This chapter offers a conceptual framework for better understanding the long and often misrepresented history of social rights. It begins by debunking the common notion that social rights are ‘second-generation rights’ – that they are recent additions to ‘core’ civil and political rights that stretch back to the Enlightenment. After historicising this myth, the authors sketch out the long history of social rights presented in this volume, situating their origins across a wide range of sources: religion, liberalism, socialism, decolonisation, biopolitics, among others. Understanding the chronic precariousness of social rights, they argue, requires understanding their entanglements with notions of charity, justice, equality and, above all, ‘duties’ and ‘obligations’. The history of social rights, they insist, is inseparable from the problem of obligation – a problem with philosophical, legal and cultural dimensions. They conclude by linking the history of social rights to broader struggles over inequality, particularly those generated by class, race, gender, colonialism and globalisation.
