Yoshio Kikuchi, "Two Thousand Years of Mercenaries" - A great book that will change the way you see world history! A recommended gem found in the process of studying Sacco di Roma!
The beauty of this work is that it allows us to look at history from the very beginnings of mercenaries.
This book is a very exciting look at historical changes from ancient Greece in terms of "mercenaries".
Humans have been fighting wars since long ago. But who was fighting those wars? Of course, the main players may have been royalty and nobility. But where did each soldier come from? And what kind of system has been used to conduct wars?
It is a terrific masterpiece that will completely change the way you see the world once you know it!
