Populist-nationalist ideologies pose a threat to women’s rights. This article examines to what extent national institutionalisation of international frameworks promoting women’s rights can weather the misogynistic political climate accompanying the global rise of populist nationalism. The post-2016 situation in the Philippines offers a testing ground for this problem due to the co-existence of President Duterte’s hypermasculinist national leadership with a strong history of institutionalisation of the UN’s Women, Peace and Security (WPS) agenda. Drawing from an analysis of WPS policy and (...) institutions in the Philippines between 2009 and 2019 and from field research and interviews with government agencies, local civil society organisations and international partners, this article argues that the WPS agenda will likely survive in the hostile environment. But it also finds that institutionalisation alone does not guarantee successful implementation. While the WPS agenda may ostensibly remain a national priority under populist-nationalist regimes, its progression has been halted. (shrink)
