The Uppsala Conflict Data Program (UCDP) has recorded ongoing violent conflicts since the 1970s. The data provided is one of the most accurate and well-used data-sources on global armed conflicts and its definition of armed conflict is becoming a standard in how conflicts are systematically defined and studied.
About UCDP
Conflict Data Collection
To develop a general definition of armed conflict and ensure that it is systematically applied to all relevant situations in the world. This definition is basic to the entire conflict data project. Data are published annually and covers the period after 1946.

UCDP Georeferencing and Event Dataset (UCDP GED) Project
The development of the UCDP GED is the next step in conflict data collection. The aim of the project is to provide the international community of scholars with data on organised violence that is disaggregated both spatially and temporally, so as to create opportunities for more fine-grained analyses of the causes, dynamics, and settlements of violent conflicts.
