Introduces the UCDP External Support Dataset (ESD) covering external support to warring parties in armed conflicts 1975-2017. Presents three key empirical trends: dramatic increase in number of supporters, shift to pro-government interventions post-9/11, and rise of direct military intervention as predominant support mode. Supersedes the Högbladh, Pettersson & Themnér (2011) dataset with expanded coverage including non-state supporters and ten support type dimensions.
The study of empirical patterns and measurement infrastructure for external support in armed conflicts. Covers dataset construction, coding decisions, prevalence estimates, and secular trends in the type, direction, and multilateral nature of external support provision globally.
external-support-prevalence
External Support PrevalenceThe share of armed conflict-dyads or intrastate conflicts that receive at least one form of external support from state or non-state actors in a given time period. ESD documents: 80% of all intrastate conflicts (1975-2017) received external support; 72% of interstate conflicts. External support is the rule, not the exception, in modern armed conflict.
pro-government-intervention
Pro-Government InterventionExternal support provided to government forces (rather than rebel groups) in intrastate conflicts. After 9/11, the share of conflict-dyads with exclusively rebel-sided support fell to near zero by 2016, while government-sided support reached 77% of all active conflict-dyads by 2017. Reflects the international anti-terrorism norm shift that reframed rebel groups as terrorist organizations.
direct-military-intervention
Direct Military Intervention (Troop Deployment)External support involving deployment of foreign troops for combat operations on behalf of a recipient party. Coded separately from indirect support (weapons, training, funding, intelligence, logistics). Direct intervention first exceeded indirect support in 2015 and continues to grow. Conceptually distinct from delegation/orchestration framing by requiring actual combat role.
multilateral-support-coalition
Multilateral Support CoalitionThree or more states coordinating their provision of external support to achieve a common goal. Coalition-based support was rare before 2001 (Gulf War Coalition 1990-91 is the first recorded instance) but grew dramatically after 9/11, reaching nearly one-third of all support instances by 2017. Implications for effective principal discipline over rebel recipients.
non-state-supporter
Non-State External SupporterAn armed opposition organization or rebel group that provides external support to another warring party in a different conflict. ESD is the first global dataset to systematically track non-state actors as supporters (not just recipients). Non-state supporters peaked at 38 active groups in 2012 (including al-Shabaab training Boko Haram). More than a quarter of all support to rebel groups comes from non-state actors.
Domain: External Support Measurement and Trends
The study of empirical patterns and measurement infrastructure for external support in armed conflicts. Covers dataset construction, coding decisions, prevalence estimates, and secular trends in the type, direction, and multilateral nature of external support provision globally.
Temporal scope: 1975-2017 | Population: All state-based armed conflicts worldwide, 1975-2017
