Legal frameworks are important for institutionalising and strengthening social protection systems. Two states in Nigeria, Jigawa and Zamfara, have enacted social protection laws. This article explores how the process of enacting such a law is influenced by state-level politics and local contexts, and how the activities of a project financed by the Foreign, Commonwealth & Development Office (FCDO) contributed to much greater understanding and acceptance of social protection in both states. Primary data collected through in-depth interviews with state and non-state stakeholders and project staff was analysed to tease out the political, cultural, and power dynamics involved in enacting the laws. Findings show that a range of factors aimed at building the case for, and understanding of, social protection across a range of stakeholders was critical, and that a fairly standard package of tools employed in advocating for institutionalising social protection was influenced considerably by domestic political dynamics.
