Watch South to Black Power Online Free. In his provocative 2021 book, The Devil You Know: A Black Power Manifesto, New York Times opinion columnist Charles M. Blow calls for a “reverse Great Migration” of African Americans from the North back to the South to upend today’s political power structures while reclaiming the land and culture they left behind. South to Black Power does more than illustrate Blow’s enlightening ideas; we journey through Blow’s personal story, from his childhood in Louisiana to his role as father to young adult children in New York City, showing us the hard-won truths behind his vision for the future.
