Institutional Change and Conflict Regulation: The Anglo-Irish Agreement (1985) and the Mechanisms of Change in Northern Ireland

This article uses historical institutionalist theory to assess the impact of the Anglo-Irish Agreement of 1985 – often seen as the first step towards gradualist change in the role of the state in Northern Ireland. It uses new data to show how the elites who initiated the process conceived of it and to identify the mechanisms producing change. The study shows that the mechanisms of institutional change identified in comparative studies of industrial policy and welfare state development are also to be found in processes of intergovernmental ethnic conflict regulation. In turn, it highlights a mechanism of institutional change – ‘wedging’ – not discussed in the literature.
