In the Mamluk Sultanate, high-ranking emirs constituted the most influential centers of power after the sultan. These emirs were brought to Egypt at a young age as slaves and trained in military institutions known as ṭibāq. Following their manumission, they served in various military roles and gradually formed the military-political elite of the state. Those who were talented and determined ascended to the highest ranks, even reaching the sultanate. The absence of a dynastic and hereditary system of succession provided these emirs with a legitimate claim to the throne but also led to fierce and often violent power struggles. The accessibility of the sultanate to powerful and influential emirs necessitated that potential candidates remain politically and militarily strong at all times. In this context, the study particularly examines the accession processes of Sultan Qutuz, Sultan Baybars, and Sultan al-Nasir Muhammad, aiming to reveal the role of high-ranking emirs in these transitions. It explores questions such as whether Sultan Qutuz secured the consent of other emirs during his rise to power and how a weak sultan navigated relationships with dominant emirs. The primary objective of this study is to demonstrate that the power held by emirs in the Mamluk state extended beyond military affairs, significantly influencing political decision-making and especially the selection of the sultan. Thus, emirs emerged not only as prominent figures within the military bureaucracy but also as critical actors in legitimizing the sultanate itself. The study adopts a qualitative research methodology, and based on the analysis of relevant sources, several key findings have been reached. The lack of a hereditary monarchy in the Mamluk political system rendered the sultanate vulnerable to the intervention of powerful emirs. Emirs frequently determined the ruler through consensus, and underage sultans were effectively governed by them. Ultimately, the legitimacy and continuity of power in the Mamluk state depended not on dynastic lineage but on securing the support of emirs and managing the balance of military and political forces. While this structure increased the military dynamism of the state, it also occasionally undermined administrative stability and caused significant fractures in domestic politics.
