What is the relationship between religion and empire, and what role do religious ideas play in the empire-formation process? This paper focuses on these questions by analysing the role of Islam in the formation of the Umayyad and the Ottoman Empires. Although the literature about these Islamic empires is extensive enough, they generally provide a rich historical narrative without theorization. To fill this gap, I use constructivist theory in the analysis and point out that religion as a structural force helps states to turn into empires over time. Nevertheless, following the agent-structure debate, I also argue that the individual characteristics of these states are essential to understand how religion affected their policies and how they interpreted the religion. The findings show that as the Umayyad Empire was not recognized as legitimate by various sects in religious terms in the seventh and eighth centuries, religion played less of a regulatory role in imperial policies and its rulers did not hesitate to adopt ruthless stratagems and a divide-and-conquer strategy. On the other hand, the Ottoman Empire benefited from religion in its conquests and its policies were primarily restricted by religious norms and values. As a result of this dependence, ruthless stratagems were adopted less often, and Ottoman policies were heavily shaped by religious norms and values.
