Ira Berlin ranks as one of the greatest living historians of slavery in the United States... The Long Emancipation offers a useful reminder that abolition was not the charitable work of respectable white people, or not mainly that. Instead, the demise of slavery was made possible by the constant discomfort inflicted on middle-class white society by black activists. And like the participants in today's Black Lives Matter movement, Berlin has not forgotten that the history of slavery in the United States–especially the history of how slavery ended–is never far away when contemporary Americans debate whether their nation needs to change.–Edward E.
