A magnificent book with scholarly exploration of the Horn's intricate and complex history, politics, society including the regional and international dynamics. It is a very important contribution to the understanding of the Horn of Africa region with its own historical peculiarities, political complexities and nuances, and its long-standing interactions with the international and regional powers. I believe that it will serve as an essential work to be consulted by policymakers, academicians, think tanks, and other stakeholders from one of the most distinguished scholars on the Horn of Africa, Cristopher Clapham. The work provides different and complex levels of analysis in attempting to explain the region: society, state, international and individual-level analysis. I hope the book can also serve as a springboard for a new revival in the study and research of the Horn of Africa as a unique region in own terms.
