Formal Alliances, 1816-1965: an Extension of the Basic Data

Abstract

1 Classes of Alliance are : 1-Defense Pact; 2-Neutrality or Non-Aggression Pact; 3-Entente. 2 Asterisk (*) following termination date indicates that the alliance was superseded by another arrangement. 3 Parentheses around a year indicate that it applies only to the state alongside which it appears. 1 In addition to several master and doctoral dissertations which have utilized those materials, and some employment for teaching and simulation purposes, there are several other papers based on these data; see for example, Haas (1968) and Zinnes (1967). We have ourselves published two studies based on them; see Singer & Small (1967 and 1968). 2 Much of this work will be found in such journals as the present one, The Journal of Conflict Resolution, and Peace Research Society Papers, and a representative sampling is available in Quantitative International Politics (Singer, 1968). 3 The entire data deck may be had at nominal cost from the authors, or from Raymond Tanter, Director of International Relations Archive, ICPR, University of Michigan.
