Dwelling Place (2005)
His book Dwelling Place: A Plantation Epic is an "upstairs-downstairs" history of a white, slave-owing family and of a black enslaved family over four generations. At the center of the white family was a Presbyterian minister, Charles Colcock Jones, who became known among whites as the “Apostle to the Negro Slaves” for his work among the Gullah-speaking people of the Georgia lowcountry and his advocacy of humane treatment of slaves. The focus of the “downstairs” story is on the family of Lizzy Jones who family members helped created a remarkable slavery.Dwelling Place received the Bancroft Prize given by Columbia University for a work "of exceptional merit" in American history; the 2006 Bell Prize from the Georgia Historical Society for the best book on Georgia History; and a Mary Lawton Hodges prize from the Institute of Southern Studies, University of South Carolina; Steven Hahn, in his review in The New Republic called Dwelling Place "one of the finest studies of American slavery every written," and David Brion Davis of Yale called it in the American Historical Review "one of the best and most important studies of American slavery I have ever read."
By the Rivers of Water (2013)
Clarke's book By the Rivers of Water is the story of a remarkable Southern couple who freed in the 1830s their inherited slaves and helped them settle in the African American cology at Cape Palmas, Liberia.John Leighton Wilson and Jane Bayard Wilson served as missionaries, first at Cape Palmas and then in Gabon, for seventeen years. They were vigorous opponents of the international slave trade and French imperialism in Gabon. Leighton Wilson wrote the first dictionary and grammar of the Grebo and Mpongwe languages and reported on the stunning achievement of the Vey in developing their own alphabet. His book, Western Africa, was a careful and appreciative study of West African cultures and societies that sought to refute the claims of a rising scientific racism. The Dallas Morning News called the book an "Engrossing, elegantly written history...a memorable book" and the Library Journal, Starred Review, said it is “Brimming with insights about interconnected individuals, peoples, and societies struggling with conscience and dignity to make moral choices amid clashing, if not collapsing, worlds, this work is required reading for anyone interested in a sympathetic understanding of early U.S. missionaries in West Africa, the perils of the U.S. colonization movement, Civil War tensions, or Atlantic world connections.”
