Armed Conflict Location & Event Data (ACLED) is a non-profit organization registered in the United States that specializes in the real-time collection, analysis, and mapping of data on political violence and protest events around the world. It was founded in 2005 as a research initiative by political scientist Clionadh Raleigh. The organization codes information on events such as armed clashes, demonstrations, riots, and strategic developments, including the date, location, actors, fatalities, and event type. As of 2022, the dataset includes more than 1.3 million recorded events and offers updates through a global team of researchers and local partners.
The organization maintains partnerships with academic institutions, governments, international organizations, and humanitarian agencies. Its data and analysis are used by journalists, policymakers, researchers, and civil society to monitor conflict trends, support early warning systems, and inform decision-making in conflict-affected contexts. The project has expanded its coverage from a regional focus in Africa to a global scope.
