UCDP/PRIO armed conflicts 1946-: intensity by conflict-year

Every state-based armed conflict recorded by the UCDP/PRIO Armed Conflict Dataset v26.1, 1946-2025 (https://ucdp.uu.se/downloads/, keyless annual bulk ZIP, CC BY 4.0). Each row is one conflict in one active year: primary parties (side_a, side_b), incompatibility, intensity level (1 = minor: 25-999 battle deaths in the year; 2 = war: >= 1,000), cumulative intensity, conflict type (1 = extrasystemic, 2 = interstate, 3 = internal, 4 = internationalized internal), start and episode-end dates, and location mapped to ISO alpha-3 country codes (semicolon-separated when a conflict spans countries). Method: keyless download of the versioned annual CSV; internal UCDP actor/dyad ids and precision flags dropped. Caveat: estimates are revised in later annual releases.
