Siege Warfare and Military Organization in the Successor States (400-800 Ad)

Siege Warfare and Military Organization in the Successor States is the first study to comprehensively treat an aspect of Byzantine, Western, early Islamic, Slavic and Steppe military history within the framework of common descent from Roman military organization to 800 AD. This not only encompassed the army proper, but also a greater complex of client management, private military retinues, labor obligations and civilian conscription in urban defense that were systematically developed by the Romans around 400, and survived to be adopted and adapted by all successors.

The result was a common post-Roman military culture suitable for more restrained economic circumstances but still able to maintain, defend and attack city walls with skills rivalling those of their Roman forebears.
