Constructivism is an international relations theory that has arisen in recent years through assimilating the fruits of sociology, linguistics and other international relations theory. Constructivism has been particularly influenced by a shift towards linguistics within philosophy. There are many schools within constructivism – even within the mainstream constructivist camp there are the highly explanatory linguistic constructivism and a more moderate school which shares many aspects with realism. Even so, all constructivist schools have three common features. They believe interaction between actors creates social meaning, interaction between agents and structures creates identity, stress the impact ideas have on behavior. Constructivism highlights the role of individual activity and the power of culture and socialized relations in world politics. It is for these reasons that constructivism has enjoyed such success within international relations studies both at home and abroad in recent years.
