Bridging Troubled Waters: History as Political Opportunity Structure

Abstract This article seeks to provide insight into the formulation of non-governmental organization (NGO) and transnational advocacy network (TAN) campaign strategy. We argue that the history of previous campaigns comprises an important aspect of the political opportunity structure faced by NGOs and TANs. We also argue that when formulating campaign strategy, campaigners should not only consider the legacies of previous campaigns, but also how their current strategies could impact on political opportunity structure and thereby influence future campaigns. This article uses the case study of the movement against seal hunting in Atlantic and Northern Canada and considers the potential for collaboration between previous opponents on other environmental issues. We examine the history of the anti-sealing campaigns looking at the various actors involved, and the impact that these campaigns had on these actors and their current relations with one another. The case study demonstrates that the history of previous campaigns matters and that history is a vital component of political opportunity structure.
