"Migration Histories represents a laudable attempt at going beyond disciplinary borders and bringing in conversation experts from multiple historical subfields, including Byzantine studies, Eastern European studies, Islamic Studies, and more. (...) Finally, this volume invitesfurther attention to issues left standing such as the interplay between Medieval migrations and cultural identity, gender or the environment." – Guillaume Bidaut, in: Orbis Terrarum 20 (2022), pp. 291-294
