The Historic Bazaar of Yazd functions as a living heritage ecosystem embedded within the historic urban fabric, its continuity and resilience shaped by the historical interplay of social, cultural, economic, religious, political, and governance relations. Adopting a genealogical perspective grounded in an ecosystem framework, this study examines how transformations in socio-cultural concepts have affected the integrated conservation of the bazaar and reconfigured its indigenous conservation mechanisms over time. Within this framework, conservation is conceptualized not merely as physical intervention but as a dynamic socio-cultural process. The research employs an exploratory mixed-methods design across two phases. In the first phase, historical and documentary sources were analyzed using Grounded Theory procedures to identify key conceptual categories and their developmental trajectories. In the second phase, semi-structured interviews and Likert-scale questionnaires were used to examine the contemporary manifestations of these concepts, analyzed through systematic coding and exploratory factor analysis. The findings show that modernization, economic restructuring, institutional interventions, and shifting governance arrangements have significantly transformed traditional patterns of social interaction, collective organization, and everyday life within the bazaar. As a result, endogenous conservation capacities—including social trust, guild ethics, solidarity-based relations, customary regulatory systems, religious-cultural values, and self-regulating institutional structures—have weakened or been reconfigured. Nevertheless, collective memory, historical identity, place attachment, and shared cultural values continue to function as active components of the bazaar's living heritage ecosystem, sustaining social resilience and adaptive continuity. The study argues that effective integrated conservation of the Historic Bazaar of Yazd requires moving beyond a fabric-centered approach toward the recognition, reinforcement, and adaptive regeneration of the socio-cultural processes that sustain it as a living urban heritage system.
