My work focuses on civil-military relations and civil war. I am interested in particular in the dynamics of military coups, the spread of militarized policing, and the ways in which armed groups build legitimacy. My book, How to Prevent Coups d’état: Counterbalancing and Regime Survival, was published by Cornell University Press in 2020. My research has been published in published in the Journal of Peace Research and Journal of Conflict Resolution, as well as Foreign Affairs, The Washington Post, and Political Violence at a Glance. It has also been mentioned in The New Yorker, New York Times, Washington Post, Vox, Slate, and MSNBC, among other places.
I am currently working on a National Science Foundation-funded project on the determinants of civilian support for criminal and political armed groups in Colombia, as well as a project on the spread of militarized policing internationally.
I received a PhD from the Department of Political Science at Yale University in 2014, and a BA from Columbia University in 2004. I worked previously as a Research Associate in U.S. Foreign Policy and International Law at the Council on Foreign Relations and as a Research Associate in the Fellows Program at the New America Foundation in Washington, D.C.
At Hamilton, I serve as the Director of the Justice and Security Program at the Arthur Levitt Public Affairs Center, and organize the Women in Political Science lecture series. I teach courses on international security, civil-military relations, civil wars, and U.S. foreign policy.

How to Prevent Coups d’état: Counterbalancing and Regime Survival
Cornell University Press, 2020
In this lively and provocative book, Erica De Bruin looks at the threats that rulers face from their own armed forces. Can they make their regimes impervious to coups?
How to Prevent Coups d’état shows that how rulers organize their coercive institutions has a profound effect on the survival of their regimes. Where rulers use presidential guards, militarized police, and militia to counterbalance the regular military, efforts to oust them from power via coups d’état are less likely to succeed. Even as counterbalancing helps to prevent successful interventions, however, the resentment that it generates within the regular military can provoke new coup attempts. And because counterbalancing changes how soldiers and police perceive the costs and benefits of a successful coup, it can create incentives for protracted fighting that result in the escalation of coups into full-blown civil war.
Drawing on an original dataset of state security forces in 110 countries over a span of fifty years, as well as case studies of coup attempts in Asia, Africa, Latin America, and the Middle East, the book sheds light on how counterbalancing affects regime survival. Understanding the dynamics of counterbalancing, the book shows, can help analysts predict when coups will occur, whether they will succeed, and how violent they are likely to be. The arguments and evidence in this book suggest that while counterbalancing may prevent successful coups, it is a risky strategy to pursue—and one that may weaken regimes in the long term.
“Erica De Bruin has brought the study of coups into the twenty-first century. Cogent and compellingly argued, her book shows us how a common tactic employed by autocrats—establishing multiple, competitive security forces—may help prevent, but may also at times encourage, conspiracies against the government. How to Prevent Coups d'État is a major contribution to scholarship on comparative politics and civil-military relations.”
—Risa Brooks, Marquette University, author of Shaping Strategy
“De Bruin has meticulously collected a vast swath of original, reliable, global data and leveraged the data through an excellent research design to finally resolve debates about the design of coercive institutions and the impact on regime survival.”
—Caitlin Talmadge, Georgetown University, author of The Dictator's Army
“Erica De Bruin’s excellent book is an important contribution to the scholarship on civil-military relations. She has identified a real lacuna in the literature, as those of us who have thought about coups rarely considered the role of counterbalancing institutions explicitly, let alone viewed them through a theoretical lens.”
—Zoltan Barany, University of Texas, author of How Armies Respond to Revolutions and Why
"Erica De Bruin's book offers the most comprehensive account to date of whether counterbalancing (or coup proofing) can deter coup attempts....[it] deserves to be read not only be academics and dictators, but by anyone interested in research on coups."
—Jerg Gutmann, University of Hamburg, Journal of Peace Research
"A captivating and informative exploration of how leaders structure their 'coercive institutions' to protect their regimes from their own armed forces....should be a staple in any course on civil-military relations and read alongside classics including Eric Nordlinger’s Soldiers in Politics, Samuel Finer’s The Man on Horseback, and Samuel Huntington’s The Soldier and the State."
— Ricardo A. Crespo, Journal of the Middle East and Africa
The global spread of militarized policing
Riot Squads, SWAT Teams, and Tactical Units, 1960-2020
Policing is a central function of states. In many communities, the police are the only state agents that people interact with on a regular basis. In recent years such interactions have grown more violent, as police forces around the globe have become more militarized – adopting the weaponry, tactics, and organizational structures of military forces. To track the global spread of militarized policing, I compiled data on the formation of riot squads, SWAT teams, and other militarized special units within national and federal-level police agencies in 170 countries around the globe, 1960-2020. Figure 1 (right) shows the creation of militarized police units across the globe between 1960 and 2020. Each dot represents the creation of a new militarized unit.
Mapping coercive institutions
The State Security Forces Dataset, 1960-2010
How rulers organize and use their security forces has important implications for regime survival, repression, and military effectiveness. Yet efforts to understand systematic patterns have been hampered by a lack of reliable data that can be compared across states and within them over time. The State Security Forces (SSF) dataset, which includes 375 security forces in 110 countries, 1960-2010, tracks how each security force is commanded, staffed, equipped, and deployed, as well as the number of security forces and potential counterweights in each state’s security sector as a whole. Figure 2 (left) shows the highest number of security forces in operation in each country between 1960 and 2010.

Women in Political Science
I organize the Women in Political Science lecture series at Hamilton College, which brings senior scholars in political science to campus to mentor junior faculty in the social sciences. In addition to giving research talks, scholars in the series present oral autobiographies of their careers to junior faculty women in the social sciences. The autobiographies focus on the career choices scholars have made, challenges they have faced along the way, and advice for junior faculty navigating the tenure track. The goal of the speaker series is to help foster a supportive campus climate for female faculty. It was inspired by the autobiography lunches at Journeys in World Politics.
Speakers in the series have included:
Eva Bellin, Brandeis University
Kelly Greenhill, Tufts University/Harvard
Mary Gallagher, University of Michigan
Vesla Weaver, Johns Hopkins University
