This thesis explores how women participated in the Myanmar peace process (2011–2021) and the ways in which they influenced the high-level negotiations and outcomes of such negotiations. This thesis addresses this question by exploring women’s motivations for participating in the peace process, the roles they played in the peace process and the challenges they experienced, as well as the impact of their participation on the negotiations and outcomes. Using a Black feminist framework and the Myanmar peace process as a case study, this research analyses how women can use their marginal (“outsider-within”) positions in formal peace processes. The empirical fieldwork for this thesis entails in-depth interviews with 49 key informants and six focus group discussions with selected women’s groups conducted between September and December 2019 across ten locations in Myanmar. Examination of women’s experiences of, and perspectives on, the peace process allows for an exploration of the gender dynamics of the high-level peacemaking and wider political transitional processes in Myanmar between 2011 and January 2021. The findings of this study demonstrate women’s agency for shaping high-level peace negotiations. The theory of Black feminist thought (BFT) made it possible to capture the multiple marginal voices and experiences of the different women in Myanmar involved in the peace process and broader peacebuilding. The thesis uncovers how women in Myanmar, although marginalised from the high-level peace negotiations, draw on their outsider-within positions at and around the peace table to shape the negotiations and agreements. The thesis focuses on how women in Myanmar experienced the peace process and contributes to a nuanced scholarly understanding of the peace process in both the formal and informal spaces, thereby broadening the empirical and theoretical scopes of contemporary scholarship about Myanmar and contributing to women and peacebuilding more broadly.
