Version V3

This study contains data on 6,754 political instability events in 84 selected nations in the period 1948-1965. These data, which permit measurement of political instability and the correlates of internal conflict behavior, are concerned with conflict directed by groups and individuals in the prevailing political system against other groups or persons, and with uncovering the determinants of stability within all national political systems. The variables in the dataset are divided into four basic types: variables that identify events, classify events, describe events, and evaluate events. The study provides a conflict intensity rating for each event. Political instability events are classified from low to high and include institutionally prescribed elections, the fall of cabinets, martial laws, assassinations of significant group leaders, mass arrests, coup d'etats, and civil wars.
