Contemporary power and decolonisation discourses reflect how Eurocentric and Western analysis has shaped our understandings of the world. Decolonisation efforts within Global Health and feminist studies (including what counts as valid forms of women's organising) also requires a reclaiming of praxis developed within historically oppressed countries lost through erasures of knowledgeproduction. Our work contributes to these efforts through an analysis of a form of collective activism for women's health and development in Zimbabwe: the Nhanga. This traditional cultural practice is anchored to intergenerational women only 'safe spaces', a praxis pre-dating second wave feminist theorising on such ideas. Currently, Nhangas are used by the Rozaria Memorial Trust across community, national and global advocacy spaces to promote women's health. Using collaborative autoethnography, each author's personal accounts of engagement in the Nhanga interrogate the processes that promote change in women's lives. Our analysis suggests that the Nhanga fractures systemic, institutional and relational power through leveraging culture, emotions and narrative, in spaces where such dynamics are often overlooked. We conclude that the method offers a valuable form of collective organising: fully engaging with the complex relational, political, social and cultural environments that impact on health, through a quiet activism anchored to emotion, connection and reimagining of culture to promote change at individual, community and global levels.
