Dimensions of Conflict Behavior Within and Between Nations, 1955-1960 (ICPSR 5021)

Principal Investigator(s):


These data focus on the dimensions of domestic and foreign conflict behavior of nations in the period 1955-1960. The product of two separate studies conducted by Rudolph J. Rummel and Raymond Tanter utilizing identical variables for the time periods 1955-1957 and 1958-1960, respectively, this dataset gauges domestic conflict behavior with measures such as number of assassinations, general strikes, major government crises, purges, riots, anti-government demonstrations, revolutions, domestic violence deaths, and the presence or absence of guerilla warfare. Other variables such as the number of anti-foreign demonstrations, negative sanctions, protests, countries with which diplomatic relations were severed, expulsion or recall of ambassadors, threats, mobilizations, accusations, troop movements, deaths in foreign violence, presence or absence of military action, and war measure foreign conflict behavior.
