Constructivism
Ideas, identities and norms as the stuff of international politics.
Conceptual diagram, not data.
Constructivism holds that the most important features of international politics are social rather than material. Material capabilities matter, but their meaning depends on shared ideas: the same number of weapons can look threatening or reassuring depending on who holds them and how the relationship is understood.
Key thinkers. Alexander Wendt's article 'Anarchy is What States Make of It: The Social Construction of Power Politics' (International Organization, 1992) argued that self-help and power politics do not follow logically from anarchy itself. They arise from the way states interact and come to understand one another. Anarchy can therefore take different cultural forms, ranging from enmity through rivalry to friendship. Wendt developed this argument at length in Social Theory of International Politics (1999).
Core concepts. Constructivists study identities (how states see themselves and others), norms (shared expectations of appropriate behaviour) and the processes, such as socialisation and argument, through which these change. Interests are treated as products of identity rather than fixed in advance.
Debates. Critics question how far shared ideas can be measured and whether constructivism offers predictions as well as interpretations. Supporters reply that it explains change, for example the end of long-standing rivalries, that purely material theories struggle to account for.
Applying it today. Constructivist analysis asks how norms about the use of force, the protection of civilians or the legitimacy of peace operations are being contested or reinforced, and how states' narratives about one another shape whether a dispute is framed as rivalry or as enmity.
