Université Paris 8: 'Religion, commerce and intrigue: abbé Demanet and his networks'

Jean-Baptiste Demanet's Nouvelle Histoire de l'Afrique françoise  (1767) is a source used by Raynal in book XI ofHDI. The abbé  himself, whom Raynal probably knew, was a colonial adventurer behind  several complicated schemes in West Africa and used his political  friends to launch a slave trading company. His claims about routes to  the interior of Africa were quoted in early editions of HDI, but  after being denounced by the French administrator in West Africa he  makes an anonymous appearance in 1780, as "un homme inquiet & ardent"  duping unsuspecting people. Demanet's support in government circles  undoubtedly facilitated his commercial ventures in the slave trade and  somewhat megalomaniac schemes, which led to his final downfall and  disgrace. This study, an attempt to unravel the career of this  colonial adventurer and his complicated and rather shady African  schemes against the background of Franco-British rivalry in West  Africa, will throw light both on Raynal's informers and on the  political networks which lie behind the text of HDI.
