The indigenous women of Onitsha known as “Ikporo Onitsha” have traditionally played critical roles in mediating conflicts, fostering dialogue, and preserving communal harmony through their cultural and social networks. This study investigates the challenges and successes of ikporo onitsha indigenous women-led peacebuilding efforts in Onitsha, Anambra State, Nigeria. Using a qualitative research design, data were collected through interviews and focus group discussions with 600 respondents, including key stakeholders and members of indigenous women’s groups. Quantitative data from the questionnaires was analyzed using descriptive statistics such as frequency counts and percentages. These were presented in charts for clarity. Qualitative data from the interviews was analysed thematically. Key themes related to challenges, successes, and the roles of women in peacebuilding were identified and interpreted. The findings reveal that socio-economic constraints such as lack of educational opportunities, cultural norms, economic challenges, and political exclusion hinder the effective participation of women in peacebuilding. However, Ikporo Onitsha women have employed strategies such as mediation, group discussions, and the involvement of respected elders to successfully resolve conflicts. The women have also achieved notable success in promoting reconciliation, reducing violence, and fostering social unity within the community. The study concludes that while Ikporo Onitsha women face significant barriers, their peacebuilding efforts have made a positive impact on maintaining social harmony. The findings suggest the need for policy reforms to enhance women’s participation in peacebuilding and greater recognition of their contributions. Additionally, the study provides insights for future research on indigenous women’s roles in peacebuilding across different regions.
