📥 What the dataset covers

A new, systematized dataset records every humanitarian military intervention between 1946 and 2015. It catalogs interveners’ proclaimed aims, mandates, and activities and documents events in target countries before, during, and after each intervention to enable robust evaluation.

🛠️ How the evidence is organized

• Data matrices and structured case descriptions accompany every entry.
• All coding decisions are documented in the case files to ensure transparency and reproducibility.
• The resource is designed for both quantitative analysis and qualitative case work.

🔎 Key findings from an initial review

• The spatial and temporal distribution of interveners and interventions challenges common assumptions.
• Contrary to a prevalent view, the majority of humanitarian military interventions are not exclusively conducted by Western states.
• The pattern of interventions did not simply decline after the missions in Afghanistan and Libya.

⚖️ Why this matters and what it enables

• The dataset is intended to stimulate comparative research on humanitarian military interventions.
• Despite a limited number of cases, the data can be used to investigate whether such interventions tend to reduce the duration and intensity of violence.
• The data can also help identify the conditions under which interventions lead to escalation or de-escalation of deadly violence, supporting a wide range of quantitative and qualitative studies.
