MERCENARIES

The Complete History of Mercenary Warfare — All Continents, All Eras

For 4,500 years, hired warriors have toppled empires, built kingdoms, and changed the course of history. They have been pharaohs' bodyguards and popes' last defenders, conquerors of Athens and liberators of South America. Some were bought as children and died as sultans. Others deserted one army to become heroes of the nation they fought against.

Blood for Gold tells their story — not just the familiar European tales, but the full global picture: Buddhist monks with muskets in Japan, African admirals in India, Polish cavalry that terrified Germany for generations, and the only woman in history to command a mercenary army. Over three volumes spanning 2500 BCE to 2025, this series covers more than 130 mercenary groups across six continents, built on named commanders, specific battles, and primary sources.

The same questions resurface in every century: Can hired soldiers be loyal? What happens when governments lose control of the violence they outsource? And why, despite every attempt to ban them, do mercenaries keep coming back?

From bronze swords to cyber warfare, the answer is always the same — as long as there is gold, there will be blood.
