and in the fourth, the condition of Ireland; and the fractions of the proletariat belonging to each, will find their place accordingly. We shall find, too, that with the possible exception of the Irish, the degree of intelligence of the various workers is in direct proportion to their relation to manufacture; and that the factory-hands are most enlightened as to their own interests, the miners somewhat less so, the agricultural labourers scarcely at all. We shall find the same order again among the industrial workers, and shall see how the factory-hands, eldest children of the industrial revolution, have from the beginning to the present day formed the nucleus of the Labour Movement, and how the others have joined this movement just in proportion as their handicraft has been invaded by the progress of machinery. We shall thus learn from the example which England offers, from the equal pace which the Labour Movement has kept with the movement of industrial development, the historical significance of manufacture.
Since, however, at the present moment, pretty much the whole industrial proletariat is involved in the movement, and the condition of the separate sections has much in common, because they all are industrial, we shall have first to examine the condition of the industrial proletariat as a whole, in order later to notice more particularly each separate division with its own peculiarities.
It has been already suggested that manufacture centralises property in the hands of the few. It requires large capital with which to erect the colossal establishments that ruin the petty trading bourgeoisie and with which to press into its service the forces of Nature, so driving the hand-labour of the independent workman out of the market. The division of labour, the application of water and especially steam, and the application of machinery, are the three great levers with which manufacture, since the middle of the last century, has been busy putting the world out of joint. Manufacture, on a small scale, created the middle-class; on a large scale, it created the working-class, and raised the elect of the middle-class to the throne, but only to overthrow them the more surely when the time comes. Meanwhile, it is an undenied and easily explained fact that the numerous petty middle-class of the "good old times" has been annihilated by manufacture, and resolved into rich capitalists on the one hand and poor workers on the other. 
The centralising tendency of manufacture does not, however, stop here. Population becomes centralised just as capital does; and, very naturally, since the human being, the worker, is regarded in manufacture simply as a piece of capital for the use of which the manufacturer pays interest under the name of wages. A manufacturing establishment requires many workers employed together in a single building, living near each other and forming a village of themselves in the case of a good-sized factory. They have needs for satisfying which other people are necessary; handicraftsmen, shoemakers, tailors, bakers, carpenters, stonemasons, settle at hand. The inhabitants of the village, especially the younger generation, accustom themselves to factory work, grow skilful in it, and when the first mill can no longer employ them all, wages fall, and the immigration of fresh manufacturers is the consequence. So the village grows into a small town, and the small town into a large one. The greater the town, the greater its advantages. It offers roads, railroads, canals; the choice of skilled labour increases constantly, new establishments can be built more cheaply, because of the competition among builders and machinists who are at hand, than in remote country districts, whither timber, machinery, builders, and operatives must be brought; it offers a market to which buyers crowd, and direct communication with the markets supplying raw material or demanding finished goods. Hence the marvellously rapid growth of the great manufacturing towns. The country, on the other hand, had the advantage that wages are usually lower than in town, and so town and country are in constant competition; and, if the advantage is on the side of the town today, wages sink so low in the country tomorrow that new investments are most profitably made there. But the centralising tendency of manufacture continues in full force, and every new factory built in the country bears in it the germ of a manufacturing town. If it were possible for this mad rush of manufacture to go on at this rate for another century, every manufacturing district of England would be one great manufacturing town, and Manchester and Liverpool would meet at Warrington or Newton; for in commerce, too, this centralisation of the population works in precisely the same way, and hence it is that one or two great harbours, such as Hull and Liverpool, Bristol and London, monopolise almost the whole maritime commerce of Great Britain.
Since commerce and manufacture attain their most complete development in these great towns, their influence upon the proletariat is also most clearly observable here. Here the centralisation of property has reached the highest point; here the morals and customs of the good old times are most completely obliterateded; here it has gone so far that the name Merry Old England conveys no meaning, for Old England itself is unknown to memory and to the tales of our grandfathers. Hence, too, there exist here only a rich and a poor class, for the lower middle-class vanishes more completely with every passing day. Thus the class formerly most stable has become the most restless one. It consists today of a few remnants of a past time, and a number of people eager to make fortunes, industrial Micawbers and speculators of whom one may amass a fortune, while ninety-nine become insolvent, and more than half of the ninety-nine live by perpetually repeated failure.
But in these towns the proletarians are the infinite majority, and how they fare, what influence the great town exercises upon them, we have now to investigate.
 Compare on this point my "Outlines of a Critique of Political Economy" in the Deutsch-Französische Jahrbücher. In this essay "free competition" is the starting-point; but industry is only the practice of free competition and the latter is only the principle on which industry is based.-- Note by Engels.
