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
UCDP External Support Data
UCDP’s data on external support in intrastate conflicts is divided into two separate datasetes, the UCDP External Support – Primary Warring Party Dataset, and the UCDP External Support – Disaggregated/Supporter Dataset. The two datasets are analogous, i.e. contain identical data structured in a different manner to simplify various types of research such as different types of statistical analyses.
Choosing the right dataset: The External Support – Primary Warring Party Dataset is best suited for analysis from the perspective of the receiver of support, as long as the analysis does not require the exclusion or inclusion of supporters, or the distinction of who supplied what. The External Support – Disaggregated/Supporter Level Dataset is best suited for analysis from the perspective of the supporter, (e.g. analyses on number of supporters in a given year, actions of a particular supporter in a given region, etc.) or for more complex analyses (excluding some supporters, excluding some types of offered support etc.). The basic difference from the UCDP External Support – Primary Warring Party Dataset is that, if more than one supporter gave support to a party in a year, each individual supporter is listed on a separate row. As such, types of support need not be aggregated, each row containing the types of support that each external supporter gave to a certain receiver in a given year.

UCDP External Support – Disaggregated/Supporter Dataset v. 1.0-2011
Content: a dataset where the unit of analysis is the warring party-supporter-year, i.e. each row in the dataset contains information on the type of support that a warring party receives from a specific external party in a given year, using dummy variables for each category of support. The dataset contains information for the time-period 1975–2010.

Major UCDP data release
On 8 December, 2011, the UCDP released its latest addition to its vast number of datasets; the UCDP GED version 1.0-2011. The UCDP GED is an event-based and georeferenced dataset on organized violence, detailing all of the UCDP’s categories of violence (state-based conflict, non-state conflict and one-sided violence) in Africa between 1989 and 2010 at the level of the individual event of violence.
Also on 8 December, 2011, the UCDP released new data on external support in internal armed conflicts for the time period 1975-2009.
