stday

the start day for the participant

endyear

the end year for the participant

endmon

the end month for the participant

endday

the end day for the participant

obsid_start

an observational ID from archigos for the leader at the participant onset

sidea

was participant on Side A of the dispute

hiact

Details

Information about leaders come from Archigos (v. 4.1). GML MID Data are version 2.2.1. The data-raw directory contains information about how these data were generated. There is invariably going to be some guesswork here because dates are sometimes not known with precision. Sometimes, a dispute coincides even with a leadership change when dates are known with precision. The source script includes a discussion of these cases and shows how the data were generated with all these caveats in mind.

Do note that participants can have several episodes within a dispute. Sometimes participants switch sides (e.g. Romania in World War 2). Sometime participants drop in and out of a long-running dispute (e.g. Syria, prominently, in MID#4182).

"Dummy" start days and end days are there to serve as a parlor trick in assigning disputes to leaders in leader-level analyses. Where days are known with precision, the dummy day is that number. In most cases, where the day is not known with precision coincides with a month that has no leader transition. Thus, the start day that gets imputed is going to be the first of the month (for the dummy start day) or the last of the month (for the dummy end day). Cases where there was a leader transition (or two) that month may require some more sensitive imputing. For example, our best guess is Antonio Guzmán Blanco of Venezuela is president for the end of MID#1639, given his role in trying to negotiate a conclusion to the dispute. Archigos has him leaving office on the 7th, so that's the end day that gets imputed for him. Again, these are here to serve as a parlor trick in assigning disputes to leaders for leader-level analyses. Be careful about using these data for calculating dispute-participant duration. In fact: don't do that.
