International actors often intervene before civil wars begin. This study examines how the UN Security Council (UNSC) uses diplomatic measures to prevent self-determination movements from escalating into full-scale conflict between 1960 and 2005.

### Data & Methods

We analyzed UNSC actions in all self-determination disputes during this period, distinguishing between direct interventions addressing specific conflicts and indirect methods like sanctions or military force that influence actor incentives. Using quantitative analysis of these cases allowed us to identify patterns linking UNSC measures with conflict onset.

### Key Findings

Our results show two main pathways by which the UNSC successfully prevents violence:

* Direct Diplomacy: Actions tailored specifically to disputes significantly reduce their likelihood.

* Indirect Prevention: Sanctions and military force, while less direct, exert preventive power through broader influence on decision-making processes.

### Why It Matters

This research provides crucial insights into effective conflict prevention strategies. Understanding how the UNSC's specific actions correlate with peace outcomes offers valuable lessons for policymakers seeking to resolve disputes peacefully before violence erupts.
