Typology of Armed Conflicts in International Humanitarian Law: Legal Concepts and Actual Situations

Although international humanitarian law has as its aim the limitation of the effects of
armed conflict, it does not include a full definition of those situations which fall within
its material field of application. While it is true that the relevant conventions refer to
various types of armed conflict and therefore afford a glimpse of the legal outlines of
this multifaceted concept, these instruments do not propose criteria that are precise
enough to determine the content of those categories unequivocally. A certain amount of
clarity is nonetheless needed. In fact, depending on how the situations are legally
defined, the rules that apply vary from one case to the next. By proposing a typology of
armed conflicts from the perspective of international humanitarian law, this article
seeks to show how the different categories of armed conflict anticipated by that legal
regime can be interpreted in the light of recent developments in international legal
practice. It also reviews some actual situations whose categorization under existing
legal concepts has been debated.
