Book excerpt: Ethnicity and Nationalism in Africa features a series of 'constructivist' contributions by leading scholars in the field of ethnicity and nationalism, and explores the differences among those who have come to be known as 'constructivists'. The contributors reflect upon ongoing methodological debates in ethnography, historiography, and political theory. They demonstrate the diversity of concepts and methods within constructivism, and assess the political implications of the concepts themselves. The debate between them is inter-disciplinary, critical and innovative, and should be of value to anyone interested in the study of ethnicity and nationalism.
