UCDP

The Uppsala Conflict Data Program (UCDP) is the world’s main provider of data on organized violence and the oldest ongoing data collection project for civil war, with a history of almost 40 years. Its definition of armed conflict has become the global standard of how conflicts are systematically defined and studied.
