KOSVED provides detailed information on the magnitude and location of events of one-sided violence in 20 civil wars. Schneider and Bussmann (2013) describe the data set in detail. Information on the variables can be found in the KOSVED codebook

One-sided violence occurs frequently during war. Systematic research on this form of violence, however, only started to emerge since the 1990s. Most existing data sets only include information about the most serious episodes of one-sided violence like mass killings or genocides, or are temporarily or spatially highly aggregated. The KOSVED project offers detailed information about particular instances of one-sided violence.
