European immigrants brought developed labor traditions that shaped American radicalism.

Evidence

Earlier, as we have seen, the African and Afro-American agrarian workers had supplied the critical surplus value that supported the transformation of the economy into an industrialized and ultimately capital-intensive one. In turn, late nineteenth-century European immigrants—expropriated, trained, reproduced, and disciplined by European sectors of the world economy (in Germany, England, Ireland, and Italy primarily)—constituted the labor forces uniquely developed and historically necessary for the American industrial transformation. But most of these European immigrant workers had come from societies in which labor movements were already developed. In fact most of these movements had by the mid-nineteenth century developed unique and particular complexes of tactics, strategy, and ideology. Whole traditions in these labor movements and oppositions in those traditions had been achieved. These were a part of the political, organizational, and ideological cultures that accompanied the foreign workers to America. — Cedric J. Robinson, Black Marxism_ The Making of the Black…, 989
