Published in 1999, Professor C.A. Macartney was one of the foremost 20th-century authorities on the history of the Danube basin. His life’s work included the re-examination of the sources relating to early Hungarian and Pontic history. This selection of his studies (some of them hardly accessible because they were published in wartime conditions) illuminates one of the dark corners of medieval Europe and tackles controversial questions in the history of the nomadic steppe peoples, such as the Magyars, Pechenegs, Kavars and Cumans. Macartney’s treatment of the earliest Hungarian written sources and their interpretation laid the foundation for his shorter book, The Medieval Hungarian Historians. The present volume brings together for the first time, and indexes, his series of detailed studies on this material; penetrating in both its analysis and scholarship, this work remains indispensable for our understanding of the period and its historiography.
