Research

Kaegi was most recently involved in several projects, notably on Muslim raids into Byzantine Anatolia. He was planning an investigation of the role of Byzantine concepts of strategy in the emergence of concepts of strategy in early Modern Europe. Kaegi's research interests also included Byzantine commercial relationships with the Arabian Peninsula on the eve of the Islamic conquests. Additionally, he was preparing an essay on Byzantium in the 7th century for an Oxford University Press handbook to Maximus the Confessor. An avid reader of Arnold J. Toynbee in his formative years, Kaegi was writing a reassessment of Toynbee as a Byzantine historian.
