No close research into pre-Revolutionary currents and movements is necessary to understand that the Revolution was brought about by the dissatisfied trading class as the only means of securing absolute freedom of trade. Notwithstanding the view often presented that it was an altruistic movement for the freedom of man, it was essentially an economic struggle fathered by the trading class and by a part of the landed interests. Admixed was a sincere aim to establish free political conditions. This, however, was not an aim for the benefit of all classes, but merely one for the better interests of the propertied class. The poverty-stricken soldiers who fought for their cause found after the war that the machinery of government was devised to shut out manhood suffrage and keep the power intact in the hands of the rich. Had it not been for radicals such as Jefferson, Paine and others it is doubtful whether such concessions as were made to the people would have been made. The long struggle in various States for manhood suffrage sufficiently attests the deliberate aim of the propertied interests to concentrate in their own hands, and in that of a following favorable to them, the voting power of the Government and of the States. With the success of the Revolution, the trading class bounded to the first rank. Entail and primogeniture were abolished and the great estates gradually melted away. For more than a century and a half the landed interests had dominated the social and political arena. As an acknowledged, continuous organization they ceased to exist. Great estates no longer passed unimpaired from generation to generation, surviving as a distinct entity throughout all changes. They perforce were partitioned among all the children; and through the vicissitudes of subsequent years, passed bit by bit into many hands. Altered laws caused a gradual disintegration in the case of individual holdings, but brought no change in instances of corporate ownership. The Trinity Corporation of New York City, for example, has held on to the vast estate which it was given before the Revolution except such parts as it voluntarily has sold.
