The Maluku region constitutes one of Indonesia’s post-conflict areas that continues to experience long-term social consequences. The conflict not only resulted in physical destruction but also generated enduring social vulnerability manifested in fragmented social relations, weakened intergroup trust, and limited access to social and educational resources. This article aims to analysed the dynamics of post-conflict social vulnerability in Maluku from a sociological perspective, emphasizing how local communities interpret, experience, and respond to these conditions in their everyday social lives. The study employs a qualitative approach with a case study design, drawing on in-depth interviews, participant observation, and documentation of community-based social and customary practices. Data were analysed through thematic and narrative approaches to capture the interconnections between conflict memory, social structure, and community-based recovery mechanisms. The findings indicate that post-conflict social vulnerability in Maluku is structural, relational, and historical in nature; however, it does not entirely incapacitate the community’s social capacity. Customary institutions and community relations play a significant role in rebuilding social cohesion, facilitating social inclusion, and transmitting intergenerational peace values. These findings underscore that post-conflict recovery does not rely solely on formal state interventions, but also on the strength of local social and cultural practices and historical consciousness. This study contributes to the development of post-conflict sociology and the sociology of social inclusion by highlighting the importance of community-based approaches in understanding and managing social vulnerability.
