This study examines how the rise of Fatimid power in the 10th century is represented in contemporary scholarly literature, focusing on Sicily and modern-day Tunisia. In 909, a Shia Ismaili dynasty emerged in a region previously Islamized and governed by the Aghlabid Emirate, which was nominally subordinate to the Abbasid Caliphate in Baghdad. The research critically addresses the tendency of historical narratives to focus on the Sunni-Shia conflict, often overshadowing the complex dynamics of the period that involved not only the religious sphere but also the legal, political, and military domains. While this division was undeniably significant, framing it as the exclusive lens risks reducing the rich historical tapestry of the era to a simplistic dichotomy. Instead, this study investigates how contemporary historiography has constructed this period, highlighting how modern narratives can reflect biases in the historicization of the Sunni-Shia contrast and the Fatimid rise to power. By doing so, it underscores how pre-existing tensions and multifaceted power struggles are often overlooked, filtered instead through the lens of contemporary geopolitical dynamics.
