The pursuit of peace, stability and economic development are the main objectives of numerous regional organizations. Over the last decades, comparative approaches to regional phenomena received increasing attention but were often Eurocentric (Breslin and Higgott 2000: 343, Sbragia 2008: 33). In contrast, this chapter focuses on two regional organizations, which are less often considered in cross-regional analysis: the League of Arab States (LAS)1 and the Economic Community of West African States (ECOWAS).
