"Huffman's book is well researched and written in an appealing manner and - especially for an English-speaking audience - offers a good introduction to Cologne's city history."
- Markus Jansen, Rheinische Geschichte, January 2020. Originally published in German.
"Huffman has written a thorough, judicious, and excellent account of Cologne’s first millennium. Readers interested in the urban history of the post-Roman West will find this book particularly valuable, but it also has much to offer to those interested in early medieval Germany, as Huffman spends a great deal of time describing how Cologne fit into the context of Ottonian and Salian politics."
