The UNIA and Brotherhood, not Moscow, primed Black nationhood.

Evidence

However, in the background were the UNIA and the Brotherhood. They had established the political and ideological preconditions for the party’s policies and its successes. It was the UNIA that had embodied the Black radical tradition and primed the Black masses with a sense of nationhood. It was the UNIA and the ABB through which many of the early Black activists in the party had passed. And it was the UNIA and the Brotherhood that had demonstrated the capacities of Blacks to organize politically and respond ideologically. It remains a telling point on the nature of the early American Communist movement that the significance of these examples had to depend upon Soviet-directed policy to be revealed. — Cedric J.

Categorization

• DEEPTHINKING: The crucial inversion: the indigenous Black radical tradition (UNIA, Brotherhood) actually created the preconditions for the party’s success, and the party’s Soviet authority had to ‘authorize’ recognizing what already existed — a dense claim about where the Black radical tradition’s vitality truly originated.
• XREF: Directly serves the reader’s origin question about the Black radical tradition — situates its source in UNIA and ABB rather than in Soviet direction.
• ADDENDUM: Connects to the reader’s interest in the Black radical tradition’s rise and fall that guides this whole read.
