This thesis examines the theory and practice of humanitarian intervention in the early post-Cold War era. Taking as its basis US policy towards Somalia, Rwanda and Haiti between\ud
1992 and 1994, it develops a theory of humanitarian intervention based on constructivist\ud
and scientific realist principles. Using identity as the organising concept, the thesis\ud
examines the meta-theoretical precepts of constructivism and scientific realism, which are\ud
developed into a methodology for analysing questions of foreign policy. Incorporating\ud
critical insights from sequential path analysis, morphogenetic social analysis - the notion\ud
of a dynamic mutual constitution of structure and agency - and constructivist social theory,\ud
the case studies provide a useful new means of conceptualising humanitarian intervention\ud
as a foreign policy practice through an identity-driven analysis. The findings of the\ud
research shed much light on this practice and its future prospects. They also suggest new\ud
directions for a scientific realist/constructivist research agenda
