Böcker av Aaron Robertson

How do the disillusioned, the forgotten, and the persecuted not merely hold on to life but expand its possibilities and preserve its beauty? What, in other words, does utopia look like in black?These questions animate Aaron Robertson's exploration of Black Americans' efforts to remake the conditions of their lives. Writing in the tradition of Saidiya Hartman and Ta-Nehisi Coates, Robertson makes his way from his ancestral hometown of Promise Land, Tennessee, to Detroit - the city where he was born, and where one of the country's most remarkable Black utopian experiments got its start. Founded by the brilliant preacher Albert Cleage Jr., the Shrine of the Black Madonna combined Afrocentric Christian practice with radical social projects to transform the self-conception of its members. Central to this endeavour was the Shrine's chancel mural of a Black Virgin and child, the icon of a nationwide liberation movement that would come to be known as Black Christian Nationalism. The Shrine's members opened bookstores and co-ops, created a self-defence force, and raised their children communally, eventually working to establish the country's largest Black-owned farm, where attempts to create an earthly paradise for Black people continues today. Alongside the Shrine's story, Robertson reflects on a diverse array of Black utopian visions, from the Reconstruction era through the countercultural fervour of the 1960s and 1970s and into the present day. By doing so, Robertson showcases the enduring quest of collectives and individuals for a world beyond the constraints of systemic racism. The Black Utopians offers a nuanced portrait of the struggle for spaces - both ideological and physical - where Black dignity, protection, and nourishment are paramount. This book is the story of a movement and of a world still in the making - one that points the way toward radical alternatives for the future.
