Women's participation in nighttime gatherings during the Third Imposed War reflected the promotion of self-sacrifice and national identity in line with the country's overarching policies. Despite family responsibilities, women attended these gatherings and strengthened social solidarity. This study explored the resilience model of women participating in these gatherings, emphasizing the role of national policy documents, using grounded theory. Participants were 15 Tehran-based women who had attended at least 14 nights, selected through purposive and snowball sampling. Data were collected through semi-structured interviews and analyzed using open, axial, and selective coding. Findings identified five key factors underlying women's resilience: patriotic duty, support from others, faith and intellectual independence, collective solidarity and coordination, and practical household management. Despite personal concerns and everyday constraints, these factors strengthened national identity and pride, fostered positive personal and psychological changes, enhanced social influence, and sustained long-term commitment. Understanding women's resilience in wartime can advance women's studies and inform crisis-management policies and efforts to promote women's social participation. The study recommends documenting the narratives of women who attended these gatherings through oral history and using them as a basis for documentaries and scholarly research. This would preserve their experiences for future generations and deepen understanding of how women's resilience develops through social action during wartime.
