Social tolerance, meaning endurance, resilience, broad-mindedness, patience, freedom of speech, expression of opinion, and consensus based on collective measures, forms the foundation for the emergence of an Islamic government and the continuation of religious governance. The primary objective of this research is to study the application of social tolerance strategies in Islamic-Iranian governance. The research methodology is quantitative meta-analysis (survey) using the CMA2 software and non-probability sampling method. From a statistical population of 46 documents from 2004 to 2023, after screening and applying inclusion and exclusion criteria, 35 documents (sample size) were selected while considering validity and reliability. The results indicate that political factors (awareness of civil rights, ethnocentrism, political culture, political participation); cultural factors (cultural intelligence, cultural capital, use of mass media, level of religiosity); psychological factors (moral individualism, hope for the future, relative deprivation, resilience); social factors (social cohesion, feeling of social discrimination, life satisfaction, social participation); and demographic factors (education level, income level, socio-economic status) influence social tolerance.
