Caption

The number of conflicts between states (red line) continued to increase sharply in 2025 and has now reached the highest level since World War II.

The Uppsala Conflict Data Program (UCDP) is widely regarded as the world’s leading source of data on organized violence. Its definitions of armed conflict have become the global standard for how conflicts are systematically categorized and analyzed. It remains the longest-running active effort dedicated to collecting and maintaining conflict data.
