Regional security arrangements as a filter for norm diffusion: the African Union, the European Union and the responsibility to protect

Regional security arrangements play a central role in modifying emerging norms as they travel from the global to the local level. This process of norm localization is shaped by various factors such as the characteristics of regional security cultures, corresponding resonance with the emerging norm, institutional voice opportunities, and mechanisms of framing and pruning as they are utilized by norm entrepreneurs. The article applies this analytical framework to the localization of the responsibility to protect (R2P) norm by the African Union and the European Union. Subsequently, the paper examines how localization of the R2P norm in both regions affected their reactions to the Libyan crisis in 2011. It also examines the likely ramifications that the intervention may have on the future reception of the R2P by African and European actors.
