Inge Van Hulle, Tilburg University, has just published Britain and International Law in West Africa: The Practice of Empire (Oxford University Press). The book appears in the OUP series, The History and Theory of International Law. Here is the abstract:
The book argues that, by the 1880s, the legal techniques that were fashioned in the language of international law in West Africa had largely developed their own substantive characteristics. Legal ordering was not done in reference to adjudication before Western courts or the writings of Western lawyers, but in reference to what was deemed politically expedient and practically feasible by imperial agents for the preservation of social peace, commercial interaction, and humanitarian agendas.
