Mexico's Dirty War and the Struggle for Accountability: A Conversation with Carlos Pérez Ricart.

Then & Now

In this week’s episode of then & now, guest host Professor Fernando Pérez-Montesinos is joined by Carlos Pérez Ricart, Assistant Professor in International Relations at the Center for Economic Research and Teaching (CIDE) in Mexico City, to discuss Mexico’s Dirty War—an internal conflict from the 1960s to the 1980s between the Institutional Revolutionary Party (PRI)-ruled government and left-wing student and guerrilla groups. As one of the four members of Mexico’s truth commission from 2021 to 2024, Carlos draws on the findings of this initiative to examine the country’s systematic use of violence and repression, as well as the most significant revelations from the commission’s comprehensive reports.
Carlos situates Mexico’s experience within the broader context of Latin America’s wave of repressive military regimes during the Cold War, which implemented widespread crackdowns on real and perceived political dissidents. While countries across the region began confronting these legacies in the late 1980s and early 1990s, the Mexican government remained largely unresponsive to calls for a truth commission, despite persistent demands from activists and human rights organizations. In 2021, the administration of President Andrés Manuel López Obrador (AMLO) finally initiated a formal process to address past abuses, creating a truth commission tasked with conducting interviews and scouring archives for evidence of past violence. This conversation considers the complexities of uncovering evidence implicating powers behind the formation of the truth commission itself and provides critical insights into the mechanisms of state violence, the politics of memory, and the challenges of transitional justice in contemporary Mexico.

Carlos Pérez Ricart is an assistant professor in International Relations at the Center for Research and Teaching in Economics (CIDE) in Mexico City. Prior to joining CIDE, he was a postdoctoral fellow at the University of Oxford, where he worked at both the History Faculty and the Latin American Centre, St. Antony’s College. His research and teaching interests include the relationship between Mexico and the United States, security and organized crime, arms trafficking, drug policies. He is co-editor of the book "Gun Trafficking and Violence: From The Global Network to The Local Security Challenge" (Palgrave, St. Antony’s College 2021).

Fernando Pérez-Montesinos is an associate professor in the Department of History at UCLA. His research focuses on the history of modern Mexico with a focus on the nineteenth century and the Mexican Revolution. His book, "Landscaping Indigenous Mexico: The Liberal State and Capitalism in the Purépecha Highlands" (UT Press, 2025), focuses on the Purépecha people of Michoacán, Mexico, and examines why and how long-standing patterns of communal landholding changed in response to liberal policies, railroad expansion, and the rise of the timber industry in Mexico.
