Northern capital abandoned Black allies once it dominated the southern economy

Evidence

It was in this fashion that the bond between the two elements of the southern working class failed to materialize. By necessity, Du Bois felt, Blacks fixed class alliances with northern capitalists and petit bourgeois Radical Republicans. Both alliances were by nature short-lived. Once Northern capital had sufficiently penetrated the southern economic sector so as to dominate its future development, it ceased to depend on Black electorates and state legislatures responsive to Blacks and the radical petit bourgeoisie. The alliance ended with the withdrawal of Federal troops from the South and the destruction of the governments supported by the bureaucracy of occupation. By the 1880s, the under-capitalized character of southern agrarian production was established and the need for external sources of raw materials more than apparent. In Mexico, the Philippines, Haiti, the Caribbean and Pacific islands, and elsewhere, northern capitalists constructed their own forms of slavery: but ones for which they could not easily be held accountable or among which they would be compelled to live. — Cedric J.
