In Watching the Watchers, Henry Thomson explores a central dilemma of authoritarian politics: how the construction, management, and control of coercive institutions shape regime stability and social order. The book is uniquely positioned, as the author extends comparative research across six countries of the socialist bloc—East Germany, Poland, Hungary, Romania, Czechoslovakia, and Bulgaria—analyzing the dynamics of their coercive institutions from the Stalinist period to 1989.
Central to Thomson’s argument is the role of the secret police as the cornerstone of authoritarian social order. Across central and eastern Europe, communist states relied on an integrated system of coercive power—including state security, the military, police, and party militias—to enforce compliance and preempt dissent. Sustaining authoritarian order, both within the ruling hierarchy and society depended on institutions holding a monopoly over the means of violence. By granting security agencies the power and autonomy to surveil, detain, and neutralize threats, regimes enacted what Thomson terms the delegation of violence, highlighting that authoritarian social order is maintained through coercion.
The first part of the book examines why post-Stalinist regimes varied dramatically in the capacity of their coercive institutions (measured by agent and informant numbers, tenure, resources, and autonomy). Stalin’s model served as the blueprint across postwar central and eastern Europe, and thanks to their shared Soviet inheritance, these agencies were initially almost identical. Stalin’s death marked a turning point: coercive agencies began to diverge in size and power. Thomson tracks changes in structures, staffing, informants, and activities, showing how some states expanded forces while others reduced them. He argues that coercive capacity correlates with social disorder: larger, well-resourced institutions, as in East Germany and Romania, conducted extensive surveillance and preemptive repression, keeping public disorder low. Smaller agencies were less able to anticipate opposition, resulting in higher unrest often met with reactive and indiscriminate violence.
The variation in secret police size and capacity reveals a structural tension of socialist authoritarian governance: control over violence grants coercive institutions power and autonomy, reinforcing the regime while simultaneously posing a potential threat. This tension—captured by the question, Who will guard the guardians?—underscores the challenge of building effective coercive institutions while keeping them subordinate to political authority. In balancing empowerment and control, the regime’s stability is itself at stake.
The book’s core argument links elite cohesion, coercive capacity, and social order. Because dictators cannot rule alone, political elites can control the secret police only when the ruling coalition acts collectively. Elite cohesion determines the ability of elites to jointly control actors who hold the means of violence and to discipline coercive agents, thereby shaping regimes of repression. Where post-Stalinist transitions disrupted elite unity, weakened coalitions attempted to limit threats from subordinate coercive agents through leadership turnover, reduced autonomy, and cuts to resources. These measures, however, undermined preventive surveillance, intelligence-gathering, and overall coercive capacity, contributing to mass social disorder. By contrast, regimes that preserved Stalinist leadership maintained cohesion and strong security apparatuses, enabling more proactive, largely non-violent repression. Thomson’s framework thus explains why regimes with similar ideological and institutional legacies produced markedly different patterns of repression and social (dis)order.
To illustrate this argument, the second part of the book presents a comparative historical analysis of East Germany and Poland as two divergent postwar trajectories. While the GDR largely preserved a Stalinist leadership model, Poland underwent a post-Stalinist transition that produced significant reductions in coercive capacity. Thomson shows how, across different temporal sequences and institutional pathways, the breakdown of elite cohesion weakened coercive apparatuses and contributed to escalating social unrest, culminating in regime collapse.
The third part extends the argument through a comparative quantitative analysis of coercive institutions across central and eastern Europe. Using a difference-in-differences approach and data from six countries across multiple periods, Thomson examines how variation in intra-elite cohesion shaped the management of coercive agents and, in turn, levels of coercive capacity (measured primarily by institution size). He links these differences to patterns of social order, testing his claims across cases that, despite shared ideological and institutional inheritance, followed markedly divergent trajectories.
Thomson sets out the ambitious goal of developing a universally applicable explanation of coercive institutions across authoritarian regimes—a claim to be tested in other comparative contexts. The book succeeds in bringing together diverse cases to show how institutional design and elite oversight shape the inner workings of socialist authoritarianism. By focusing on one of the most obscure yet fundamental pillars of dictatorship—the coercive apparatus—Watching the Watchers illuminates the dynamics that sustain authoritarian rule. Combining quantitative analysis with historical case studies, it provides a comparative account of central and eastern European secret police and offers a fresh lens on the challenges of wielding and controlling coercive power in authoritarian regimes.
