The United States Political Violence Database

The United States Political Violence (USPV) database describes the dynamics of sociopolitical instability in the United States between 1780 and 2010. The database was constructed by digitizing data collected by previous researchers, supplemented by systematic searches of electronic media archives. It includes 1,590 political violence events such as riots, lynchings, and terrorism. For further details, see

Note that the first column on the Posted Data sheet, “code”, indicates the status of an event, with “D” referring to a duplicate, and “X” referring to an event that doesn’t fit one of the criteria for inclusion in the database as a legitimate political violence event. In other words, the summaries in the “analysis” sheet are based on data that exclude lines marked with D or X.
