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.

| Column | Type | Description |
|---|---|---|
| conflict_id | integer | UCDP conflict identifier; with year forms the primary key. |
| location | string | Conflict location country name(s) as spelled by UCDP, comma-separated when several. |
| country_codes | string | ISO 3166-1 alpha-3 code(s) for location, ';'-separated when several; historical entities keep stable documented codes. |
| side_a | string | Primary party A (always a government). |
| side_b | string | Primary party B (opposition organization). |
| incompatibility | integer | Stated incompatibility code (UCDP/PRIO codebook). |
| territory_name | string | Disputed territory, when the incompatibility concerns territory. |
| year | integer | Calendar year the conflict was active. |
| intensity_level | integer | UCDP intensity level for the conflict-year: 1 = minor armed conflict (25-999 battle-related deaths in the year), 2 = war (at least 1,000 battle-related deaths in the year). |
| cumulative_intensity | integer | Highest intensity level reached over the conflict's history (same 1/2 coding as intensity_level). |
| type_of_conflict | integer | UCDP conflict type: 1 = extrasystemic, 2 = interstate, 3 = internal, 4 = internationalized internal (UCDP/PRIO codebook). |
| start_date | string | Start date of the conflict episode (YYYY-MM-DD). (unit: date) |
| ep_end | integer | 1 when the conflict episode ended in this year. |
| ep_end_date | string | Episode end date (YYYY-MM-DD), when ep_end = 1. (unit: date) |
| region | string | UCDP region code for the conflict location (see the UCDP/PRIO codebook). |
| ucdp_version | string | UCDP dataset version the row was published in. |
First 10 sample rows — a preview, not the complete dataset.
