It was such a massive task to establish the Roman race

"The discovery of gold and silver in America, the extirpation, enslavement and entombment in mines of the aboriginal population, the beginning of the conquest and looting of the East Indies, the turning of Africa into a warren for the commercial hunting of black-skins, signalised the rosy dawn of the era of capitalist production. These idyllic proceedings are the chief momenta of primitive accumulation. On their heels treads the commercial war of the European nations, with the globe for a theatre.

Colonial system, public debts, heavy taxes, protection, commercial wars, &c., these children of the true manufacturing period, increase gigantically during the infancy of Modem Industry. The birth of the latter is heralded by a great slaughter of the innocents. Like the royal navy, the factories were recruited by means of the press-gang.

With the development of capitalist production during the manufacturing period, the public opinion of Europe had lost the last remnant of shame and conscience. The nations bragged cynically of every infamy that served them as a means to capitalistic accumulation.  ...[I]t is trumpeted forth as a triumph of English statecraft that at the Peace of Utrecht, England extorted from the Spaniards by the Asiento Treaty the privilege of being allowed to ply the negro trade, until then only carried on between Africa and the English West Indies, between Africa and Spanish America as well. England thereby acquired the right of supplying Spanish America until 1743 with 4,800 negroes yearly. This threw, at the same time, an official cloak over British smuggling. Liverpool waxed fat on the slave trade. This was its method of primitive accumulation.

Whilst the cotton industry introduced child-slavery in England, it gave in the United States a stimulus to the transformation of the earlier, more or less patriarchal slavery, into a system of commercial exploitation. In fact, the veiled slavery of the wage workers in Europe needed, for its pedestal, slavery pure and simple in the new world.

Tantae molis erat, to establish the 'eternal laws of Nature' of the capitalist mode of production, to complete the process of separation between labourers and conditions of labour, to transform, at one pole, the social means of production and subsistence into capital, at the opposite pole, the mass of the population into wage labourers, into 'free labouring poor,' that artificial product of modern society. If money, according to Augier, 'comes into the world with a congenital blood-stain on one cheek,' capital comes dripping from head to foot, from every pore, with blood and dirt."
