This present book examines some of the key features of the interplay between legal history, authoritarian rule and political transitions in Brazil and other countries from the end of 20th Century until today. This book casts light on these aspects of the role of law and legal actors/institutions. In the context of transition from authoritarian rule to democratic state, Brazil has produced a significant literature on the challenges and shortcomings of the transition, but little attention has been given to the role of law and legal actors/institutions. Different approaches focus on the legal mechanisms, discourses and practices used by the military regime and by the players involved in the political transition process in Brazil. A comparative perspective that takes into account different political transitions – and their legal consequences – in Europe and Latin America complements the analysis. Part 1 (4 essays) discusses some of the central issues of political transition and legal history in contemporary Brazil, focusing on the time of the transition (and its effects on transitional justice) with different perspectives, from racial and gender issues to constitutional reform and police repression. Part 2 (3 essays) brings the comparative studies on South American experiences. Part 3 (4 essays) analyses different cases of transition to democracy in Chile, Portugal, Spain and Italy. Part 4 (3 essays) proposes a historiographical and methodological approach, considering the politics of time involved in the interplay between political transitions and legal history.
