This chapter provides an overview of the emergence, consolidation, recalibration, and liberalization of employment policies in Spain. By identifying five developmental periods, it reviews transformations in the nature and regulation of labour market policies from the early 1900s to the mid-2010s. In addition, it explores changes in the territorial organization and governance of labour-market policies with a focus on decentralization, (re-) centralization, and delegation reforms. The chapter concludes with a discussion of the implications of the Great Recession on Spanish labour market policies and structures, including its dualized labour market. All in all, the chapter sheds much light on the nature and changes of the Spanish welfare state since the early twentieth century.
