Social Impacts of the Arab Conquests in the Early Eighth Century Bactria

This study analyses the complex social impacts of the Arab conquests in Bactria during the early eighth century, moving beyond simple Arabicisation and Islamicisation models. Based on an analysis of Arabic historical narratives and Bactrian and Arabic documentary sources, the article demonstrates that the conquests and their effects were highly non-linear, dictated by evolving local and regional socio-political contexts. The primary catalyst for sustained social change was the Umayyad policy shift from isolated military garrisons to urban settlement among the local population in cities like Balkh. This intensive, reciprocal social contact triggered the widespread adoption of Islamic ideology, legal regulations (e.g., manumission laws), institutions, and infrastructure (mosques), even as Arabs assimilated Bactrian legal and cultural norms. Crucially, while Islamicisation advanced steadily, Arabicisation failed to gain traction. This resistance can be explained by Bactria’s deeply rooted multilingual history, demonstrating that socio-religious transformation in the Eastern Iranian regions was profoundly asynchronous.
