Arua Oko Omaka’s The Biafran Humanitarian Crisis, 1967–1970 is an important addition to the growing literatures on both the Nigeria-Biafra War and international humanitarianism. . . . Arua Oko Omaka’s book deserves a wide readership not only in African studies but in the fields of human rights and humanitarianism as well. It will appeal to the growing number of historians working through the legacies of the Nigeria-Biafra War and the history of international intervention in the 1960s and 70s, but it also speaks to current practitioners of humanitarianism. To that audience, Omaka offers a detailed case study of how good causes are made, mobilized, and instrumentalized.
