This book explores recent developments pointing towards a 'domestic institutionalisation of human rights', composed of converging international trends prescribing the setting up of domestic institutions, and the need for a national human rights systems approach. Building on new compliance theories, innovative arrangements have resolutely appeared around the turn of the millennium and some are now legally enshrined in human rights treaties. In their introduction, the editors capture these developments, their main elements and key points of debate. They outline a research agenda aimed at structuring and generating further attention from both academics and practitioners. As a stepping stone, the book singles out the purposeful attempt by the United Nations and others to frame these trends around the concept of 'National Human Rights System'. The chapters assess various models and cases put forward for such systems. Each chapter highlights the specific forms of institutions being promoted and their intended domestic interactions, and discusses how these institutions are leveraged and strengthened by international bodies. Authors critically review their implications for the future of human rights, paving the way for additional research. The chapters in this book were originally published as a special issue of the Nordic Journal of Human Rights.
