Transactional Data Bank of International Conflict and Amity Events

This study contains data on about 7,025 conflictual and friendly events between 84 countries and 40 international organizations in the period 1954-1961. Data are provided for hostile transactional events, ranging from protests, accusations, and recall of officials to quasi-military actions, troop mobilizations, and war, and for amity events, ranging from offers to negotiate and confer to exchanges, agreements, and alliances. Events are qualified in 19 categories, including date, initiator, target, location, nature and intensity of event or tension, presence of violence, duration, number involved, killed, injured, or arrested, amount of military and civilian property damage, monetary exchange, politically significant persons involved in the event, and third parties involved in the event. The direction of the event and its retaliatory or nonretaliatory character are also included. A summary scale was developed by the investigators to measure the intensity levels of both hostile and friendly behaviors characterizing the event.
