This study adopts a qualitative approach and, using historical-conceptual interpretation and documentary analysis, formulates the contexts for the emergence and continuity of “cultural defense” in the thought and practice of Shaykh al-Tusi. Its main question is which facilitating contexts made possible the emergence and institutionalization of this type of cultural strategy. The study is structured around a three-cluster model, and the findings indicate that: first, Shaykh al-Tusi’s individual capacities, together with his historical self-awareness and sense of timing, enabled purposeful and innovative action; second, the available intellectual capital and scholarly institutions, through educational guidance and the organization of knowledge production, contributed to strengthening the scholarly authority of the Imami school; and third, the cultural-political setting of the period, with a degree of religious tolerance and institution-building policies, made possible formal presence and the expansion of intellectual networks.

Overall, these factors enabled cultural defense to develop from the level of episodic responses into a strategic and organized form. At the level of research design, this study formulates a three-cluster model of facilitating contexts that can also be used to examine similar experiences in other historical periods.
