Abstract
This chapter examines the role that international organizations play in world politics. It explains what international organizations are, whether we need international organizations in international relations, and what constraints and opportunities exist for international organizations to achieve their mandates. The chapter also considers the reasons why states create international organizations and how we can analyse the behaviour of such organizations. Two case studies are presented: the first looks at Africa's premier financial institution which is the African Development Bank which was created in 1964 to facilitate regional cooperation and financial autonomy and the second considers ‘non-liberal’ IOs with a specific examination of the Shanghai Cooperation Organisation.
