Presidents for Life in Sub-Saharan Africa: Unpuzzling Authoritarianism in Zimbabwe and Rwanda offers a compelling and nuanced analysis of the political strategies employed by the semi-authoritarian regimes of Robert Mugabe and Paul Kagame to secure and sustain legitimacy. Using a multidimensional framework, the book employs process tracing to examine the interplay between historical narratives, legal and institutional frameworks, economic policies and outcomes, state–civil society relations, and foreign policy choices in both countries—revealing the multi-causal dynamics underpinning semi-authoritarian resilience. This book is an essential resource for scholars, students, and practitioners of African politics, authoritarianism, and international relations.
