This course, historically expressed, is the story of the development of the bourgeoisie. If "political conditions are the decisive causes of economic conditions," the modern bourgeoisie would necessarily not have progressed as the result of a fight with feudalism, but would be the darling child of its womb. Everybody knows that the opposite is the case. The bourgeoisie, originally bound to pay feudal dues to the dominant feudal nobility, recruited from bond slaves and thralls, in a subject state, has, in the course of its conflict with the nobility captured position after position, and finally has come into possession of the power in civilized countries. In France it directly attacked the nobility, in England it made the aristocracy more and more bourgeois and finally incorporated it with itself as a sort of ornament. And how did this come about? Entirely through the transformation of economic conditions which was sooner or later followed either by the voluntary or compulsory transformation of political conditions. The fight of the bourgeoisie against the feudal nobility is the fight of the city against the country, of industry against landlordism, of economy based on money against economy based on natural products. The distinctive weapons of the bourgeois in this fight were those which came into existence through the development of increasing economic force by reason of the growth at first of hand manufacture and afterwards machine-manufacture and through the extension of trade. During the whole of this conflict the political power was in the hands of the nobility, with the exception of a period when the king employed the bourgeoisie against the nobility in order to hold one in check by means of the other. From the very moment, however, in which the bourgeoisie still deprived of political power began to be dangerous because of the development of its economic power the monarchy again turned to the nobility and thereby brought about the revolution of the bourgeois first in England and then in France. The political conditions in France remained unaltered until the economic conditions outgrew them. In politics the noble was everything, the bourgeois nothing. As a social factor the bourgeoisie was of the highest importance while the nobility had abandoned all its social functions and yet pocketed revenues, social services which it did not any longer perform. Even this is not sufficient. Bourgeois society was, as far as the whole matter of production is concerned, tied and bound in the political feudal forms of the Middle Ages, which this production, not only as regards manufacture but as regards handwork also had long transcended amid all the thousandfold gild-privileges and local and provincial tax impositions which had become mere obstacles and fetters to production. The bourgeois revolution put an end to them. But the economic condition did not, as Herr Duehring would imply, forthwith adapt itself to the political
