'Mohammad Shahabuddin has now written a timely, theoretically informed, and empirically grounded book on the subject of ethno-nationalism, postcolonial states, and international law. It continues the pathbreaking work Shahabuddin began with his previous monograph Ethnicity and International Law (2016). His work deserves to be read by anyone interested in the fate of minorities and subaltern groups in postcolonial states.' B.S. Chimni, Foreword
