This Master’s Seminar aims to critically analyze processes and forms of local intervention, including humanitarian issues, development aid and peacekeeping missions. Students must be able to identify the nature and dynamics of external intervention, as well as its agents and contexts; mapping responses/(re)actions to situations of violence; and critically explore the translation of intervention models into policy and practice. These objectives are aimed at developing analytical skills with a strong empirical component. By studying specific case studies, students will better understand the relationships between policy and practice. By linking security, development and humanitarianism in their interventionist logics, in geographically diverse case studies and where the EU played a prominent role, the proposed program contributes to deepening the knowledge of these matters and the development of critical skills. The role of the EU and its assumptions, decision-making processes and policy in these dimensions is emphasized, as well as its relations with the chosen case studies and with other relevant international actors.
