Debate over how to recognize and understand change and continuity has long animated the field of International Relations. This Element brings norm-oriented and practice-oriented approaches into conversation to advance a wide-ranging account of change and continuity in global politics. It elaborates four scenarios in which norm and practice interactions produce change and continuity: relative continuity and a tight coupling of practices and norms; change through accidental incompetence; new competencies that create disjunctures; and change through deliberate contestation. It demonstrates the utility of the approach using empirical illustrations from the fields of global health and development. The Element also shows the wider applicability of the scenarios for major contemporary debates about change in global governance and security.
