Brian A. Catlos

Brian A. Catlos is Professor of Religious Studies at the University of Colorado Boulder and Research Associate in Humanities at the University of California Santa Cruz. He serves as Director of the CU Mediterranean Studies Group and Co-Director of The Mediterranean Seminar, an international scholarly forum with over 1,900 members worldwide. His academic appointments span multiple disciplines including Religious Studies, History, Ethnic Studies, Asian Languages and Civilizations, and Jewish Studies.

Dr. Catlos specializes in Christian-Muslim-Jewish relations, Medieval Mediterranean history, and ethno-religious minorities in pre-modern contexts. His research focuses on the complex dynamics of religious and ethnic identity in medieval Europe and the Islamic world, particularly in the Iberian Peninsula. He explores how religious minorities navigated political power structures while maintaining cultural and religious identities under majority rule.

His publications reveal a consistent focus on challenging simplistic narratives about religious conflict in medieval Mediterranean societies. Rather than portraying these societies as defined primarily by religious division, his work emphasizes the practical accommodations, economic interdependencies, and complex identities that characterized daily life across religious boundaries. His research demonstrates how religious identity often functioned alongside other social markers like language, profession, and regional affiliation.

Catlos has received numerous prestigious awards including the Medieval Academy of America's Charles Homer Haskins Medal (2018), the Middle East Studies Association's Albert Hourani Book Prize (2014), and a 2024 Guggenheim Fellowship. His books have been translated into numerous languages including Spanish, German, Polish, Korean, Russian, and Chinese.
