CNN —Two powerful documentaries explore different aspects of Black history this week, in each case shedding light on misrepresented or under-covered chapters. Presented by Barack Obama’s company under its Netflix deal, “Descendant” examines the discovery of a long-sunk ship that brought enslaved Africans to Alabama, while “The Rebellious Life of Mrs. Rosa Parks” reclaims a figure whose legacy was too often characterized as the product of tired feet. Rosa Parks” highlights the selflessness of its subject and seeks to provide a detailed portrait of a woman who, through the vagaries of history, was frequently reduced to a symbol. Parks, rather, wanted – indeed devoted her life to fighting for – justice and equality. “The Rebellious Life of Mrs. Rosa Parks” premieres October 19 on Peacock.
