The author is Toby Green, and the subtitle is West Africa from the Rise of the Slave Trade to the Age of Revolution. Here is one excerpt:
The past twenty years have seen a huge boom in studies that show the many different ways in which — even in the shadow of slavery — Africans were decisive actors in building modernity in the Americas. Rice-growing technologies in West Africa contributed to the emergence of rice plantations in South Carolina and northern Brazil; livestock and herding skills from West Africa were used by Africa herders in many parts of the New World, from Louisiana to Argentina; and fencing techniques were imported from West Africa and used in agriculture and in defending communities of runaway slaves (known as maroons). Healing practices from Dahomey and Angola were brought to Brazil and the Spanish Caribbean, and helped to develop new treatments in the colonies; healing practices and medicines were also borrowed by the Portuguese in Angola in an early form of ‘bio-prospecting’. Warfare techniques learn in the Kingdom of Kongo and in the Oyo-Yoruba Kingdom of what is now southern Nigeria were vital to the success of the Haitian revolution in 1804, as well as the rebellions against slavery in Brazil and Cuba in the early nineteenth century. In short, just as there were shared frameworks of diplomacy through which Atlantic African kingdoms sought political influence, so the modern world emerged from a mixed cultural framework in which many different peoples from West and West-Central Africa played a significant part.
This book is full of economics, currency movements (both gold and cowrie shells), battles between empires (Portuguese vs. Dutch, above all), and the longue durée. It is the “Braudel of West Africa,” and the best book on West Africa I have ever read. It is especially strong on Lusaphone Africa, and one underlying theme is that West Africa was globalizing even before colonialism came along. Toby Green, by the way, has an impressive background in philosophy and music as well as in history more narrowly conceived.
Very strongly recommended. It is not out until March of 2019 but you can pre-order now.
