This chapter describes the security regime of the African Union(AU) mandated to promote peace and stability under the AU: the African Peace and Security Architecture (APSA) established in 2003. The chapter charts the institutional development of the mechanisms under the APSA against a volatile threat matrix and the deployment of these mechanisms in situational exigencies. It also illustrates the nature of the APSA as a security regime complex by unpacking the dense network of partnerships that operate within it. The chapter next demonstrates the pillars on which the APSA rests by engaging with select interventions made under each pillar. While the chapter concludes that the APSA has been proven to be an indispensable mechanism in addressing some conflicts, it also partly mirrors the past, present, and potential future of the large and fragmented continent it was designed for. The APSA is therefore not the penultimate representation of a collective security apparatus, but an evolving work in progress.
