Tracing the Security Dilemma in Civil Wars: howfear and insecurity can lead to intra-state violence?

Daniel Pinheiro Rio Tinto De Matos Supervisors: Professor Nicholas Wheeler and Professor Stefan Wolff

My doctoral research explores the scholarship on the Security Dilemma, as to understand the conditions and characteristics of its application to intra-state violence. My main question is if, and how, interactions between security seekers can be triggers of armed violence, challenging the dominant view that civil wars are exclusively sparked by actors with malign intentions towards each other, and to do so, I examine the cases of post-decolonization violence in Angola and Mozambique.


I have contributed with the Brazilian Navy Naval War College (EGN), the Brazilian Combined Center for Peace Operations (CCOPAB), the Portuguese Institute of International Relations (IPRI), the Portuguese Institute for National Defence (IDN) and Oxford Analytica. I spent time as Intern with the Knowledge Management and Innovation Team at the Portuguese Agency for Administrative Modernization, dealing with bilateral and multilateral international projects regarding matters of e-government. I volunteered for twenty months as a Firefighter and EMT specialist with the Mafra Volunteer Firefighters, and received a training accordingly.
