Caution: the 'Onset of Civil War' Stata (DTA) file unfortunately includes a minor error. The variables indicating onset of war after 2, 5, and 8 years of intermittency  are erroneously named 'waronse', 'waronse0', and 'waronse1', rather than waronset2, waronset5, and waronset8, as correctly specified in the accompanying Excel and readme files. We apologize for any confusion this may have caused.

The Armed Conflict IDs has been simplified in this release. Use the ID conversion table if you need the Old IDs for data management purposes. Combine ID with Year if you want a unique key for each observation in the Main Conflict Table.

For alternative, calendar-time data on onset and duration of intrastate conflict, visit the download page for Håvard Strand's Onset and Duration data. Note: these datasets are based on the previous version 3-2005 (1946–2004) of the Uppsala/PRIO Armed Conflict Data.
