With the spread of Islam in Iran and the gradual consolidation of Shiism in some periods, Iranian art underwent transformation in formal and semantic areas. From the perspective of the sociology of art, these transformations can be analyzed in connection with the power structure, belief system, and collective rituals. During the Qajar period, metalwork became an arena for representing Shiite concepts. Objects such as mourning flags, kashkuls, and ritual instruments, using symbols such as the names of the Ahl al-Bayt (AS), prayers, claws, and sacred elements, played a role in organizing collective memory and Shiite identity. The simultaneous expansion of mourning rituals and the support of Shiism by the Qajar political structure paved the way for the spread of these works. These objects can be considered visual media that served to legitimize religion and strengthen social cohesion. The present study, with a descriptive-analytical approach and based on library studies and observation of works, explains the function and semantics of Shiite symbols in Qajar metalwork in relation to its socio-historical context. The findings show that these symbols, beyond decoration, had identity and cultural roles in establishing Shiism, and the methods of decoration and inscription appropriate to ritual spaces and social audiences played an effective role in transmitting ideological concepts and reproducing the official Shiite discourse.
